The U.S. is home to 61 national parks, and each one has something special about it. If you're pressed for time, though, you may want to turn your attention to the 10 most popular parks. These destinations saw the highest attendance of any national park in 2018, according to a list compiled by the National Park Service. From Acadia to Zion and the Rockies to the Smokies, here are just some of the factors that make the 10 most-visited parks so unique.

1. Great Smoky Mountains National Park is the salamander capital of the world.

Location: Western North Carolina and Eastern Tennessee
Total visitors in 2018: 11,421,200

This sprawling national park in the Smokies might be the most visited because it's also one of the most accessible, considering that it's located roughly within a day's drive of one-third of the U.S. population. The biodiversity is also undoubtedly a draw. Great Smoky Mountains National Park has been dubbed the "salamander capital of the world," and it's home to 30 different species of "spring lizard," as they're called in Appalachia, including the largest one in North America—the hellbender.

2. Grand Canyon National Park visitors could see a sea of clouds.

Total visitors in 2018: 6,380,495

Everyone knows the Grand Canyon, and for good reason—but did you know that its drastic landscape is capable of influencing the weather? Sharp changes in elevation mean that different parts of the park experience totally different weather conditions. North Rim is the coldest, wettest area in the region at an elevation of more than 8200 feet, but just 8 miles away lies Phantom Ranch, the hottest and one of the driest areas at 2460 feet. If you’re lucky, you may be able to witness a rare weather phenomenon called "total cloud inversion," which sometimes occurs at the Grand Canyon when cool air gets trapped beneath a layer of warm air creating a virtual sea of clouds.

3. Rocky Mountain National Park has the highest continuous paved highway in the U.S. running right through it.

As the third most-visited park in the U.S., Rocky Mountain sees a lot of foot traffic. Visitors can also drive along the scenic Trail Ridge Road, which has been called the "highway to the sky" because it soars two miles above sea level at its highest point. This 48-mile strip connects Grand Lake and Estes Park and delivers unparalleled views of the forests, tundra, and meadows below.

4. Zion National Park has its very own "Subway."

Location: Southwest Utah
Total visitors in 2018: 4,320,033

Only the adventurous can traverse The Subway in Zion National Park. To get to this tunnel carved out of rock, visitors must hike for 9 miles (round-trip), scramble over boulders, climb down waterfalls, and swim through creeks—"and the water is cold," according to Utah.com. The tubular landmark not only looks like a subway tunnel, but it also sounds like one, with the rushing water resembling the roaring sound of a subway as it pulls up to the station.

5. Yellowstone National Park once had a "bear lunch counter."

Total visitors in 2018: 4,115,000

Hungry black and grizzly bears used to feast on trash at an open-air dump in Yellowstone. These "bear shows" were a popular tourist activity between 1890 and the 1940s, and the park eventually installed wooden bleachers for spectators and a sign that read "Lunch Counter—For Bears Only." Unsurprisingly, this set-up was a recipe for disaster. Several park visitors were injured, and the feeding grounds ultimately closed to the public during World War II. The dump itself was shuttered in the '70s, and all waste is now removed from the park.

6. Yosemite National Park's "Firefall" was a huge spectacle for nearly a century.

Location: Central California
Total visitors in 2018: 4,009,436

In 1872, a local hotel owner by the name of James McCauley tossed campfire embers over the top of Yosemite's Glacier Point, inadvertently creating a cascading "firefall" that looked pretty spectacular from a distance. Thus, a tradition was born, and each summer evening at 9 p.m. sharp, someone would shout "Let the fire fall!" before pushing embers over the edge. These shows were banned from 1913 to 1917, and again during World War II, but they weren't officially eliminated until 1968. The National Park Service said the man-made attraction was better suited to Disneyland than the natural world, and reasoned that the huge crowds also damaged local meadows.

7. For part of the year, Acadia National Park's Cadillac Mountain is the first place in the U.S. to see the sunrise.

Location: Maine's Mount Desert Island
Total visitors in 2018: 3,537,575

If you want to be the first person in America to see the sunrise, visit the top of Acadia's Cadillac Mountain between October 7 and March 6. The 1528-foot peak is the highest point along the North Atlantic, making it a great vantage point to watch the Atlantic Ocean's glistening waters as they're bathed in sunlight. At other points in the year, the first sunrise can be viewed from either West Quoddy Head or Mars Hill, both of which are also in Maine.

8. Grand Teton National Park's name is a reference to boobs.

Location: Northwest Wyoming
Total visitors in 2018: 3,491,151

To 19th-century French-Canadian fur trappers, three of the highest mountain peaks in what is now Grand Teton National Park apparently looked like the female form. They called them les trois tétons, which translates to "the three breasts" or "the three teats." It's believed that the trappers were referring specifically to Grand Teton, Teewinot Mountain, and Mt. Owen. At any rate, the name stuck and was later anglicized.

9. Olympic National Park is home to one of the world's few temperate rainforests.

Total visitors in 2018: 3,104,455

Temperate rainforests can be found in just a few places around the world, including Chile, New Zealand, Australia, and America's Pacific Northwest. Thanks to all the moisture coming from the nearby Pacific Ocean, swathes of Olympic National Park are a lush oasis of mosses, ferns, lichens, and Sitka spruce.

