Timed-Entry Reservations at National Parks: How the System Works

More national parks run timed-entry reservation systems every peak season, aimed at easing congestion at trailheads and parking areas that were never built for current visitation. The list of parks changes year to year; the booking mechanics do not.

How the window works

Reservations are released on a rolling window through Recreation.gov, with a portion of each day's slots held back for next-day booking. If you've navigated a timed-entry system at one park before, the process at any other will feel familiar — same platform, same queue behavior.

Plan ahead

Set a calendar reminder for the release date, have your Recreation.gov account and payment method ready beforehand, and log in a few minutes early rather than exactly on time. Popular summer weekends can sell out within minutes of release, and the next-day-booking pool moves even faster.

If you miss the window

Check back the morning of your planned visit — cancellations and the next-day allotment both restock the calendar, and a surprising number of trips get booked from no-shows alone.
