Vulcan Hot Springs sits near Cascade, Idaho, alongside a mountain waterway. The iron-rich water emerges at around 40°C, feeding indoor and outdoor pools with a sauna and massage services on site.
Insider tip — Cascade in Valley County, Idaho is a mountain town on Cascade Reservoir in the Payette River Valley — gateway to the West Mountains and the Frank Church Wilderness. Vulcan Hot Springs in the Boise National Forest south of Cascade provides iron-rich thermal bathing in a volcanic landscape of the Salmon River drainage, accessible to hikers willing to venture into the Idaho mountain wilderness where geothermal activity has been creating hot springs in the volcanic highlands since the Cascades volcanic arc was first active.
