State parks that require day-use reservations

More parks now cap daily visitors and turn away people without a reservation or timed-entry pass. These 27 parks in 11 states say on their official pages that a day-use reservation, pass or permit is required, either all the time or on weekends, holidays or in peak season. Each park page shows exactly what the park says. Parks that only recommend reservations are not listed.

Detected automatically from official wording and re-checked with each park page. If a park is missing or wrong, tell us.
