National Parks in Wyoming.

By Nicholas Major · Last updated

Wyoming has Yellowstone and Grand Teton (two of the country's most-visited National Parks) plus Devils Tower, Fossil Butte, and a corridor of National Historic Sites. Jackson Hole (JAC) is the dominant anchor for the southern Teton entrance; Bozeman (BZN, Montana) and Cody (COD) are the main alternatives for Yellowstone's north and east entrances. Yellowstone's interior is closed to wheeled vehicles from early November through April; the year-round corridor from Gardiner through Mammoth to the Lamar Valley and out the Northeast Entrance is the winter alternative, with snowcoach and snowmobile access reaching the geyser basins. Grand Teton has Jackson Hole air and road access year-round but most interior services run late May through September. The state's NPS network is summer-dominant: roughly half its annual visits arrive between late June and early September.

Methodology

Rows come from our combined NPS metadata and Visitor Use Statistics registry, not the Park Service's official census of 433 managed system units. Per-record 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 records are listed under every state they touch, and their full visit total appears in each state. Official National Park counts use the central 63-park classification rather than the source designation label alone. Independent site, not affiliated with the National Park Service.
