Nearby springs
Radium Warm Springs
A warm spring pool above the Upper Colorado River near the hamlet of Radium, southwest of Kremmling. The BLM directs visitors to a trailhead at the end of Warm Springs Road, because the old social trail from the CPW Mugrage site is closed to protect bighorn sheep habitat. A fee campground and river access are nearby at the Radium Recreation Area.
Indian Hot Springs
A historic spa in Idaho Springs with separate men's and women's geothermal cave baths, a mineral-water swimming pool and private tubs. Lodging, a restaurant and spa services are on site. Prices and cave rules should be confirmed directly, as public listings conflict.
Eldorado Springs Pool
A historic outdoor swimming pool at the mouth of Eldorado Canyon near Boulder, fed by the area's artesian warm springs and reopened after a long renovation. It operates in summer and on September weekends. This is a warm swimming pool rather than a hot soak.
