Great Smoky Mountains heads the most visited national parks ranking for 2025, with 11.5 million visits, more than twice as many as Zion or Yellowstone.
This Finepedia guide, written in October 2026, ranks the ten national parks that drew the most recreation visits in 2025, using figures the National Park Service published in March 2026. Together the 64 national parks are only a small part of a park network that recorded more than 323 million visits in 2025, despite a 43-day partial government shutdown. For more on America's protected lands, see the Finepedia guides US States With the Most National Parks: Top 10 and Largest US States by Area: Top 10.
How We Chose These
We included only the 64 sites that carry the formal title of national park, leaving out parkways, memorials, seashores and recreation areas, even though some of those draw bigger crowds. The ranking uses recreation visits for calendar year 2025, the standard measure the National Park Service uses to count people entering a park for leisure. Figures come from the agency's 2025 visitation release and its statistics office, and we checked park details against park pages and Wikipedia. One person who enters a park on three different days counts as three visits.

1. Great Smoky Mountains Leads by a Huge Margin
Great Smoky Mountains National Park recorded about 11.5 million recreation visits in 2025, more than the next two parks combined. It straddles the border of Tennessee and North Carolina, within a day's drive of many large cities in the East. The park protects some of the oldest mountains on Earth and a rich mix of forest wildlife.
Key Facts
- Visits in 2025: 11,527,939
- Size: about 522,000 acres (2,114 km²)
- Highest point: Kuwohi, 2,025 m (6,643 ft), formerly called Clingmans Dome
- Entry: no entrance fee, though cars parked for more than 15 minutes need a parking tag
Did You Know?
Every year, for a few weeks around the start of June, the Elkmont area hosts a display of synchronous fireflies that flash in time with each other. The park is home to at least 19 species of firefly.
2. Zion Draws Crowds to a Narrow Canyon
Zion National Park in south-western Utah recorded almost 5 million visits in 2025, more than any other national park in the West. Most visitors head for Zion Canyon, a deep red-rock gorge carved by the Virgin River. Famous hikes include Angels Landing and The Narrows, where walkers wade up the river itself.
Key Facts
- Visits in 2025: 4,984,525
- Size: about 229 square miles (590 km²)
- Established as a national park: 1919
- Getting around: a free shuttle bus runs through Zion Canyon for most of the year
Why It Matters
Zion's canyon road became so congested in the 1990s that the park introduced shuttle buses in 2000 and closed the road to private cars for much of the year. That approach has since become a model for other busy parks.
3. Yellowstone Started the National Park Idea
Yellowstone National Park recorded about 4.8 million visits in 2025. Created by an act that President Ulysses S. Grant signed on 1 March 1872, it was the country's first national park and is widely seen as the first anywhere in the world. Most of the park lies in Wyoming, with smaller parts in Montana and Idaho.
Key Facts
- Visits in 2025: 4,762,988
- Established: 1 March 1872
- Famous sight: Old Faithful geyser
- Geothermal features: well over half of all the geysers on Earth
Did You Know?
Yellowstone sits on top of a giant volcanic hotspot, which heats the water that feeds its geysers, hot springs and mud pots. The park is also one of the best places in the lower 48 states to see bison, elk and wolves.
4. Grand Canyon Had a Difficult Year
Grand Canyon National Park recorded about 4.4 million visits in 2025, down from more than 4.9 million in 2024. On 9 July 2025, the Dragon Bravo Fire destroyed buildings on the North Rim, including the historic Grand Canyon Lodge. The South Rim, which normally receives about 90% of the park's visitors, stayed open.
Key Facts
- Visits in 2025: 4,430,653
- Established as a national park: 26 February 1919
- World Heritage status: listed by UNESCO in 1979
- Main feature: the gorge of the Colorado River
Why It Matters
The Grand Canyon exposes layers of rock spanning close to two billion years of Earth's history, which makes it one of the most studied landscapes in geology. Its 2025 dip shows how wildfires can change visitor numbers in a single season.
5. Yosemite Is Famous for Granite Cliffs and Waterfalls
Yosemite National Park in California's Sierra Nevada recorded about 4.3 million visits in 2025. Its valley is lined with huge granite walls such as El Capitan and Half Dome. Yosemite became a national park in 1890, and UNESCO added it to the World Heritage list in 1984.
Key Facts
- Visits in 2025: 4,278,413
- Size: about 1,187 square miles (3,070 km²)
- Wilderness: almost 95% of the park
- Tallest waterfall: Yosemite Falls, 739 m (2,425 ft)
Did You Know?
