• We rounded up real-life royals around the world that have Disney prince and princess doppelgängers.
• Princess Mette-Marit of Norway looks just like Elsa from "Frozen."
• Kate Middleton looks like Princess Belle from "Beauty and the Beast."

When Kate Middleton met with Mette-Marit, the crown princess of Norway, people commented that the pair of princesses were giving off "major 'Frozen' vibes."

But Princess Mette-Marit isn't the only real princess to resemble Disney royalty.

We rounded up princes and princesses from around the world— from the British royal family to the princess of Saudi Arabia — and matched them with their regal Disney doppelgängers. 

Kate Middleton reminds us of Belle from "Beauty and the Beast."

It's not too much of a stretch to see how the Duchess of Cambridge could be compared to Princess Belle. 

Princess Mette-Marit of Norway looks just like Queen Elsa from "Frozen."

Crown Princess Mette-Marit of Norway is married to Crown Prince Haakon, the heir apparent to the crown of Norway. 

Princess Lalla Salma of Morocco has the same fiery red hair as Merida from "Brave."

Princess Lalla Salma is the princess consort to Mohammed VI, the King of Morocco.

In 2013, Elon Musk, the famed entrepreneur and CEO of Tesla and Space X, came up with an idea for a vacuum-and-maglev-powered super-fast train that would travel through a tube. It would be called the Hyperloop.

In a research paper, he outlined its potential and challenged other tech companies to develop it for commercialization. Two startups, Shervin Pishevar’s Hyperloop One and Dirk Ahlborn’s Hyperloop Transportation Technologies, are perhaps the closest to making the Hyperloop a reality. Though it's still a moonshot project.

In July 2017, Musk revealed that he's working on his own system, tweeting that he "received verbal government approval" to build stops in Washington, DC and New York City. And on Tuesday, The Washington Post reported that his tunneling startup, the Boring Company, gained an "early and vague building permit from DC for excavation experimentation in a parking lot.

But Musk is not the first person to suggest air pressure-driven transportation. As io9 notes, the concept behind the Hyperloop originated in the late 17th century with the invention of the world's first artificial vacuum, which led to designs for "underground rapid transit systems" powered by pneumatics (i.e. pressurized air) in the decades that followed.

Take a look at a brief history of the technology that led to Musk's Hyperloop.

In 1799, inventor George Medhurst proposed an idea to move goods through cast-iron pipes using air pressure. In 1844, he built a railway station (for passenger carriages) in London that relied on pneumatics until 1847.

Throughout the mid-1850s, several more pneumatic railways were built in Dublin, London, and Paris. The London Pneumatic Despatch system was meant to transport parcels, but it was large enough to carry people, too. To mark its opening, the Duke of Buckingham traveled through it in 1865.

Around that time, French novelist Jules Verne published "Paris in the 20th Century," which envisioned tube trains stretching across the Atlantic Ocean.

In the mid-1860s, South London constructed the Crystal Palace atmospheric railway, which ran through a park. A fan, which measured 22 feet in diameter, propelled the train. On return journeys, the fan's blades reversed, sucking the carriage backwards.

• We put together a list of the world's richest black billionaires, using data from Forbes.
• The majority of the billionaires on the list are self-made self-starters who built business empires in finance, sports, media, and commodities.
• Only three of the billionaires are from the United States.

Bill Gates, Warren Buffett, and Jeff Bezos may be the richest men in the world, but they aren't the only billionaires.

There are 2,043 people across the globe with three commas in their net worths, according to the 2017 Forbes Billionaires list. The 23 wealthiest have $1 trillion collectively.

In 2017, 10 of the world's billionaires — fewer than 1% — are black, down from 12 last year, reports Forbes contributor Mfonobong Nsehe. Three of the 10 are women. All but one, Isabel Dos Santos, are billed by Forbes as self-made.

To compile the full list, Forbes uses stock prices and exchange rates to estimate the net worths of the world's richest people, and then ranks them based on their wealth. We updated the 2017 list using data from February 15, 2018. Forbes maintains a current snapshot of the world's billionaires, updated daily.

