Ranked by five-year average.
These twenty-five parks carry the bulk of the National Park system's foot traffic. Recreation Visits is the official NPS visitor count and excludes other categories (Recreation Visit Hours, Tent Campers, Backcountry Campers) that some units also report. Sorting by the 2021-2025 average rather than a single year reduces the influence of one-off events — the 2020 pandemic closures, the 2022 Glacier road washouts, the 2025 Dragon Bravo fire at Grand Canyon's North Rim. The ordering you see is the network's structural ranking.

What this ranking does and doesn't tell you
An annual total is the right number for "which park is most popular" — but it can be misleading for trip planning. Two parks can have the same annual total but radically different crowd intensity. Grand Canyon and Rocky Mountain National Park land within a few hundred thousand visits of each other most years, but Rocky Mountain's traffic is compressed into a much shorter summer window (because Trail Ridge Road is open less than half the year), so its peak-month intensity is far higher than its annual rank suggests.
For peak-month intensity, see the busiest-by-peak ranking. For the inverse — parks that stay quiet even at peak — see least crowded. For the network's seasonal shape, see visitation by month.
Methodology
Visit counts are official "Recreation Visits" from the NPS Visitor Use Statistics Data Package, 2025. The five-year average column averages 2021-2025 to reduce single-year noise; the latest-year column shows the most recent complete calendar year. Some NPS units publish other statistic types (Tent Campers, Recreation Visit Hours) that are not used here. Independent site, not affiliated with the National Park Service. National Parks ranked here are only official units with the 'National Park' designation; National Monuments, National Recreation Areas, National Seashores, and other NPS unit types are not included in this list. The full network of 400+ NPS units is covered separately.
