63 National Park Facts You Definitely Want to Know

Be sure to read to the end so you don't miss out on these jaw-dropping facts!

1. A remote Native American tribe lives deep inside the Grand Canyon National Park.

As a natural wonder of the world, the Grand Canyon is one of the most popular tourist attractions in America. But while most travelers only come for a quick visit, there is actually a community that lives full-time at the base of the canyon.

Within the Havasupai Indian Reservation, Supai Village has a population of 208 and is the most remote settlement in the lower 48. In fact, it's so off-the-grid that the mail has to be delivered by pack mule.

2. The 750-foot-tall dunes at Great Sand Dunes National Park actually sing.

This Colorado national park is home to the tallest sand dunes in North America, soaring about 750 feet in the sky. But the dunes have a special secret: They sing!

When there's an avalanche, the sand starts to hum deeply. This sound was the inspiration behind Bing Crosby's 1942 hit "The Singing Sands of Alamosa." If you want to see them for yourself, rent a sandboard or sled to zoom down the sandy slopes!

3. One of the waterfalls at Yosemite National Park looks like lava.

Horsetail Falls Surreal Places in the U.S.

At golden hour in mid- to late-February, Horsetail Fall in Yosemite National Park is transformed. The way the sun's rays hit the cascade, it looks like a fiery lava flow off the side of a cliff.

This is also a nod to the park's historic Firefall, which started in 1872 when the owner of the Glacier Point Hotel would throw campfire embers from the summit of Glacier Point every night (until the practice ended in 1968).

4. The fireflies at Congaree National Park put on a light display every summer.

boardwalk at the congaree national park

Congaree has the largest old-growth bottomland hardwood forest in the U.S. Even more phenomenal? For a month in early summer, between the end of May and the start of June, thousands of fireflies simultaneously light up each night at exactly the same time for a magical natural show.

5. Yellowstone's Hot Springs are so acidic, they can dissolve a human body overnight.

Grand Prismatic Spring Yellowstone national park

Yellowstone National Park is one of the most iconic in America—and also the world's first national park (established in 1872 by President Ulysses S. Grant). It has the largest number of mammal species, its own Grand Canyon, and half the world's hydrothermal features, including mud pots, geysers, and hot springs. The latter are so acidic, they can actually dissolve a human body overnight.

6. The "sand" at White Sands National Park isn't real—it's an optical illusion.

One of the newest national parks, White Sands, is nothing but an optical illusion. First off, it's not actually made of sand—it's a gypsum dune field (and the largest of its kind on the planet). The crystals reflect the sun, making them shimmer white to the human eye and feel cool to the touch.

And if you see some antelope crossing the ribbed dunes—that's not a mirage. In the 1970s, 95 African oryx were imported from the Kalahari Desert.

7. There's an underground lunchroom hidden 750 feet below Carlsbad Caverns National Park.

Carlsbad Caverns New Mexico magical caves in the united states

This 47,000-acre national park—which was once part of an ancient underwater reef—contains more than 120 caves beneath its surface. Although visitors in the early 20th century had to be lowered into the caves in a bucket, it is now very easy to access. So simple, in fact, that an underground lunchroom was built in one of the chambers 750 feet below ground.

8. Canyonlands hosts an annual Thelma & Louise half-marathon.

Key scenes from Thelma & Louise were filmed in this national park. Today, a Thelma & Louise half-marathon is run every year through the Canyonlands in honor of the 1991 classic.

9. North Cascades National Park was the inspiration behind two iconic Beat Generation novels.

Mt. Shuksan reflected in Picture lake at North Cascades National Park

For two months, author Jack Kerouac worked at this Washington national park as a Park Service fire spotter and lived in a cabin on Desolation Peak. He later used this experience as material for two novels, including The Dharma Bums.

10. One of President Lincoln's assassinators was imprisoned in the fort at Dry Tortugas National Park.

Dry Tortugas National Park Magical Destinations

Dry Tortugas National Park spans a series of islands some 70 miles from Key West. Its striking centerpiece, Fort Jefferson, is an unfinished coastal fortress that is the largest brick masonry structure in the Western hemisphere. During the Civil War, it served as a prison and had famous inmates such as Samuel Mudd, who was involved in President Abraham Lincoln's assassination.

