Forest Road 222 – Crooked River Trail

Forest Road 222 follows the old Crooked River mining district route, a barely-two-vehicle-wide shelf road carved into steep canyon walls above the Middle Fork Boise River. Built in the 1890s to service gold and silver claims, this gnarly 15-mile track features multiple hairpin turns with thousand-foot drop-offs and several sections where the road has partially collapsed into the canyon. The route passes abandoned mine shafts, rusted equipment, and the ghost town remnants of Rocky Bar, where weathered cabin foundations and mining debris tell stories of boom-and-bust cycles.

This is expert-level territory requiring experienced drivers, full skid plates, and recovery gear. The narrow shelf sections have zero room for error, and oncoming traffic means backing up for miles to find a passing spot. June through September only, after snowmelt but before hunting season crowds. No permits needed, but inform someone of your plans—cell service is nonexistent and help is hours away. The technical challenge and mining history make this a bucket-list run for serious 4WD enthusiasts, with primitive camping available at old mining sites.