• Jessica Springsteen is the daughter of rock-and-roll artist Bruce Springsteen.

• The 26-year-old began riding horses at a young age, and has become a top equestrian.

• She reportedly has her eyes set on the 2020 Tokyo Olympics.

You might say that Jessica Springsteen was born to ride.

The only daughter and middle child of rock-and-roll legend Bruce and his wife Patti Scialfa — who are worth around $75 million, according to Forbes — has been riding horses from an early age.

Springsteen, her parents, her older brother Evan, and her younger brother Samuel moved from Los Angeles to New Jersey in the early 1990s. According to John D. Luerssen's book "Bruce Springsteen FAQ: All That's Left to Know about The Boss," the couple wanted to give their kids "a more normal life experience" away from the paparazzi.

As a result, the Springsteen kids partly grew up on an East Coast farm. Spingsteen developed an interest in horseback riding, and the rest is history.

Here's a look at the life of Jessica Springsteen:

The US Marine Corps sent a massive amount of Marines to Thailand for the annual Cobra Gold military drill, an exercise that has been held in Thailand almost every year since 1982.

The exercise was originally intended to strengthen relations between the US and its oldest ally in South East Asia, but has since turned into a drill for multiple nations in the region. This year, 11,075 personnel from 29 countries will participate.

The US nearly doubled its own contribution to the exercise this year, with 6,800 personnel participating. The increase is likely due to the threat of a more powerful China.

"This exercise is the largest multilateral exercise in the Indo-Pacific region. It speaks to the commitment of the US in the region," Steve Castonguay, a spokesman for the US Embassy in Bangkok, said.

Take a look at the awesome photos from the exercise here:

Starting a smart home is a fun endeavor, but it can also get expensive. Fast.

That doesn't have to be the case, though, and with a little planning and the right products, it's possible to create a smart home on a budget. 

The four products on this list all cost under $100, and when used together can make your current home smarter without a lot of extra work.

SEE ALSO: I've written about a bunch of great smart-home tech, but these are the gadgets I use every day — here's why

A smart-home hub

Every smart home needs a hub. 

A hub is how you communicate to all of your smart-home accessories, and in the case of Amazon's Echo Dot I mean that literally. 

As someone who uses an Echo product every day, I can attest to the platform's versatility, and being able to control parts of my apartment using my voice still impresses me.

The Echo Dot is just as smart and capable of any other member of the Echo family, but it's smaller and less expensive. If you're starting a smart home on a budget, this is the hub I'd choose.

Echo Dot, $49.99, available at Amazon

Smart plugs

Making the appliances you currently have smarter is significantly less expensive than buying all new ones. 

TP-Link's Smart Plugs make retrofitting these still-functional pieces of your home easy. You plug the smart plug into an outlet, connect it to your Wi-Fi and Echo (a process that doesn't take more than a couple of minutes), and plug in your "dumb" appliance. 

You'll be able to turn the appliance on and off through TP-Link's app or the Echo Dot, which doesn't make it as smart as a new appliance, but does make it more useful.

Think about your morning routine: There's probably something you have to turn on in another room, like a coffee maker. Wouldn't it be nice to turn it on and have fresh coffee waiting when you're done getting changed? That's the type of luxury smart plugs can provide while still being reasonably priced.

TP-Link Smart Plug Mini, $24.99, available at Amazon

Smart light bulbs

Smart light bulbs are probably the first smart-home accessory people think of when considering starting one. 

It's fun to turn your lights on and off with your voice (trust me), but there's also a lot of utility in it. If you have a room where the light switch is in an inconvenient spot, it pays to be able to turn the lights on and off without it. 

I've tried a couple of different smart light bulbs, and both have specific pros and cons. TP-Link's option is less expensive, but isn't part of a larger ecosystem of lighting products. 

Philips Hue bulbs require a larger upfront investment, but are part of a series of different lights that can be used in different places around your house. Most of the initial cost comes from having to buy a Hue starter pack, which includes a hub. Once you have a hub in the house, you're able to buy different lights a la carte, and it becomes less expensive.

