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 five soaking pools spaced apart by rock walls laid out in steps down a ravine. The pool floors are mostly bedrock but some gravel, sand and debris remain at the bottom of the pool.
Clothing is optional at the hot springs.
