All 63 national parks, most crowded first
Each bar shows 2025 recreation visits divided by gross acres. The bars use a log scale: the most crowded park gets about 6.5 million times more visits per acre than the least crowded, so a linear scale would hide every park but Gateway Arch. Each bar is labeled with its value.

A recreation visit is one entry, not one unique person. Acres are gross acres inside the park boundary, from the NPS Listing of Acreage. Where np.guide has a field guide for the park, the park name is a link to it. Select a column name to sort the table.

Methodology
- Visits: NPS Visitor Use Statistics (IRMA), annual recreation visits for each park in 2025, the latest full calendar year, exported October 2026. Sequoia (SEQU) and Kings Canyon (KICA) are separate units.
- Acres: gross area acres from the NPS Land Resources Division Listing of Acreage, 31 December 2025. Gross acres are federal plus non-federal land inside the park boundary.
- Seven parks have one IRMA visit count for a park plus an adjacent preserve: Denali, Gates of the Arctic, Glacier Bay, Great Sand Dunes, Katmai, Lake Clark, and Wrangell-St. Elias. Their acres are the sum of both units. New River Gorge is already one unit in both sources.
- Visits per acre is visits divided by acres. The table rounds acres to whole numbers; the division uses full acres.
- Visits spread unevenly inside a park. Gateway Arch visits concentrate around the Arch grounds. The Alaska parks include large areas with no road access. A low number does not mean every part of the park is empty.
