Nearby springs
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.
Hot Sulphur Springs Resort & Spa
A long-running hillside resort in the town of Hot Sulphur Springs with about 19 public mineral pools between 98 and 112°F. Day passes are walk-in only, and some pools are restricted to ages 12 and up. The property also has a motel, private baths, massage and a grill.
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.