Either way, as someone who started their smart home with bulbs like these, I can highly recommend them.

We're just days away from Season 14 of "The Voice," debuting Feb. 28 on CBS with new judge Kelly Clarkson. As the premiere nears, we couldn't help but wonder what happened to all the past winners of the TV singing competition series.

Here, we take a look at the champs from season 1 through 12.

(We figure we'll give Season 13 winner Chloe Kohanski a moment to get used to her newfound fame before we start tracking her post-"Voice" career.)

Season 1: Javier Colon

After jumping ship from Universal Republic Records, Javier Colon signed on with Concord Music Group in 2014. He debuted his fourth album, "Gravity," in 2016 and went on to tour behind the album.

Last year, the self-described "acoustic soul" artist starred in "Big River: The Adventures of Huckleberry Finn" at Unquowa Repertory Theatre in Connecticut – his home state – and performed with Charleston Symphony Orchestra for Broadway Under the Stars in South Carolina.

Season 2: Jermaine Paul

Jermaine Paul's debut album, tentatively titled "Make Love Save The World," never came to fruition (it was supposed to drop in 2015), and it seems his career has stalled quite a bit.

However, the singer-songwriter has participated in some low-profile events like fundraisers and performances in smaller venues, including at The Theatre at North in Pennsylvania in December.

Season 3: Cassadee Pope

Country singer Cassadee Pope has maintained her share of the spotlight since her win. She and Chris Young received a Grammy nomination for the 2015 duet "Think of You"— making her the first "The Voice" contestant to receive a Grammy nod.

In 2016, she released the EP "Summer" and went on to sing the "Star Spangled Banner" at the Brickyard 400 NASCAR race and at an NFL game that year.

Last May, she split with BMLG records, and she signed on with Fusion Music in January.

As cryptocurrencies like bitcoin surge in popularity, so do scams.

As seen in the cryptocurrency subreddit, scammers have found a way to make their website addresses (URLs) look just like the authentic URLs of some popular cryptocurrency exchange sites, like Binance and Bittrex.

Unfortunately for the unsuspecting crypto trader, using your login credentials on a scam site can lead to theft of your cryptocurrency or your regular government-minted money.

Cautious cryptocurrency traders are absolutely right to look for that green "https" tag that usually comes before a website's URL in a browser address bar. That tag helps users identify if a website is legitimate or not. But they may want to have a closer look at the URL next time they sign into their cryptocurrency exchange. 

Check out how scammers can get by your defenses, even if you think you're being vigilant:

SEE ALSO: I've started to mine cryptocurrency, and it's surprisingly easy — but I'm still 8 months away from breaking even

Usually, you can tell if a website isn't legitimate if it doesn't have the green "https" that comes before a website's URL.

Reddit user "chrysotileman" posted a screenshot of a fake cryptocurrency exchange site "coinsmarkets.com." If you're vigilant, it's easy to spot that it's not a legitimate site or a legitimate entity running the site because it doesn't have the proper certification to show that's it's trusted.

What you're looking for is a green "Secure" and "https" before the website's URL address, which is a sign that the site and company obtained the proper SSL (secure sockets layer) certificates. Obtaining an SSL certificate shows that the company behind the site is trusted.

Coinsmarkets.com doesn't have either the green "Secure" or "https" before its URL address. Instead, it has a grayed out "Not Secure" and a regular "http" before the URL. 

Usually, scam sites are identified and taken down pretty quickly. If you try to visit coinsmarkets.com now, you'll be met with an error message.

But some scammers have found ways to display the green "Secure" and "https" in the website URL address, and they make an incredibly subtle change to the site's address.

At first glance, this URL for the popular cryptocurrency exchange Binance looks perfectly legitimate. You can clearly see the green "https" before the Binance website URL.

It isn't clear how scammers obtain an SSL certificate, which allows them to add that re-assuring green "https" to the front of the URL. At the same time, it's also pretty easy to get an SSL certificate from a less reputable certificate issuer. 

