Delicate Arch at Arches National Park


There are more than 2,000 natural sandstone arches inside the boundaries of Arches National Park. Landscape Arch is the largest and longest in North America, stretching 306 feet, the length of a football field. The big top rock at Balanced Rock is the size of 3 school buses! Check out more Arches National Park Facts!


The name Badlands comes from the Lakota, who first called it “mako sica”, or “land that is bad”. The lack of water, bizarre topography, and extreme temperatures in the Badlands National Park area were the likely reasons. In more modern geologic terms, “badlands” are simply an area of soft rock heavily eroded in an overall dry climate.

Big Bend

Floating the Rio Grande River, especially through Santa Elena Canyon, is a popular activity. Since the international border is officially in the middle of the river, these river excursions at Big Bend National Park are treated as international trips by authorities, and proper documentation (i.e. a passport) is required.


95% of Biscayne National Park‘s 173,000 acres are underwater. Other than the Convoy Point area near the visitor center, a boat is needed to access the park. Biscayne Bay is generally a very shallow sea, with an average depth of only 10 feet.

Black Canyon of the Gunnison

Some parts of the canyon receive so little sunlight that they look black, hence the very literal name “Black Canyon of the Gunnison”. The canyon is so narrow and so deep that sunlight only barely reaches parts of the gorge each day, about 33 minutes total.

Inspiration Point landscape at Bryce Canyon
Hoodoos at Bryce Canyon

Bryce Canyon

The Bryce Canyon National Park facts are all about geology. For millions of years water has carved Bryce’s rugged landscape. In about 50 years the present rim will be cut back another foot (30 centimeters). The erosional force at Bryce Canyon National Park consists of frost-wedging and the dissolving power of rainwater to shape the colorful limestone rock into bizarre formations including slot canyons, windows, fins, and spires called “hoodoos.”


The famous ending scene of 1991 “Thelma & Louise” was filmed above the Colorado River in Canyonlands National Park. “127 Hours,” starring James Franco, tells the story of Aron Ralston who got stuck in a slot canyon in the Maze District and had to self- amputate his arm to get free.

Capitol Reef

One unexpected feature that you wouldn’t expect to find in a national park is the Fruita Orchards. Planted by Mormon pioneers who settled in the region, these orchards are now open to the public. During harvest seasons at Capitol Reef National Park, you can even pick and eat the fruit, and take some home with you for a small fee.

Carlsbad Caverns

At present there are 117 known caves in the park. The Big Room in Carlsbad Caverns, at 8.2 acres, is the largest accessible cave chamber in North America. The caves in Carlsbad Caverns National Park are 56°F throughout the year, with high humidity.

Channel Islands

Channel Islands National Park encompasses five remarkable islands and their ocean environment. Isolation over thousands of years has created unique animals, plants, and archeological resources found nowhere else on Earth. There are only three mammals that are native to the islands: deer mouse, spotted skunk, and the Channel Islands fox.


Congaree National Park has the largest old-growth bottomland hardwood forest in the U.S. But the coolest event happens 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!

crater lake national park
Crater Lake National Park

Crater Lake

Crater Lake was formed by the fall of a volcano. At 1,943 feet deep, Crater Lake is the deepest lake in America. Famous for its beautiful blue color, the lake’s water comes directly from snow or rain, there are no inlets from other water sources.

Cuyahoga Valley

The 308-mile long waterway, the Ohio and Erie Canal, runs through the park and was dug by hand. Most of the workers were Irish and German immigrants. There are no drive-to campsites in Cuyahoga Valley National Park, but there are five campsites where cyclists and hikers can pitch a tent and stay overnight.

Death Valley

Death Valley National Park is the largest national park in the lower 48 U.S. states, stretching 5,300 square miles or 3.4 million acres. The highest recorded temperature in the world was recorded in Death Valley’s Furnace Creek at 134 Fahrenheit in July 1913. Death Valley is home to the country’s lowest point, Badwater Basin, which lies at 282 feet below sea level.


