Access

A historic natural hot springs on the west bank of the Crystal River, opposite Pitkin County’s Filoha Meadows Nature Preserve, with Redstone as the nearest town. The county bought the 0.1-acre parcel in 1991 and adopted it into the Open Space and Trails program in 1999; the county lists the site as open year-round with access from Highway 133. A management plan adopted in March 2020 led the county to secure a lease over part of the Colorado Department of Transportation right of way that takes in some of the pools, the parking area, and the slope between the highway and the river, so the county can manage that ground and restore degraded areas.
