Forest Road 445 – Big Burro Mountains Loop
Technical mining district in remote desert mountains
Forest Road 445 winds through the heart of the Big Burro Mountains, connecting a network of abandoned copper and silver mines that fueled southwestern New Mexico’s boom-and-bust cycles. The route passes the remnants of Tyrone, once a major copper camp, before climbing into technical terrain where mine tailings and loose rock challenge traction and undercarriage clearance. Signal Peak, at 8,032 feet, offers commanding views across the Chihuahuan Desert toward Mexico’s Sierra Madre.
This is serious 4WD country requiring skid plates and recovery gear. The rocky climbs and off-camber sections demand experience, especially the descent toward Leopold. Summer heat makes this route brutal – stick to cooler months when possible. No services exist along the route, and cell coverage is nonexistent. Water is scarce, so pack plenty. The payoff is solitude in some of New Mexico’s most remote backcountry, where you might not see another vehicle for days.

Frequently asked questions
What vehicle modifications are required for FR 445?
You need a modified 4WD with skid plates minimum - stock vehicles will get destroyed on the sharp volcanic rock. Rock sliders and underbody armor are essential, plus good tires that can handle jagged terrain.
Is the trail accessible in summer?
No, avoid May through September due to extreme desert heat and afternoon thunderstorms that create flash flood conditions. October through April is the safe window.
Do I need permits to run the Big Burro Mountains Loop?
No permits required - it's all Gila National Forest land. Just follow Leave No Trace principles and pack out all trash.
What's the gnarliest section I should expect?
The mining district climbs get extremely technical with loose rock shelves and off-camber ledges around 7,000+ feet elevation. Multiple body damage spots if you're not careful with your lines.
How much fuel range do I need for this loop?
Plan for at least 300 miles total range from Silver City - no gas available on trail and you're 60+ miles from the nearest station once committed to the loop.
