The Ultimate GPS Map App for Your Outdoor Pursuits
onX Backcountry lets you easily find and navigate trails—whether you’re seeking new backcountry ski lines, climbing routes, or trails to hike and mountain bike. Plan with the best maps and trustworthy trail info, and navigate confidently with offline maps and GPS tracking.

Discover New Adventures
Whether navigating a ski tour, hike, run, mountain bike, or backpacking trip, we’ve got you covered. With over 650k miles of trails, including hiking trails, mountain bike trails, backpacking trails, and ski routes, our maps will help you discover adventures nearby.

Prep Better With Powerful Map Tools
We adventure in three dimensions, and your maps should reflect that. With a 3D map, you can visualize terrain, scout ski lines, and plan for hazards before you hit the trail. See recent conditions with weather forecasts, reports from other trail users, and get snow info from SNOTEL stations and regional avalanche forecasts. Map out custom routes with snap-to-trail functionality, and use Waypoints, Slope Angle, Slope Aspect, Trail Slope, and Wildfire Layers for detailed planning.

Navigate Without Cell Coverage
Save Offline Maps to bring your custom maps when you're outside cell coverage. With the onX Backcountry App, turn your phone into a handheld GPS device using your phone's internal GPS. Navigate offline by following the blue dot to always know how to get home. Leave a breadcrumb trail with Tracker to see where you’ve been and measure your key trip stats.

The Best Maps
With map data sourced from USFS, BLM, and NPS, our color-coded base maps help you easily find what you’re looking for. Scout the landscape and visualize terrain by viewing your maps in 3D, topo, satellite imagery, or a hybrid.
