How many national parks in the USA are there? The short answer is 63. That is the number of places officially designated as national parks by Congress and managed by the National Park Service. But the full story is even more impressive, because those 63 parks are only part of a much larger system that protects more than 85 million acres of American land.
If you have ever stood at the edge of the Grand Canyon at sunrise, watched Old Faithful erupt in Yellowstone, or hiked beneath the giant sequoias of California, you already understand why Americans call these places “America’s best idea.” In this guide, we answer the question in full, explain the difference between a national park and the wider National Park System, and highlight the parks every traveler should know.
How Many National Parks Are in the USA: The Official Count
As of today, there are 63 national parks. The most recent addition is New River Gorge National Park and Preserve in West Virginia, which was redesignated as a national park in December 2020. Before that, Indiana Dunes became the 61st national park in 2019, and White Sands in New Mexico became the 62nd later that same year.
The number changes only when Congress passes a law creating a new national park or redesignating an existing protected area. That is why the count has grown slowly over the decades. Each new park must meet strict standards for natural beauty, unique features, and national significance.
It is worth noting that the count of national parks is sometimes confused with the total number of units in the National Park System. The system as a whole contains more than 430 units, including national monuments, historic sites, recreation areas, seashores, and battlefields. Only 63 of those units carry the title “national park,” which is reserved for the largest and most spectacular landscapes.
The National Park System: Bigger Than the 63 Parks
The National Park Service manages 433 units across all 50 states, the District of Columbia, and several U.S. territories. Together, these sites cover more than 85 million acres. The system includes:
- 63 national parks
- National monuments, such as Devils Tower and the Statue of Liberty
- National historic sites and national historical parks
- National seashores, lakeshores, and recreation areas
- National battlefields and military parks
- National scenic trails and wild and scenic rivers
So when someone asks how many national parks in the USA exist, the answer depends on what they mean. If they mean places titled “national park,” the answer is 63. If they mean all protected sites in the National Park System, the answer is more than 430. Both numbers are correct in their own way, and both tell a story about how seriously America takes conservation.

The First National Park in the World
The story of America’s national parks began with Yellowstone. On March 1, 1872, President Ulysses S. Grant signed the law that set aside Yellowstone as a national park, making it the first national park in the world. At the time, the idea was revolutionary: land set aside not for a king or a private owner, but for the enjoyment of all people.
Yellowstone spans parts of Wyoming, Montana, and Idaho, and it is famous for its geysers, hot springs, and wildlife. Old Faithful, its most famous geyser, erupts roughly every 90 minutes. The park is also home to grizzly bears, wolves, bison, and elk, making it one of the greatest wildlife-watching destinations on the planet.
Other early parks soon followed. Sequoia and Yosemite were established in 1890, Mount Rainier in 1899, and Crater Lake in 1902. In 1916, President Woodrow Wilson signed the act creating the National Park Service, giving the growing collection of parks a single agency to protect and manage them.
Which States Have the Most National Parks?
California and Alaska lead the nation in national parks. California is home to nine national parks, including Yosemite, Joshua Tree, Death Valley, and Sequoia. Alaska has eight, including Denali, Glacier Bay, and Wrangell-St. Elias, which is the largest national park in the country at more than 13 million acres.
Utah follows with five parks, often called the “Mighty Five”: Arches, Bryce Canyon, Canyonlands, Capitol Reef, and Zion. Arizona has three, including the Grand Canyon, one of the most visited parks in the system. In total, about half of the states have at least one national park, while others, like Delaware, have none.
Size varies enormously. Wrangell-St. Elias in Alaska is larger than Switzerland. At the other end of the scale, Hot Springs National Park in Arkansas is the smallest, covering less than 6,000 acres around its famous thermal springs.
The Most Visited National Parks in the USA
Every year, hundreds of millions of people visit the National Park System. The most visited national parks consistently are:
- Great Smoky Mountains National Park, on the border of Tennessee and North Carolina, which draws more than 12 million visitors a year
- Grand Canyon National Park in Arizona, with its mile-deep gorge carved by the Colorado River
- Zion National Park in Utah, famous for its towering sandstone cliffs and Narrows hike
- Yellowstone National Park, the world’s first national park
- Rocky Mountain National Park in Colorado, with more than 300 miles of hiking trails
Great Smoky Mountains is the most visited national park by a wide margin, partly because it charges no entrance fee and sits within a day’s drive of much of the eastern United States. It is also a UNESCO World Heritage Site and one of the most biologically diverse places in North America.
How a Place Becomes a National Park
Not every beautiful landscape can become a national park. The process usually begins with a site being studied for national significance. Congress may first designate it as a national monument or another type of unit. Years or even decades later, if the site proves outstanding for natural, cultural, or recreational value that can be enjoyed by the public and preserved for future generations, Congress can pass a law redesignating it as a national park.
The National Park Service looks for places with exceptional scenery, unique ecosystems, or important history. That high bar is why there are only 63 national parks, even though the country has thousands of beautiful places.
Some parks were once national monuments. The Grand Canyon, for example, was first protected as a national monument in 1908 before becoming a national park in 1919. Others, like Gateway Arch in Missouri, were redesignated from a memorial to a national park in 2018.
National Parks in the USA: Natural Wonders Worth the Trip
Each of the national parks protects something found nowhere else. Here are a few standouts every American should see at least once:
- Yosemite National Park in California, home to El Capitan, Half Dome, and some of the tallest waterfalls in North America
- Grand Teton National Park in Wyoming, where jagged peaks rise above pristine alpine lakes
- Everglades National Park in Florida, a vast subtropical wetland and the only place in the world where alligators and crocodiles coexist
- Olympic National Park in Washington, which packs rainforest, mountains, and wild coastline into a single park
- Acadia National Park in Maine, where the sun first touches the United States each morning from the top of Cadillac Mountain
America’s parks also preserve human history. Mesa Verde in Colorado protects cliff dwellings built by the Ancestral Puebloans more than 700 years ago. At Gettysburg, the story of the Civil War is told on the battlefield itself.
Planning Your Visit to America’s National Parks
If you are planning a trip, a few tips will help you make the most of it. First, buy an America the Beautiful Pass if you plan to visit several parks. The annual pass covers entrance fees at all national parks and other federal recreation areas and pays for itself after just a few visits.
Second, book early. Popular parks like Yosemite, Glacier, and Rocky Mountain now use timed-entry reservation systems during peak season, and campgrounds fill up months in advance. Third, visit in the shoulder seasons of spring and fall when crowds are smaller and the weather is often at its best.
Finally, follow Leave No Trace principles: stay on trails, pack out your trash, keep a safe distance from wildlife, and never feed animals. The parks belong to all of us, and keeping them pristine is a shared responsibility.
America’s frontier spirit lives on in its parks, and the spirit shaped the history of the American cowboy, who roamed many of the same wide-open landscapes.
Why the Number of National Parks Matters
The count of national parks is more than a trivia question. It reflects a national commitment to protecting wild places in a rapidly changing world. Each park safeguards habitats, preserves clean air and water, and gives millions of people a chance to experience nature at its most spectacular.
National parks also support local economies. Gateway communities near parks depend on visitors who stay in hotels, eat in restaurants, and hire guides. Studies by the National Park Service show that every dollar invested in parks generates many more dollars in visitor spending.
Most of all, the parks remind Americans of something timeless: that some treasures are worth more untouched than developed. From the deserts of the Southwest to the glaciers of Alaska, the 63 national parks are the crown jewels of the American landscape.
