Sulphur Spring
Sulphur Spring emerges at a modest 68°F in a northern California interior valley, sitting just 5.9 degrees above ambient temperature within a state conservation area.
The spring flows at 1,454 feet elevation through oak and grassland habitat along Walker Ridge Road, accessible via a short walk through regional water district land designated for conservation and wildlife protection.
Located in Lake County near Clearlake Oaks, this thermal feature lies on permanently protected land managed by California Department of Fish and Wildlife, with water chemistry typical of regional volcanic activity.
The Indian Valley Wildlife Area provides public access year-round on a first-come basis. Nearest camping is at Little Stony Campground, 22.5 kilometers away. Best visited during mild months; cool water ideal for quick dips.
