The history behind all 63 national parks in the US

People entered U.S. national parks nearly 312 million times in 2022, up by 15 million visits from the year before, according to the National Park Service. Eight of these federally-owned and protected parks garnered 26% of visits, and another 25% of visits came from the 331 least-visited parks.

President Woodrow Wilson first signed the “Organic Act” on August 25, 1916, creating the National Park Service. Since then, the service has helped safeguard so many of the nation’s scenic treasures with titles as varied as parks, preserves, reservations, fossil sites, and more. Stacker zooms in on national parks, and large land or water areas, typically larger than national monuments and more general than national preserves. Stacker used publicly available data and resources from the National Park Service to compile this brief history of all 63 national parks in the U.S.

Every national park is a natural or cultural resource the federal government deemed worthy of protection. Congress typically passes a statute to create a national park. Before that, each park passed a rigorous screening process to determine whether it is worth federal conservation. Researchers with the NPS have to deem the area of national significance, in other words, it is an unspoiled example of a resource that tells the story of U.S. natural or cultural heritage and history. Many of the older parks on this list, such as Acadia National Park, started as national monuments at the beginning of the 20th century, and later became national parks.

If you’re looking for your next outdoor adventure, the West Coast offers plenty of opportunities. California has nine. Arizona and Washington each have three, and Oregon adds one more to the list. But national parks are found throughout the nation and offer a wide range of sites and experiences.

Acadia National Park, Maine

Before Acadia became a national park, it was home to the Wabanaki people for 12,000 years. After colonization, European American settlers and tourists began to strain the infrastructure of the Maine islands that now make up the park. In 1916, wealthy landowners donated thousands of acres to the care of the government, and in 1929, the park was officially named Acadia National Park. Today, it’s one of the top 10 most visited national parks. NPS calls it the “crown jewel of the North Atlantic coast.

Arches National Park, Utah

If you’ve ever seen a picture of Arches National Park in Utah, it probably contained the Delicate Arch, the most popular feature of the park.

President Herbert Hoover first signed a proclamation to preserve the land in 1929, and the area officially became a national park in 1971.

Badlands National Park, South Dakota

Badlands National Park may have gotten its name from the original inhabitants of the land. The Lakota people called this part of South Dakota “mako sica,” which translates to “bad lands,” likely a reference to the terrain that makes living here difficult. Today, the national park is known for its many mammal fossils and for its clear views of the Milky Way thanks to the dark sky.
