Sold out doesn’t mean full.
A booking page can only sell you a reservable site. It can’t sell you a walk-up spot, or free public land just down the road, or the reservation somebody’s about to cancel. Outdoors finds all three.
- Drive up and take one — first-come sites can’t be reserved online, so a booking page has no way to show them as anything but unavailable. We mark them as fair game.
- 13,633 free spots, no booking — dispersed camping on public land, ranked in the same list as the paid sites. No reservation, no fee, never sold out.
- Stop refreshing the page — we re-check your exact dates every 9 minutes and email you once, when something actually opens.
Free to search. Every campground page shows you which nights are open, night by night.
