Outdoors is better in the app.

Free on iPhone and Android. Take your maps with you, even where your phone has no bars.

  • Maps that work with no signal — Save a trail or a whole area before you go.
  • Know the trail before you go — Distance, climb, photos and weather.
  • Find your campsite — Real campgrounds, down to the site.
  • Build your own maps — Pin camps, draw routes, share or keep private.

Live campsite finder · all 50 states

Every kind of campsite. One search.

Reservable sites, first-come spots and free camping on public land, all on one map for your dates. No more jumping between booking sites to find somewhere to sleep.

  • Open sites for your dates — live availability at reservable campgrounds, never more than 10 minutes old.
  • 21,456 free spots on public land — dispersed camping with no reservation and no fee, in the same list as the paid sites.
  • Walk-up sites count — first-come sites can’t be booked online, so booking pages never show them. We do.
  • Full for your dates? — we check again every 9 minutes and email you once, when something opens.

Free to search. Every campground page shows you which nights are open, night by night.
