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.
