Glade Road to Turkeyfoot Ridge — Daniel Boone National Forest Red River Gorge Backdoor via Tunnel Ridge Road

Tunnel Ridge Road (FR 39) is the spine of this run — a gravel and hardpan Forest Service route that ribbons along the high sandstone benches above the Red River Gorge Geological Area in the Daniel Boone National Forest. Starting near Nada Tunnel, you work northeast through mature second-growth hardwood and hemlock, passing pull-offs above Clifty Wilderness and eventually reaching Turkeyfoot backpacker camp — a legitimate overlanding rest stop with views deep into the gorge system. The narrow road forces you to be precise; overhanging rock faces and blind curves are the obstacle here, not mud or rock crawling.

This is a high-clearance route, not a 4WD technical challenge — a stock Tacoma or Wrangler on all-terrains handles it fine in dry conditions. Spring and late fall are the sweet spots for color and moderate temps; summer brings humidity and congested trailheads. No permit required for vehicle travel, but the adjacent Clifty Wilderness is foot-traffic only. Tunnel Ridge Road is sometimes closed by the Forest Service after heavy rain or winter ice — check the Cumberland Ranger District road conditions before you leave pavement. Cell service is essentially gone once you drop below the ridge. Dispersed camping is permitted along the road corridor outside designated wilderness boundaries.
