How to Book Recreation.gov: Cancellations, Release Times and Alerts
How Recreation.gov works
Recreation.gov is the single federal booking system — nearly every wilderness permit, river launch, lottery and federal campground in the country runs through it, sold by the Park Service, Forest Service, BLM, Army Corps and Bureau of Reclamation on one shared site. This page is PermitSnag's guide to booking on it; the reservation itself happens on recreation.gov.
When cancellations show up
Recreation.gov opens booking windows on its own schedule, and it varies permit to permit and campground to campground — the individual listing on recreation.gov is the source for that date. What's constant is what happens once a window is full: cancellations happen, and they go straight back onto the calendar the moment someone gives up their spot. PermitSnag watches the permits and campgrounds you tell it to and texts or emails you the moment a cancellation opens one back up.
How a PermitSnag watch helps
A PermitSnag watch checks Recreation.gov on your behalf and texts or emails you the moment a cancellation lands, so you are not the one refreshing the page. Set a watch on any permit or campground you can reach from the links below, or search for it from the full permit directory.
