Better Maps, Better Decisions
onX Backcountry is built for the way the backcountry actually works—where success isn’t a single moment, it’s the sum of a hundred good decisions. Find new terrain, understand what you’re getting into, plan your route with the most detailed maps available, and trust them to be there when you’re deep in and your signal isn’t.
See It Before You Go
Study terrain in 3D, check slope angles, mark potential campsites or water crossings, and plan your route with the highest-resolution topo maps available. Know exactly what’s ahead—before you ever leave home.
Know What’s Next, Mile by Mile
From weather forecasts to trail slope, onX puts the right information at the right moment—so you can focus on the experience, not the uncertainty.
3D Terrain & Peak Labels — Offline
Visualize your route in 3D before you step foot on the trail—and bring that view with you, offline, so you’re never guessing at what’s around the bend.
LiDAR Topo Maps
Visualize your route in 3D before you step foot on the trail—and bring that view with you, offline, so you’re never guessing at what’s around the bend.
Slope Angle Shading
Color-coded slope angles show you whether you’re heading for a stroll or a scramble and let you see the steepness of the terrain.
Weather & Conditions
Real-time weather gives you the environmental awareness to know when to push on and when to turn back.
Custom Waypoints
Mark campsites, water crossings, bail-out points, mushroom patches, or bigfoot sightings with custom icons, colors, and your own images to make sense of your map.
Land Ownership & Access
Understand exactly where you can go, camp, or cross with comprehensive public/private land boundary data—built on the same industry-leading ownership database behind onX Hunt.

Follow your route with reliable Offline Maps and up-to-date conditions like wildfire and smoke info so you can change your plans in response to a changing landscape.
Step 3: Get Back
Track your route to see how far you’ve gone and leave a digital breadcrumb trail to find your way back.

Great app for backcountry adventures with no service. Being able to download detailed 3D maps offline is great. I use this app multiple times a week for ski touring, mountain biking, and hiking.

I’ve tried virtually every single GPS app and this is hands down the best one! Planning, navigating, and researching an adventure must be precise! That’s exactly what OnX brings to the table!