11. Death Valley is the hottest place on the planet.

Death Valley National Park is famous for holding the record for the hottest place on Earth, where the temperature was recorded at 134 degrees in 1913. What people might not know, however, is that it's also the largest national park outside Alaska, with over 1,000 miles of roads to explore.

There's one fairly unusual activity you can participate in while you're here: fruit picking. The national park in Utah has 1,900 fruit trees, including apple, pear, peach, and cherry trees. Visitors are allowed to pick and eat the fruit from them—just weigh your bounty at the self-pay station.

13. Black Canyon of the Gunnison is so deep that sunlight only reaches the floor for 33 minutes each day.

Black Canyon of the Gunnison National Park in Colorado

Instead of being named after the color of its rocks—as one might think—this Colorado national park is called "Black Canyon" for the way the sunlight hits it. Because the canyon walls are 2,722 feet tall in the deepest part, the rays only reach the very bottom for 33 minutes each day.

14. Indiana Dunes National Park has more plant and animal species than the entire state of Hawaii.

indiana dunes national park lakeshore

This park on the shore of Lake Michigan may be known for its sand dunes, but it's also home to savannas, marshes, prairies, forests, swamps, and more within its 15,000 acres. In fact, it's actually one of the most biodiverse areas on the continent, with more plant and animal species than Hawaii.

15. The first female nature guides were trained in Rocky Mountain National Park.

In 1916, sisters Esther and Elizabeth Burnell first visited Rocky Mountain National Park. They loved it so much that they trained to become the first female naturalists certified by the National Park Service. After that, Esther snowshoed 30 miles across the Continental Divide, and Elizabeth spearheaded the park's trail school for more than a decade.

16. Acadia National Park is the first place to see the sunrise between October and March.

Acadia is home to the East Coast's tallest peak, Cadillac Mountain, which measures up to 1,530 feet. It's also the first place you can spot the sunrise in America from early October to March.

And that's not all! Acadia happens to be "the first national park created from private lands gifted to the public through the efforts of conservation-minded citizens," according to the National Park Service.

17. There are hundreds of centuries-old shipwrecks hidden underwater at Biscayne National Park.

Did you know that 95 percent of Biscayne National Park is located underwater? Here, you'll find no fewer than 44 documented shipwrecks, though there are hundreds more yet to be discovered.

Some date back to the 1500s, but only six of the wrecks have been mapped for divers to explore.

18. The Gateway Arch is double the height of the Statue of Liberty.

Gateway Arch in St. Louis MO

Usually, national parks are found in the wilderness, not in the middle of a city. But St. Louis' 192-acre Gateway Arch National Park is right in the heart of downtown, making it the country's smallest national park.

And there are some optical tricks at play here, too. Despite how it might look, the riverfront arch is exactly as wide as it is tall (630 feet). That is twice the height of the Statue of Liberty!

19. The oldest human bones in North America were found at Channel Islands National Park.

This group of five islands off the California coast—Anacapa, Santa Cruz, Santa Barbara, Santa Rosa, and San Miguel—is often referred to as the "Galapagos of North America" due to their endemic plants and plentiful wildlife. Beyond animals, the oldest human bones on the continent (dating back to 13,000 BCE) were found on Santa Rosa Island. These remains were named the Arlington Springs Man.

20. The California condors at Pinnacles National Park have a wingspan the length of a compact car.

Pinnacles National Park in California USA

A new addition to the United States' lineup of national parks (it was established in 2013), Pinnacles is one of the only places on the North American continent where you can see the endangered California condor—famous for its almost 10-foot wingspan—fly free.

21. The Hoh Rain Forest at Olympic National Park receives more precipitation every year than the Amazon.

This national park isn't somewhere you'll come for the weather. Its Hoh Rain Forest, one of the few remaining temperate ones in the U.S., receives up to 12 feet of precipitation each year. That's more than the average rainfall in the Amazon.

