Dunton Hot Spring emerges at 108 degrees Fahrenheit in the remote San Juan Mountains at 8,850 feet, requiring a short walk through alpine terrain to reach a thermal feature surrounded by peaks exceeding 13,000 feet elevation.

Average winter snowfall exceeds 134 inches annually at this remote location.

History of Dunton Hot Spring

Dunton Hot Spring lies near the historic log buildings of Dunton, an early settlement in Colorado's San Juan region. The spring's 108-degree water and moderate mineral content suggest circulation to depths of 2,000-3,000 feet through the San Juan volcanic system, reflecting regional tectonic and geothermal patterns.

Locate the spring via trailhead near Dunton's restored historic buildings, approximately 25-35 miles southwest of Telluride. A short walk of 300 meters reaches the thermal area. Summer provides the only practical access window; winter and spring snowmelt close the approach road. Plan for cold nights even in peak season.
