Best U.S. National Parks You Must Visit

Year after year, visitors flock to America's National Parks to bask in the country's incredible natural beauty. In 2020, the National Park Service recorded over 237 million visits across sites like the Blue Ridge Parkway — the most popular with over 14 million visits last year — and National Parks. From sea to shining sea, the U.S. contains a stunning array of diverse landscapes, from dramatic canyons and vast deserts to snowy mountain peaks and verdant valleys. When it comes to choosing the best national parks in the U.S., we think the visitor numbers speak for themselves.

While all 63 National Parks are worth visiting, the top 15 most-visited ones are truly some of the nation's best, with bucket-list destinations like the Grand Canyon and Yosemite making the cut. Of course, if you want to avoid the crowds, you can always check out the least-visited national parks.
