▶Discover New Adventures

Whether navigating trails, ski and snowboard routes, or backpacking trips, we’ve got you covered with over 650k miles of hiking, skiing and biking trails.

▶Prep Better With Powerful Maps Tools

We adventure in three dimensions. With a 3D map, you can visualize mountain bike trails, scout skiing lines, and plan for hazards before you hit the hiking or ski trail. See recent conditions with weather forecasts, reports from other trail users, and get snow info from SNOTEL stations and regional avalanche forecasts to plan your snow skiing or snowboarding adventure. Map out custom hiking, mountain bike and skiing trails with snap-to-trail functionality, and use Waypoints, Slope Angle, Slope Aspect, Trail Slope, and Wildfire Layers for detailed route planning.

▶Hike, Ski, Bike & Navigate Without Cell Coverage

Save Offline Trail 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 hiking, skiing, and snowboarding trails 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.
