onX Offroad: Trail Maps & GPS

Review by eFreeware

The hardest part of planning a day off-road is rarely the driving. It's knowing which trails are actually open to your machine, where the boundary between public land and private property sits, and whether the spot you picked for the night is somewhere you're allowed to camp. Paper maps go stale, and general navigation apps tend to treat a graded forest road and a rock crawl as the same thin gray line.

onX Offroad, from the mapping company onXmaps, is built for that gap. It's a trail and land-boundary app for motorized recreation: 650,000-plus trails and 500,000 recreation points layered over 852 million acres of public land in the US. It has been available since April 2019, and with more than a million installs and a 4.9 average from over 10,000 ratings, it clearly lands with the crowd it targets.

Trails sorted by what you actually ride

What I like about the structure here is that the trail catalog is filtered by vehicle type rather than shown as one undifferentiated mass. You can narrow the map to 4x4 routes, side-by-sides, ATVs and quads, dirt bikes, dual-sport and overlanding rigs, or snowmobiles. Each trail carries a difficulty rating and open and close dates, so a route that suits a lifted truck doesn't get mixed in with one that only makes sense on a snowmobile.

The map layers do a lot of the heavy lifting. You can toggle weather, land boundaries and cell service, and the coverage layer is broken out for AT&T, Verizon and T-Mobile, which is the kind of detail that matters once you're past the last gas station. Wildfire and drifting smoke information comes in from the NIFC and NOAA, so an area that looks clear on a trail map can be checked against what's actually burning.

The imagery options are broad — 3D, topographic, satellite or hybrid — and the developer says the 3D 24K topographic maps cover the entire US at the membership level. I'd expect most riders to settle on one or two views and ignore the rest, but having satellite alongside topo is useful when you're trying to judge whether a shelf road has any width to it.

Navigation that starts on pavement

Getting to the trailhead is part of the trip, and this is where a lot of trail apps fall down. onX Offroad handles turn-by-turn directions with voice guidance from the tarmac to the trail, and it syncs with Android Auto, so the same routing can run on a vehicle screen rather than a phone propped on a dash. Routes you build snap automatically to roads and trails, which saves the fiddly work of placing points by hand.

The trip tracker records distance, location, speed and elevation, and trips can be saved and shared. Waypoints let you mark campsites, fuel stops, fishing access, rock crawls and anything else worth remembering. Campgrounds, trailer parking, trailheads and non-ethanol fuel are among the places the app can locate.

Location Sharing is the newest addition, and it's session-based: your group appears on the map in real time while the session is running. For a group ride spread over several miles of forest, that's a meaningful safety net — knowing where the last rider is without radio check-ins every few minutes. The developer describes it as seeing your whole crew move in real time, and that's the pitch.

Camping and land access without the guesswork

Dispersed camping is the feature I'd point a new user to first. Using USFS verified data, the app marks spots where you can camp for free and legally on BLM land and in National Forests, and places them beside motorized trails. Anyone who has spent an evening squinting at a county line on a downloaded PDF will recognize the value of having that information on the same screen as the route.

Property lines are the other half of that picture. Public and private land ownership information is available nationwide, with National Forest, BLM and National Park land identified, so you can see where you're allowed to be before you commit. Property lines require a membership.

Between the two, the app answers the question that causes the most trouble in the field: not where can I drive, but where am I permitted to stop, camp and stay. That's a narrower promise than it might sound, and it's the one the app is genuinely built around.

What you need before you head out

The download is free, and in-app purchases are offered. A membership unlocks the full 650,000-plus miles of motorized roads and trails, offline maps, 3D 24K topographic coverage for the whole country, and nationwide property lines. If you're weighing the app, that split is the main thing to understand going in.

Offline maps are worth calling out because they're the feature that decides whether the app works where you're going. Saved maps keep the interactive land and trail data intact, so the layers you rely on don't go blank once the signal does. Cell coverage layers help you plan around that, but the saved map is what carries you through.

There's also onX SOS, sold as an add-on subscription at $49.99 per year and available at every account tier. It's billed as putting a professional rescue crew on call around the clock, coordinating the response and covering the cost of rescue and evacuation, with no extra hardware, no two-way comms, no deductibles and no claims process. It's powered by Overwatch x Rescue. It is a distinct purchase from any membership.

Riders who get the most from it

This is an app for people whose recreation depends on knowing land status. Four-wheelers, side-by-side owners, ATV and quad riders, dirt bikers, dual-sport and overlanding travelers, snowmobilers — anyone whose route planning starts with the question of what's legal and open. If your weekends involve a trailer, a group and a route you haven't ridden before, the combination of trail filters, boundaries and camping data is exactly the toolkit you'd want.

It also suits the planning side of a trip as much as the driving side. Marking waypoints, saving a route, checking cell coverage before you commit and sharing a live session with the group are all things that happen before and during a ride rather than after it. Snowmobilers get their own slice of trail information, which is a reminder that the app is organized around motorized access rather than general outdoors use.

The membership structure means the free download sits alongside a paid tier. Riders who only need occasional trail ideas may find the free side sufficient; those who want offline maps, full property lines and 3D topo across the country are the ones the membership is built for.

The case for putting it on your phone

onX Offroad does a specific job well: it puts trail access, land ownership and camping legality on one map, then gets you to the trailhead with turn-by-turn directions. The layer set — cell coverage by carrier, wildfire and smoke data, property boundaries — is the kind of thing that only matters off pavement, which is precisely why a general navigation app won't substitute for it.

The caveats are straightforward and worth weighing honestly. A good portion of the headline capability sits behind a membership, SOS costs extra on top of that, and the app's focus is motorized off-road travel rather than hiking or general exploration. Nothing here is hidden.

If you ride trails regularly and want to stop guessing about boundaries, closures and where you can camp, this is a well-established option with a strong user rating behind it. Install the free version, see how the trail filters and land layers line up with the places you ride, and decide from there whether the membership deserves a spot in your trip planning.
