As you walk the 1/4 mile trail to the hot springs, you are enveloped in the dark hues of primeval woodland, touched by mottled light filtering down from treetops high above and the invigorating scene of the lagoon with the gorgeous Rider Creek waterfall spilling into it.
There are six soaking pools spaced apart by rock walls laid out in steps down a ravine. The water comes out of a spectacular rock formation.
This site has been improved throughout the years by the Forest Service, many volunteers, and the users of the area. Clothing is optional at the hot springs.