Denali is a true wilderness with only one road bisecting the park. Some of Denali’s park rangers walk on four legs. Sled dogs have been helping rangers patrol the park since it opened in the 1920s. They are the only sled dogs in the United States that work in a national park. Visitors can see sled dog demonstrations in the summer, view the dogs at work in the winter or visit their kennels year round.

Dry Tortugas

Located 70 miles from Key West in the Gulf of Mexico, Dry Tortugas National Park is a collection of seven tiny islands that can be reached only by boat or plane, making it the country’s most remote national park.

Everglades National Park


Visitors can explore Everglades National Park by canoe or kayak along hundreds of miles of water trails or bike through pine rocklands. For those who want even more adventure, experience a side of the Everglades that most people never see by joining a ranger-led hike called slough slogging where you’ll be waist-deep in the pristine Florida swamp.

Gates of the Arctic

Gates of the Arctic National Park is the most northern national park in the United States. All of the park’s 8,472,506 acres are north of the Arctic Circle. It is also the least visited national park in the United States most years. There are no roads within the park lands, and very few trails. The Dalton Highway passes just to the east of the park; some visitors hike in from there.

Gateway Arch

The arch’s two legs were built separately, and if their measurements were off by as little as 1/64th of an inch, they would not have been able to join at the top. The arch is as tall as it is wide, though it might not look like it. The Gateway Arch is 630 feet tall and 630 feet wide. Since you’re not always looking at the arch straight on, you experience an illusion that it’s much taller than it is wide.


Visitors to Glacier National Park can enjoy tours of the park in style in historic red buses called ‘Jammers.’ Originally introduced to U.S. National Parks in the 1930s in an effort to reduce car traffic, this distinctive fleet of coach cars was restored and modified in 2002, with a number converted to run on alternative fuel. Many repeat visitors to the park say their drive along Going-to-the-Sun Road in the vintage Jammer bus with the wind in their hair was the best part!

Glacier Bay

Glacier Bay National Park is larger than the U.S. state of Connecticut. At the same time, it is less than 1% of the total area of Alaska. It’s part of a 25-million acre World Heritage Site—one of the world’s largest international protected areas. The ice that breaks off, or calves, from the tidewater glaciers in Glacier Bay is between 75 and 200 years old.

Grand Canyon National Park
Grand Canyon National Park

Grand Canyon

There is actually a community that lives full-time at the base of the Grand Canyon. Within the Havasupai Indian Reservation, Supai Village has a population of 208 and is the most remote settlement in the lower 48 states. It’s so off the grid the mail has to be delivered by pack mule – wow!

Grand Teton

Earthquakes formed the 40 mile-long Teton Range found at Grand Teton National Park. The Tetons sit on a fault line, and over millions of years, earthquakes shook the land, causing blocks of land on both sides of the fault to slip past each other. The west block of land rose upward to form the mountains while the east block of land dropped down to form the valley called Jackson Hole. The Tetons are the youngest range in the Rocky Mountains and some of the youngest mountains in the world.

Great Basin

Some of the oldest trees on earth live on the craggy mountain slopes of Great Basin National Park. The rare Great Basin bristlecone pine grows in isolated groves near the tree line, where it can survive for 4,000 years or more under extremely harsh conditions. Much of the landscape at Great Basin National Park was carved by glaciers, and some of them are still here. The Lehman rock glacier – a large mass of boulders cemented together by ice – is visible from the Glacier Trail and the Summit Trail.

Great Sand Dunes

You’ll find Great Sand Dunes National Park in Colorado. It’s home to the tallest sand dunes in North America, soaring about 750 feet in the sky. There’s a little-known secret: the dunes sing! When there’s an avalanche of sand in the area, the sand starts to hum deeply. A fun activity here is to rent a sandboard or sled to ride down the sandy slopes!

Isle Royale National Park is the only major national park to close entirely for the winter because of the difficulty of travel and hazards of wilderness survival during Michigan’s winters.