22. The observatory at Haleakalā National Park is located above one-third of Earth's atmosphere.

Hawaii's first astronomical observatory is located on the summit of Haleakalā, the park's eponymous volcano and Maui's tallest summit (10,023 feet tall). It's located above one-third of Earth's atmosphere, and thanks to its setting, it's one of the most significant observatories in operation.

23. One World Trade Center could fit underwater at Crater Lake National Park.

Crater Lake has some serious bragging rights. At 1,943 feet, it's the deepest lake in the U.S. (For comparison, One World Trade Center in New York City is 1,776 feet tall.) All of its water comes from snow or rain; there aren't any streams or rivers feeding into this freshwater marvel.

great smoky mountains national park

The Great Smoky Mountains have vast amounts of wildlife, but we bet you didn't know it was also considered the salamander capital of the world. In fact, more than 30 diverse species of salamanders live here.

And apparently, the world is full of fans because this area remains the most visited national park across the U.S.

25. The average visit at Isle Royale National Park is 21 times longer than all other national parks.

There's usually not a ton to do in national parks other than hiking. Not so with Michigan's Isle Royale. Here, the average visit time is 3.5 days compared to a four-hour visit on average for other national parks.

Wilderness camping is the name of the game, so backpackers have to bring everything they need for a few days of roughing it.

26. Mount Rainier was temporarily renamed in honor of the Super Bowl.

Mount Rainier National Park Magical Destinations

Mount Rainier is an iconic fixture behind Seattle's skyline. The city is so attached to it that the Washington State Senate temporarily renamed the national park "12th Man National Park" and the summit "Mount Seattle Seahawks" leading up to the Super Bowl XLVIII in 2014.

27. The Cliff Palace at Mesa Verde National Park is about as old as the Leaning Tower of Pisa.

Mesa Verde Cliff Palace

This park, which preserves the heritage of the area's ancestral Pueblo people, has no fewer than 5,000 archaeological sites—and those are just the ones that are known. The Anasazi lived here for 700 years (between 600 and 1300 CE).

28. Gates of the Arctic is the least visited national park, drawing a smaller number of annual tourists than the Grand Canyon sees in a single day.

Looking up the Dawn Creek drainage in Gates of the Arctic National Park, Alaska

Located completely above the Arctic Circle, Gates of the Arctic National Park is the northernmost national park in the United States. It also has no roads and few trails within its remote boundaries, which is another reason why it's the country's least visited national park.

In fact, less than 11,000 tourists made the trek to this Alaskan park in 2019—that's less than the average number of people that visit the Grand Canyon in a single day.

29. The country's designated Christmas tree can be found at Kings Canyon National Park.

Every Christmas, a special service is held around the base of the 3,500-year-old General Grant Tree in Kings Canyon National Park. This tradition started in 1925, and a year later it was designated the "Nation's Christmas Tree" by President Calvin Coolidge.

If you want to join the celebration, visit on the second Sunday of December for the annual "Trek to the Tree."

30. Three former presidents held a secret meeting at Shenandoah National Park.

Within this park's grounds is Rockfish Gap, smack in the Blue Ridge Mountains. There, a roadside tavern formed a meeting spot for three men who would later become American presidents: James Madison, James Monroe, and Thomas Jefferson.

Except this time, they weren't hanging out on government business—they gathered here to lay the foundation for the University of Virginia.

31. Glacier National Park has a special mountain goat-shaped passport stamp for those who try to cross the Canadian border.

It's also the only U.S. national park site south of the equator.

33. It takes up to a month to summit Denali.

Towering at 20,308 feet in elevation, Denali National Park contains one of the most challenging climbs in the country. In fact, the Alaskan expedition takes two to four weeks, and out of the 32,000 people who have attempted it, only half have succeeded.

Within that group are Barbara Washburn, the first woman to reach the summit in 1947, and 78-year-old Tom Choate, the oldest man to climb the peak in 2013.

It's also the world's most massive single mountain, with a density that's 19,000 cubic miles in volume.

35. Badlands National Park has had two names in its history.

Badlands National Park

The park's name goes back to the Oglala Sioux's ancestors, who called it mako sica, translated as "land bad." French-Canadian fur trappers later built on that title, calling it les mauvaises terres a traverser, or "the badlands to cross."
