Rainbow Hot Springs
Rainbow Hot Springs beckons adventurous soakers willing to undertake a substantial backcountry journey in the San Juan Mountains near Pagosa Springs, where this remote 104°F thermal source emerges at 9,037 feet elevation within San Juan National Forest.
The spring requires approximately 3.6 miles of hiking through high-elevation terrain. The landscape transitions from forested lower elevations through subalpine conditions to the remote location. Spruce and fir forests surround the spring in terrain characterized by significant precipitation and an average of 144 inches of annual snowfall, creating a challenging but rewarding wilderness setting.
The spring sits within the Weminuche Wilderness boundary, representing a protected geothermal resource in one of Colorado's largest wilderness areas. The Rainbow Trail provides the primary access route from West Fork Campground. Historical use remains undocumented, but the remote location has limited human impact through most of recorded time.
This spring requires full backcountry preparation including reliable maps and wilderness experience. Summer months from July through September offer the only practical visiting season due to deep snow and difficult access conditions throughout the rest of the year. West Fork Campground sits 5.1 miles away as the nearest developed facility for trip preparation and resupply.
