Columbine Lake Trail Out and Back

About

The Columbine Lake Trail Out and Back is a strenuous mountain biking route in the San Juan National Forest near Silverton and Telluride. The trail climbs to an elevation of approximately 12,700 feet, with the lake sitting at roughly 12,500 feet. The total distance is cited as 6.7 miles in some sources, while others describe a longer 17.8-mile variant starting from Rainbow Trail. The ascent is steep, with the first two miles often requiring hike-a-bike due to steep switchbacks. The trail flattens out near the lake basin. The descent is characterized as fast and technical with sharp switchbacks. Parking is available at the Ophir Pass Road trailhead or via FS Rd 820, which requires 4x4 access. The trail is accessible from April through October, depending on snow conditions. Riders should expect alpine conditions including wind, cold, and potential lightning. The trail is shared with hikers, who are the predominant users, so riders must yield to uphill traffic. Pets are permitted.
