The network's seasonal shape.
Each row below sums Recreation Visits across every NPS unit that reports data, for that calendar month, averaged over the 2021-2025 window. The bar widths are proportional to the busiest month.
National Parks specifically (the 63 units with the official "National Park" designation) follow the same shape but with sharper summer compression; the marquee parks are mostly seasonal:
| Month | Network total | Parks only | Parks share |
|---|---|---|---|
| January | 13,668,655 | 2,883,609 | 21% |
| February | 14,781,248 | 3,169,267 | 21% |
| March | 23,452,151 | 5,252,820 | 22% |
| April | 27,397,432 | 6,072,609 | 22% |
| May | 32,571,152 | 8,530,633 | 26% |
| June | 40,054,110 | 11,381,605 | 28% |
| July | 43,972,799 | 13,079,883 | 30% |
| August | 38,674,379 | 11,449,013 | 30% |
| September | 32,551,044 | 9,849,202 | 30% |
| October | 29,377,126 | 8,190,450 | 28% |
| November | 20,043,758 | 4,638,124 | 23% |
| December | 17,091,735 | 3,774,827 | 22% |
How to read the curve
The peak-to-quietest ratio at the network level (~3×) understates how seasonal individual parks actually are. Yellowstone's ratio is closer to 40×; Glacier's is higher still. The network curve flattens because warm-weather units fill in the winter months. If you want national park visitors by month for a single park rather than the whole system, each park's best-time-to-visit page carries its own monthly curve; Yellowstone, Yosemite, and Grand Canyon are linked below.

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. Monthly aggregation uses the 5-year mean from the per-unit monthly visitation dataset. Some units don't yet have a complete five-year window of monthly data; those units' contributions are smaller until the next annual refresh.
Common questions.
What month do national parks get the most visitors?
July is the busiest month across the National Park Service network, with a five-year mean near 43.97M recreation visits, about 3 times the quietest month.
What is the least busy month for national parks?
January is the quietest month network-wide, with a five-year mean near 13.67M recreation visits. Winter traffic concentrates in the warm-weather desert and subtropical units.
What share of national park visits happen in summer?
About 47% of the network's yearly recreation visits land in June through September. That summer compression is even sharper at the marquee mountain parks, whose interior roads are only open part of the year.
