Methodology
Unit list and per-unit visit counts come from the official NPS Visitor Use Statistics Data Package, 2025. The "5-year average visits" column is the mean of 2021-2025 Recreation Visits. Multi-state NPS units (Yellowstone, Death Valley, Great Smoky Mountains and others) are listed under every state they touch; the per-unit visit count is the unit's total, not a per-state share.
