PermitSnag answers permit and campground questions for US backcountry trips. Ask how to get a permit and you get how it is issued (lottery, reservation or in person), the season, the dates the agency has published, any closures, and the official booking page. Ask about specific dates and you get what our checks last recorded, with the time we looked. A date we have not checked comes back as unknown. It is never reported as sold out. It covers wilderness, backpacking, climbing and river permits in national parks, national forests and state parks, and campgrounds booked on Recreation.gov and on state park systems. Three limits. It does not book, pay or enter a lottery. It does not show live inventory, because it reads our stored checks and does not call a booking site when you ask. And this listing cannot set up alerts. PermitSnag can send an alert when a spot opens on some permits and campgrounds, and you set that up on permitsnag.com. No account or sign-in is needed.