In 1864, decades before national park status, the valley and the nearby Mariposa Grove of giant sequoias were set aside for protection under a law signed by President Abraham Lincoln.
6. Rocky Mountain Has America's Highest Paved Through Road
Rocky Mountain National Park recorded about 4.2 million visits in 2025. It lies in Colorado's Front Range, roughly 90 km from Denver, with the Continental Divide running through its centre. Much of the park sits above the tree line, where alpine tundra covers the high ground.
Key Facts
- Visits in 2025: 4,171,431
- Established: 26 January 1915
- Trail Ridge Road: climbs to 3,713 m (12,183 ft)
- River source: the Colorado River begins inside the park
Why It Matters
Trail Ridge Road, built in the 1930s, lets visitors drive across the Continental Divide and into tundra that would otherwise take a long climb to reach. The road usually closes in winter because of deep snow.
7. Acadia Brings Mountains to the Atlantic Coast
Acadia National Park on the coast of Maine recorded about 4.1 million visits in 2025. It takes in roughly half of Mount Desert Island, close to Bar Harbor, along with parts of nearby islands and the Schoodic Peninsula. It is the only national park in the north-eastern United States.
Key Facts
- Visits in 2025: 4,079,318
- First protected: 1916, as a national monument called Sieur de Monts
- Highest point: Cadillac Mountain, 466 m (1,530 ft)
- Size: about 49,000 acres (199 km²)
Did You Know?
Acadia is the oldest of all the national parks lying east of the Mississippi. Its network of historic carriage roads, closed to cars, was paid for by the philanthropist John D. Rockefeller Jr.
8. Grand Teton Has Some of the Most Dramatic Peaks in the Rockies
Grand Teton National Park in Wyoming recorded about 3.8 million visits in 2025. Its jagged Teton Range rises sharply above the flat valley of Jackson Hole, with no foothills in between. The park lies only about 16 km south of Yellowstone, and many visitors see both on one trip.
Key Facts
- Visits in 2025: 3,800,648
- Established: 1929, and enlarged in 1950
- Highest peak: Grand Teton, 4,199 m (13,775 ft)
- Size: about 310,000 acres (1,300 km²)
Why It Matters
Together with Yellowstone and the forests around them, Grand Teton forms part of the Greater Yellowstone area, one of the largest nearly intact temperate landscapes left on Earth. It is a major refuge for elk, moose, pronghorn and grizzly bears.
9. Olympic Packs Three Landscapes Into One Park
Olympic National Park on Washington's Olympic Peninsula recorded about 3.6 million visits in 2025. It combines a wild Pacific coastline, glacier-topped mountains and some of the wettest temperate rainforests in the world. About 95% of the park is protected as wilderness.
Key Facts
- Visits in 2025: 3,584,187
- First protected: 1909, as Mount Olympus National Monument
- National park since: 29 June 1938
- World Heritage status: listed by UNESCO in 1981
Did You Know?
The park was first set aside by President Theodore Roosevelt in 1909 and made a national park under President Franklin D. Roosevelt in 1938, so two presidents with the same surname helped create it.
10. Glacier Is the Crown of the Continent
Glacier National Park in north-western Montana recorded about 3.1 million visits in 2025. Its land, over a million acres, runs along the Canadian border and holds more than 130 named lakes. Its best-known drive, Going-to-the-Sun Road, dates from 1932 and tops out at Logan Pass on the Continental Divide.
Key Facts
- Visits in 2025: 3,136,557
- Established: 1910
- Size: over a million acres (about 4,100 km²)
- Neighbour: Canada's Waterton Lakes National Park
Why It Matters
In 1932, Glacier and Waterton Lakes were joined as the first international peace park anywhere, a symbol of friendship across the border. The shrinking of its glaciers over the past century is also closely studied by scientists.
Frequently Asked Questions
Which National Park Service site gets the most visitors overall?
The Blue Ridge Parkway in Virginia and North Carolina had the most recreation visits of any site run by the National Park Service in 2025, about 16.5 million, followed by Golden Gate National Recreation Area in California. Neither carries the title of national park, so they are not in this list.
How many national parks does the United States have?
As of October 2026, the country has 64 national parks. California has the most, with nine. They are part of a much larger network of more than 400 sites run by the National Park Service.
Conclusion
The parks on this list range from misty Appalachian forests to desert canyons, geyser basins and Pacific rainforest. Great Smoky Mountains stays far ahead of the rest, while the parks from second to seventh are separated by less than a million visits.