10. Glacier National Park has some residents who love visitors: the mountain goats.

Total visitors in 2018: 2,965,309

Mountain goats are perfectly at home along the rugged terrain of Glacier National Park. They can scale slopes at a 60-degree angle and withstand temperatures as low as -50 degrees Fahrenheit, plus winds of 100 mph. (Confusingly, though, they're not actually goats at all. Rather, they're more closely related to gazelles and African antelope.) If you want to see these nimble mascots of Glacier National Park, you can head to Goat Lick Overlook, where the animals come to lick the salty, mineral-rich cliffs. Or, just go about your merry way and you'll surely see a few—the Glacier goats have learned that staying in the general vicinity of humans keeps them safer from predators.

12 Facts About Netflix, Recommended For You

Netflix has become the world’s intravenous line for filmed entertainment. And like any media empire, it has a few stories of its own to tell. Take a look at some lesser-known, non-buffering facts about the streaming giant.

1. Early Netflix subscribers got a lot of Chinese pornography.

In 1998, Netflix was still in the business of selling as well as renting DVDs. To try and offer consumers something new, co-founder Marc Randolph decided to offer footage of President Bill Clinton’s Grand Jury testimony about his involvement with Monica Lewinsky. But according to the book Netflixed, the duplicating house had a mix-up: out of the 1000 customers who ordered Clinton's interview, a few hundred received discs full of hardcore Chinese pornography.

2. Netflix was originally called Kibble.

Choosing a name for the company was a drawn-out process. Directpix.com, Replay.com, and other names were considered; so was Luna.com, which was the name of Randolph’s dog. When the company was being incorporated, he named it Kibble.com until they could decide on something permanent.

3. Netflix executives used to make house calls.

From the beginning, Netflix has been preoccupied with seeing how users interact with its software in order to select titles. In the late 1990s, subscribers near the company’s location in Los Gatos, California were reached via telephone and asked a series of questions. Then staffers would ask if they could stop by to watch them use the site. Surprisingly, most agreed. Netflix brought them coffee, a small investment for gaining valuable information about their usage.

4. Netflix got Dennis Quaid to sing.

For a 2006-2007 publicity tour, Netflix decided to screen films in thematically-correct locations: For example, Field of Dreams was shown in the “real” Iowa cornfield-slash-baseball diamond featured in the movie. But the company also wanted actors to make appearances. Their approach: offer to let those with bands perform for the crowds. Kevin Costner, Bruce Willis, Dennis Quaid, and Kevin Bacon all agreed to the barter deal. Quaid and his band, The Sharks, played in New Orleans before a screening of his film The Big Easy.

5. Netflix has made a science out of spoilers.

Because so much of Netflix’s high-profile content can be “binged” in a single weekend, the company commissioned cultural anthropologist Grant McCracken to examine how spoilers affect a person’s viewing habits. McCracken identified classifications of spoiler-prone people by whether they ruin a plot twist intentionally or hold it over others. (Some people are “Coded Spoilers,” too self-aware to let anything slip. These people are your friends.) His verdict? Some people enjoy the power they get from having knowledge of spoilers. But if a show is good enough, knowing about key scenes won't dissuade viewers from watching.

6. Netflix staffers think you decide on a movie in two minutes.

Netflix spends more than $150 million on improving their recommendation system every year, trying to arrange selections based on what they think you might like. That kind of personalized menu is necessary: The company estimates that users spend only two minutes browsing for a title before choosing one or opting for another diversion entirely.

7. Netflix staffers also think you might be kind of a liar. 

You can stop trying to impress Netflix with the streaming version of keeping Ulysses on your coffee table. In a 2013 WIRED interview, Carlos Gomez-Uribe—the company's vice president of product innovation from 2010 to 2016—noted that viewers often report viewing documentaries or esoteric foreign movies. “But in practice,” he said, “that doesn’t happen very much.”

8. the first "netflix original" was an abstract test footage short.

In order to test frame rates and how their streaming service handles different kinds of content, Netflix produced 11 minutes of test footage in 2011 that can be viewed by typing “example show” in their search engine. Cut together (as seen above), the shorts become a very strange, very abstract art film, with an unidentified man juggling and reciting Shakespeare. (But not, sadly, juggling while reciting Shakespeare.)

9. Netflix binge-watching might correlate with depression. 

A 2015 study by the University of Texas found that respondents who claimed to binge Netflix shows were more likely to suffer from depression, lack of self-control, or loneliness. The good news? The sample group was small—only 316 people—and the university’s definition of “binge-watching” was as low as two episodes. Amateurs. 

10. There’s a secret Netflix menu.

No, not that kind of secret menu. Pressing Shift + Alt + a left mouse click brings up a troubleshooting menu that allows you to adjust the bit rate of a stream so it doesn’t buffer. (On a Mac, it's Shift + Option + click.) The picture quality won’t be as good, but it’s better than a pixelated Demogorgon.

11. There was once a glitch in the Netflix matrix. 

In 2014, Netflix’s content descriptions became odd amalgamations of two different titles to create one completely nonsensical listing. The summaries were quickly fixed, but not before someone took several screen shots of the mishaps.

12. You'll soon be able to stream Netflix in a Tesla.

In July 2019, Tesla founder Elon Musk informed Tesla owners they would soon be able to stream both Netflix and YouTube in their cars, an attractive option for anyone looking to keep passengers occupied. But there's a catch: The services only work when the cars are parked. The feature will be available in newer-model cars at a date to be determined.
