What it does
What onX Backcountry Trail Maps GPS does
onX Backcountry Trail Maps GPS provides maps and navigation tools for hiking, mountain biking, climbing and backcountry skiing. It shows topographic terrain, trails and land boundaries, and can help you plan routes before heading into areas with limited or no mobile service. The app is aimed at people who spend time outdoors and need more detail than a standard road map.
Maps and route planning
You can view terrain in 2D or 3D, switch between activity-specific map modes, and build routes that follow established trails. Ski users can check slope-related terrain information, while hikers, riders and climbers can focus on trails, approaches and other activity-relevant details. Map layers also identify public and private land, including ownership information where available.
Use away from mobile coverage
Selected maps can be saved for offline use, so the core map view remains available when your phone cannot connect to a cellular network. This is useful for remote trips, but the app still depends on your phone's GPS and battery. It is a navigation aid rather than a replacement for route preparation, local conditions checks or basic outdoor safety planning.
Hazard information and app details
Additional layers cover information such as wildfire and smoke conditions, snow and avalanche terrain exposure, and nearby trail or climbing data. The amount of detail can be useful when comparing routes, though it also means the app is more suited to users who want map controls and planning information rather than a simple point-to-point guide.
