An independent OHV / MVUM data project
Where can you legally ride?
Pick a state and a vehicle — ATV, dirt bike, side-by-side, 4x4 or e-bike — to find the national-forest ranger districts with designated routes on the Forest Service Motor Vehicle Use Map. Then open a district for miles, seasons, a route map, and GPX.
How it works
- Pick a state and vehicle. The finder lists the ranger districts whose MVUM designates that vehicle class — or use "Trails near me" to sort by distance to you.
- Open a district. Every district page carries total miles (roads + trails), a per-vehicle access matrix with seasons, and a route-network map — no two pages share a number.
- Download the GPX. Grab all routes, or just the ATV-legal ones, for your GPS or riding app — then carry the official MVUM when you ride.

What this site is
OHV Trail Finder is a free, no-signup finder for legal off-road riding on U.S. national-forest land. Pick a state and a vehicle type — ATV, dirt bike, side-by-side, 4x4 or e-bike — to find the ranger districts with designated motorized routes on the U.S. Forest Service Motor Vehicle Use Map (MVUM), then open any district for its total miles, a per-vehicle access matrix with seasons, a route-network map, and GPX downloads for your GPS or riding app. It covers 448 ranger districts across 40 states and 106 national forests — 231,615.7 miles of routes in all. Every figure comes from the MVUM data and is informational, not a legal document.
OHV Trail Finder is an independent data project. Every mile, vehicle designation and season comes from the U.S. Forest Service's Motor Vehicle Use Map data — public domain — and the method behind each figure is documented. It exists because this information otherwise lives only in clunky per-forest PDFs. Read more on the methodology page.
