Black Bear Pass

The trail typically starts from U.S. Highway 550 at the summit of Red Mountain Pass (elevation 11,018 feet), located between Ouray and Silverton, Colorado. Look for signs for Black Bear Road or Forest Road 823/648, often near mile marker 80 on US-550. The initial section is two-way, climbing towards Black Bear Pass. A significant portion of the trail, particularly the steep descent towards Telluride including the switchbacks above Bridal Veil Falls, is strictly one-way downhill. The trail ends near the town of Telluride. Unlicensed vehicles may need to arrange for a pickup at the bottom of the one-way section before reaching Telluride.

This is an expert-level trail, considered one of the most dangerous in Colorado. The primary challenge is the one-way downhill section which is extremely narrow, steep, and has severe exposure with drop-offs that can exceed 1,000 feet. A critical obstacle is 'The Steps,' a series of off-camber rock ledges requiring precise tire placement and often a spotter. Drivers will encounter extremely tight switchbacks, loose rocky surfaces (including shale), and sections where the road is barely wider than a vehicle. High-clearance, short-wheelbase 4x4 vehicles with low-range gearing, robust tires, excellent brakes, and good suspension articulation are mandatory. Lockers are highly recommended. This trail has a very high 'pucker factor' and is absolutely not for stock vehicles or drivers lacking extensive experience on highly technical and exposed off-road terrain. Body damage is a distinct possibility.
