The National Park Service keeps recreation visit statistics for more than 400 parks in the National Park System. The National Mall and Memorial Parks in Washington are often cited as the most-visited park in the system with an estimated 32 million visitors each year, but that park doesn’t show up on its own in the data. Instead, the park service keeps visitor statistics for attractions you can find there, such as the Washington Monument and Lincoln Memorial.

Here’s a list of the top 10 most visited National Park Service sites in 2020, according to the park service:

  1. Blue Ridge Parkway, Virginia and North Carolina, 14.1 million.
