Booking windows for U.S. state park campgrounds vary widely, ranging from as little as 90 days to as far out as 14 months, depending on the state and whether you are a resident. Most states open reservations at a specific time of day, often between 7:00 AM and 10:00 AM local time, and popular parks can sell out within minutes. As a general rule, if a state allows bookings 6 months in advance, a campsite for July 15, 2026 would become available on January 15, 2026, typically at the state’s official release time. For states with 365-day or 12-month windows, that same campsite would open on July 15, 2025, while states with shorter windows like 90 days wouldn’t allow booking until April 16, 2026. Knowing these windows—and being ready at release time—is the key to securing high-demand campsites.