A closer look reveals small dots under each instances of the letter "n" in the word "binance," which shouldn't be there.

Those two dots under the Binance URL mean that you're not actually looking at or using the real Binance site. Instead, you're looking at a totally different site made by scammers to look nearly identical to the Binance site.

And since the site looks familiar and the URL checks out at first glance, unsuspecting users type in their login credentials, which can then be recorded by the scammers. Once they have your account login credentials, scammers can do whatever they want in your account, including stealing your cryptocurrency and even stored USD funds.

If you're planning a wedding, chances are you've done your fair share of research on US weddings.

You may have even outsourced your wedding research to some other countries, like England and France.

Australia, however, probably isn't on your radar.

But, as it turns out, right now is a pretty good time to start thinking about Australian weddings. Australia officially legalized same-sex marriage at the end of last year, and, for what it's worth, the country also offers some cool, unique wedding traditions.

It's not that Australian weddings are all that different from ones you may attend in the United States. Still, there are some interesting distinctions that clearly mark the divide between an American wedding from those down under.

Keep scrolling to see what they are.

Both parents walk the bride down the aisle.

According to Aide-Memoire, it is pretty common for both the mother and the father to walk the bride down the aisle during the wedding ceremony. In fact, mothers and fathers may occasionally walk their son down the aisle, too.

Wedding guests may participate in a unity bowl ceremony.

Australian weddings will sometimes have a ceremony called a unity bowl, according to BuzzFeed. The unity bowl is a tradition in which guests fill a bowl with small, colorful stones during the wedding ceremony.

According to My New Orleans, the stones may have different colors, which represent different qualities, attributes, and people. After the ceremony, the newly-married bride and groom receive the bowl filled with stones to remind them of the support they have from their friends and family as they embark on their marriage journey.

The bride and groom might receive a special Bible.

If a couple is Christian, they may receive a keepsake Bible from a family member. According to Bridal Cookie, some Australian weddings feature a ritual in which the family passes down a Bible that has belonged to them for generations is passed down to the newly-married couple for safekeeping.

These days, it's hard to keep all the Amazon Echo devices straight.

There's the Spot and the Dot, and the Show and the Look. There's the second-generation Echo, which is different from the original Echo, which is also different from the Echo Plus.

In short, it can get confusing. 

Amazon offers six Echo devices total, and they're available from $50 all the way up to $230. With so many different options and price points, it's hard to tell which device might be right for you. 

So whether you're looking to buy your first Echo, upgrade to a new device, or add to your smart speaker collection, here are the major similarities and differences between all six devices to help you device which one is right for you:

If you just want to dip a toe in the smart-speaker game: Echo Dot.

The Echo Dot is Amazon's gateway smart speaker. It's tiny, easy to use, and only costs $50 (and it's often on sale for even less than that).

The Dot can do many standard smart speaker tasks, like play music, make calls, order products from Amazon, and control your smart home devices. 

But the Dot doesn't have a very powerful speaker, so it's not a great solution if you're just looking for a solid Bluetooth speaker.

And while it can easily be a standalone device, it also works great when combined with a full-size Amazon Echo — you can have your Echo live in one room, and place Echo Dots in other rooms throughout your house. 

If you want the device that does it all: Amazon Echo.

The Echo is the first mainstream — and arguably most successful — smart speaker you can buy. The device launched in 2014, and has since helped Amazon dominate the smart-speaker game — as of September 2017, analysts estimated that Amazon owned 76% of the smart-home market. 

Three years after launch, the Echo was due for an upgrade. So in September, Amazon revamped the original Echo, introducing a second-generation version with new finishes and a reduced price tag of $100. 

The new Echo has dual speakers, so it's a good option for playing music. With the new device, Amazon introduced multi-room audio, so you can play music from several Echo devices at once across rooms. The new Echo also has a powerful built-in Alexa, so it can also make calls, check the weather and traffic, request an Uber, or turn down the heat.

The original Echo does it all, and it's likely the best option for most people. 

If you're ready to start a smart home: Amazon Echo Plus

With more and more smart-home products coming online, it can be overwhelming to try to control them all. Enter the Amazon Echo Plus, which acts as a smart-home hub.

