What happens to national parks during a shutdown
When federal appropriations lapse, the National Park Service furloughs most of its staff. There is no single rule for what happens to the parks: some close entirely and barricade their entrances and roads; many stay physically accessible but completely unstaffed — no visitor centers, no rangers, no road plowing or maintenance, restrooms locked, trash left to pile up; a handful keep running because a state or a gateway community steps in to fund operations. New permits, reservations, and special-use approvals stop being processed.
This page checks the NPS operating-status page every hour, so if a lapse begins it will say so here first.