Joshua Tree

The Joshua Tree is actually a yucca plant and is in the the same subgroup that includes flowering grasses and orchids. It grows primarily in the Mohave Desert, which includes Joshua Tree National Park. They are a slow mover, growing just 1-3″ per year. Based upon that growth rate, some researchers think that the average lifespan for the tree is 150 years.

The Katmai area is home to about 2,000 grizzly, or brown bears, the largest concentration known. People come from all over the world to visit Katmai National Park for the sole purpose of viewing bears. World famous Brooks Falls is the most popular place to view the bears. The Falls Platform has a limited capacity of 40 people, with limits of one hour at a time on the Falls Platform during the busy summer season.

Kenai Fjords

Kings Canyon

During World War II Kings Canyon National Park and Sequoia National Park began to be managed together as Sequoia and Kings Canyon National Park – as they adjoin each other and protect much of the same landscape and sequoia trees. Kings Canyon National Park features Kings Canyon, a glacial valley with cliffs, meadows, waterfalls, and a river. The canyon deepens outside the park making it North America’s deepest.

Kobuk Valley

Kobuk Valley National Park lies 25 miles north of the Arctic Circle, joining Gates of the Arctic National Park as the only two U.S. national parks north of that line. Kobuk River Valley has been an important caribou migration crossing for as long as 10,000 years. The caribou that pass through have been hunted to provide food, clothing, and other items important for survival of the people in the area for thousands of years. The only people allowed to hunt in Kobuk Valley National Park are the local residents.

Mammoth Cave

Mammoth Cave in Kentucky is the world’s longest known cave system, with more than 400 miles explored, and one of the oldest tour attractions in North America. UNESCO decided to officially protect Mammoth Cave National Park as a World Heritage Center in 1981, mainly due to the fact that almost every type of cave formation is present within the site.

Prior to being designated as a national park, part of Shenandoah National Park‘s land was farmland. Because of this there are cemeteries found within the park. After Shenandoah National Park was designated a national park, residents of the area had to move off the land. The exception was for elderly or disabled people. The last resident of the park was Annie Lee Bradley Shank, who died in 1979 at the age of 92.

Theodore Roosevelt National Park

Theodore Roosevelt

It’s fitting that the only U.S. national park to be named for a person is for Theodore Roosevelt. He established the U.S. Forest Service and created five national parks, 150 national forests, 51 federal bird reserves, four national game preserves, and 18 national monuments, totaling more than 230 million acres of protected land. Theodore Roosevelt National Park preserves tens of thousands of acres near his former Elkhorn ranch. “I never would have been President had it not been for my experiences in North Dakota,” he famously wrote.

Virgin Islands

Unlike the rest of the United States, in the U.S. Virgin Islands, vehicles drive on the left side of the road.

All water used is collected from the rain, or trucked in at very high prices.


‘Voyageur’ is a French word that translates to ‘traveler’ in English. The waterways that flow through Voyageurs National Park were extremely important to the fur trade in the late 1600s and 1700s. Visitors to the park can see evidence of Native Americans who once called the land home. As well as evidence of the fur traders and homesteaders who did logging, fishing, and mining activities in the area.

White Sands

The area is not actually made of sand—it’s a gypsum dune field (the largest of its kind on Earth). The crystals reflect the sun, making them shimmer white to the human eye and feel cool to the touch. In the 1970s, 95 African oryx were imported from the Kalahari Desert to White Sands National Park.

Yellowstone National Park (in Wyoming, Idaho, and Montana) is the oldest U.S. national park, founded in 1872. 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.


Three of the 10 highest waterfalls in the world are located in Yosemite National Park in California. Ribbon Falls in Yosemite is nine times taller than Niagara Falls. But one waterfall looks like lava one time each year! 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. 


One of the Zion National Park facts is about it’s name. It’s an ancient Hebrew word for sanctuary or refuge.