The Echo Plus, as its name denotes, is taller than the standard Echo, and costs $50 more at $150. But it can do many of the same things, like play music, send messages, and give you a daily news briefing. 

What sets the Plus apart is its ability to control other "smart" devices. You can say, "Alexa, discover my devices," and it will find anything else online, like smart light bulbs or locks, and set them up for you. Plus, you'll be able to give the device a single voice command to control multiple actions from multiple devices at once.  

Other Echo devices control your smart home, too, but the Echo Plus lets you integrate everything into one place with no need to download any of the "skills" you'd need to operate those features on the standard Echo. 

The National Rifle Association represents less than a fifth of all American gun owners, yet it remains one of the most powerful gun rights lobbies in the United States.

For decades, the NRA has successfully blocked federal action — including government-funded gun violence research and a proposed assault weapons ban— that it believes threatens gun owners' second amendment rights.

The NRA spends millions influencing Congress and the White House to advance its agenda. And its monetary prowess is still growing.

The group spent more money lobbying for expanded gun rights through the first two quarters of 2017 as it did in all of 2016. Last year's lobbying total surpassed $5.1 million, according to the Center for Responsive Politics' database.

The NRA was founded in 1871, but didn't begin to seriously influence policy until about a century later. Following the passage of the Gun Control Act of 1968, the NRA became much more politically active, establishing a Political Action Committee aimed at supporting gun-rights politicians over those advocating for gun control.

In 1977, it significantly grew and began to align with conservative members of Congress to push for more relaxed gun regulations, harnessing the grassroots power of its members across the country.

Today, the gun control debate is fraught with divisiveness and partisanship, especially after mass shootings like the one at a Florida high school that left 17 dead.

Many gun control advocates blame the NRA's aggressive lobbying tactics and dramatic rhetoric for driving Americans' opinions on the issue apart, but the group says its mission is to "protect and defend the Constitution of the United States."

While there are some gun-related issues on which a majority of Americans agree, the NRA's influence remains a contentious and dominant aspect of the ongoing gun debate. Here's how powerful the group really is:

DON'T MISS: New poll shows the American public could be at a turning point on gun control

While the cigarette, pharmaceutical, and insurance industries spend far more, the NRA spends nearly 10 times as much as the biggest gun control lobbying group in the country.

The NRA is especially active during presidential campaigns, contributing millions to candidates that support expanded gun rights and targeting those who threaten to control or regulate guns. In the 2016 election, the group threw its support behind President Donald Trump, and against Democratic opponent Hillary Clinton.

The NRA also contributes tens of thousands of dollars to Congressional candidates and members of both parties, though the lion's share goes to the GOP. The top 81 members of Congress with the most career NRA contributions are all Republicans.

7. Tufts University

Annual tuition fee: $54,318

National ranking: No. 29

Tufts University’s undergraduate population of 5,508 might be small, but its tuition fees are not. U.S. News puts the cost at $54,318 per year.

Despite its high price tag, Tufts only gives need-based financial aid to about 36% of its student body.

That said, the school’s need-based grants are sizeable. The average need-based award at Tufts is $41,366, an award that could go a long way toward helping you cover its sky-high tuition costs without taking out private student loans.

6. Franklin and Marshall

Annual tuition fee: $54,380

National ranking: No. 39

A small liberal arts college in Lancaster, Pennsylvania, Franklin and Marshall traces its 1787 founding back to Benjamin Franklin. Although Franklin’s donation of 200 pounds was enough to start the college, today’s students must pay a good deal more to attend.

Fortunately, Franklin and Marshall pledges to meet 100% of students’ financial need with aid in the form of grants, work-study, and low-interest student loans. About 54% of students received financial aid in 2017, and the average award totaled $42,719, reported U.S. News.

5. Trinity College

Annual tuition fee: $54,770

National ranking: No. 44

Of Trinity College’s 2,259 undergraduates, nearly one-half receive some form of need-based financial aid. Trinity offers a combination of grants, loans, and work-study to help students cover tuition.

