The least-visited national parks of 2021 include Glacier Bay and Great Basin

Want to experience the great outdoors without the crowds this summer? Consider these lesser-known, undeveloped national parks that had the fewest visitors in 2021.

There are 63 national parks in the US and a total of 423 national parks. But despite the wide range, 25% of all recreational visits were to the eight most visited parks, which accounts for only 2% of all parks in the national park system.

“We’re pleased that so many visitors are returning to famous parks like Yellowstone and Yosemite, but there are hundreds more that should be on everyone’s bucket list,” National Park Service Director Chuck Sams said in a February press release.
