Recreation visits are entries, not unique people. The average columns rank months by mean visits in 2015 to 2024, without 2020 and 2021. A dash in the peak divided by quiet column means the quietest month had zero reported visits, so the ratio has no value. Select a column name to sort the table.

Methodology
- Source: NPS Visitor Use Statistics (IRMA), "Recreation Visitors By Month (1979 – Last Calendar Year)", exported October 2026 with a cache-busting fetch. One report per park (
Park=four-letter code). - Analysis year 2025 = latest calendar year with all twelve months present for every park in this dataset. 2026 monthly totals in IRMA are still partial.
- Busiest month = highest recreation visits in 2025; quietest = lowest (including months with zero reported visits).
- The average columns rank months by mean visits in 2015–2024, excluding 2020 and 2021 (COVID disruption), same era window as the visitation trends page.
- Sequoia (SEQU) and Kings Canyon (KICA) are separate IRMA units.