If you’re part of the 34% of applicants accepted to this small college, you’ll enjoy a low professor-to-student ratio of 9-to-1. But you’ll have to cover $54,770 per year in tuition, along with an additional $14,200 for room and board if you want to live on campus, according to U.S. News.

Presidential rankings tend to be subjective and divisive, but they also provide valuable insight into how historical views of presidents evolve over time.

In a recent survey, nearly 200 political science scholars ranked US presidents on a scale of 0-100, from failure (zero) to average (50) to great (100). The totals were then averaged for each president and ranked from highest to lowest.

A majority of the 170 respondents — roughly 57% — identified as Democrats. Just 13% were Republicans, while 27% said they were independents, and 3% selected other. The skewed sampling plus the fact that President Donald Trump is in the middle of his second year in office make it difficult to accurately compare him to previous presidents.

But even among Republicans, Trump was ranked quite unfavorably. Respondents who identified as Republicans or conservatives ranked Trump 40th out of 44 presidents. Self-described Democrats and liberals both ranked him last.

Here are the greatest US presidents, ranked according to current and recent members of the American Political Science Association:

• Walmart heiress Alice Walton is the richest woman in the US — and the world. 
• With an estimated net worth of $47.9 billion, she ranks 13th on the Forbes 400.
• Alice Walton spends her vast fortune collecting art and breeding horses. 

Alice Walton, the only female heiress to the Walmart fortune, is not only the richest woman in the US.

She's also the richest woman in the world. 

The 68-year-old has a fortune worth $47.9 billion, according to Bloomberg. That's nearly $4 billion more than the second richest woman in the world — French heiress of cosmetics giant L'Oreal, Françoise Bettencourt-Meyers.

Previously the richest woman in the world, Bettencourt-Meyers inherited the family's fortune following the death of her mother, Liliane Bettencourt. Her net worth currently stands at $44.1 billion. 

The three Walmart heirs — Rob Walton, Jim Walton, and Alice Walton — have a combined wealth of $145.5 billion. That's about $50 billion more than the second richest family in America, the Kochs, according to Bloomberg data.

Despite the Walton's high status, their personal lives remain largely private. Scroll through to find out what we know about how America's richest woman spends her fortune, from collecting expensive art to breeding horses.

Unlike her brothers, Rob and Jim, Alice has never taken an active role running Walmart and has instead become a patron of the arts. She fell in love with the arts at a young age. When she was 10, she bought her first work of art: a reproduction of a Picasso painting for $2.

She has an immense private art collection, with original works from legendary American artists, Andy Warhol, Norman Rockwell, and Georgia O'Keefe.

Alice opened a $50 million museum called Crystal Bridges in 2011 to house her $500 million private art collection. When it opened, it had four times the endowment of the famous Whitney Museum in New York.

Day One

7:30 p.m. — "I, Tonya" was an interesting movie but I wouldn't see it again. When I told my mom I went, she said she wouldn't see it either because she "lived through it." After the movie, I decided to join the theater's movie club. My friends back home make fun of me, but it is a great deal: $8/month for one movie per month. (Tickets are otherwise $15!) You also get additional tickets for $8. $15

Day Two

10:30 a.m. — Parking is a disaster where my friend lives. I think I circled the block by her place four or five times before giving up and just driving farther away to find a spot. I walk toward what I think is her street, but realize I'm not by her place at all. I give in, call a Lyft, and pick her up so we can go to Neiman Marcus in Union Square. My friend and I both use Rent the Runway Unlimited's subscription service (and RTR is located on the top floor of Neiman). Since I've moved, I have significantly fewer social and work events to go to, so I generally use it for getting nice work clothes or when I travel. $10

12:30 p.m. — My friend pays for a Lyft over to the Marina/Wharf area where we are picking up rental bikes. We end up grabbing a late lunch at Buena Vista, the home of the original Irish coffee! We share a table with a couple and end up in conversation. One half of the couple is moving here from Seattle in a few months, and she is in town trying to figure out what neighborhood she wants to live in. We have fun exchanging moving to the Bay Area stories. $25

Day Three

4 p.m. — After what feels like the laziest day, full of binge-watching Divorce, I make it to my gym's Sunday afternoon yoga class. It's definitely not the best yoga class, and it drives me crazy when people show up late. But I enjoy the stretching and time for mental clarity — and that the class is included in my membership! 6 p.m. — Quick trip to Sprouts, which I've recently discovered. I have been a loyal Whole Foods shopper but their parking situation is ridiculous, and it's never difficult to park at Sprouts (and it's closer to my house). I grab a few things for the week and am in and out rather efficiently. $24

• With all of the national parks and natural wonders that the US has to offer, some of the best views are greatly underrated. 
• Portland Head Lighthouse, located in Port Elizabeth, Maine, is said to have been the inspiration for one of Henry Wadsforth Longfellow's poems. 
• Na Pali coast in Kauai, Hawaii, can be enjoyed by helicopter, boat, small plane, or an 11-mile hike.

Quick: close your eyes and picture a beautiful view.

Where do you put yourself? Looking out over tall, gleaming urban spires? Mammoth snowcapped peaks? Vast gashes in the earth?

Fortunately, no matter what your vision might be, you can probably find a view to match it somewhere in the US Inspiring vistas are ubiquitous and easy to find — they stretch from Hawaii to Maine.

Still, in our search for America’s best views, it was only natural to draw heavily from beautiful sites in the National Park system. Of course, we’re not alone in our desire to experience and celebrate views inside these protected areas: in 2015, more than 305 million people sought inspiration in America’s national parks, including some 15 million who witnessed the iconic views in California’s Golden Gate National Recreation Area.

But the best views in America don't only showcase national parks — they incorporate the magic twinkle of city skylines, the fortitude of rocky coastlines, and breathtaking discoveries found on easy walks, rugged hikes, and scenic drives across the nation. Anyone who’s experienced the dramatic drops around Big Sur, California, or basked in the glimmer of New York City’s skyline will certainly agree.

And uplifting views don’t necessarily start with tall buildings or plunging cliffs. Just ask anyone who’s witnessed the 360-degree panorama of nighttime lights on the National Mall in Washington, DC.

Fortunately, the best views in America aren’t going anywhere. From canyons and coastlines to peaks and parks, Americans have a proud history of preserving their special places for future generations.

But that doesn’t mean you should wait to see them. Put these gorgeous spots on your bucket list and start making travel plans.

Sunrise Point

The otherworldly landscape of Bryce Canyon’s towering sandstone hoodoos, natural arches, staircases, and canyons leaves an indelible impression no matter where you stand. Sunrise Point has incomparable views of the fire-hued, mostly limestone rock formations, which are the remnants of an ancient lake that covered western Utah. Visitors can take an easy hike from Sunrise Point to wander among the hoodoo giants along Queens Garden Trail.

Insider tip: Unfortunately, the hoodoos are eroding (at a rate of two to four feet per 100 years), so see them while they’re still at maximum height. The park also offers nighttime hikes, stargazing, and ranger-guided rim walks.

Battery Spencer

The perfect place to gaze at the Golden Gate Bridge is Battery Spencer at Fort Baker in Marin County. Located on a 335-acre, former 1905 US Army post, the splendid lookout is easily accessible by car or bike.

Insider tip: On a clear day, walk at least halfway along the bridge's pedestrian path for views of Alcatraz.

National Mall

The best advice for any first-time visitor to the nation’s capital is to start with a tour of the monuments on the National Mall — at night, when the marble structures resemble white beacons against a dark sky. There’s no more patriotic experience than to walk up the steps of the Lincoln Memorial and see the powerful marble statue of Honest Abe in his chair next to the engraved words of his Gettysburg Address. From there, looking out over the Reflecting Pool, is the towering Washington Monument, with the ornate dome of the US Capitol in the distance.

Insider tip: Find a National Park Ranger for a free — and incredibly knowledgeable — tour of the Mall and other monuments and historic sites.
