Seyferth Hot Springs
Seyferth Hot Springs delivers an impressive 185°F in the high desert country of Modoc County near Alturas, ranking among northeastern California's hottest thermal features. The 136-degree temperature differential reflects intense geothermal activity in this remote region.
The spring sits virtually roadside at 4,669 feet elevation, just 60 feet from the nearest access point. The high desert landscape features scattered conifers and sagebrush under expansive skies. Winter snow averaging 52.5 inches annually transforms the region seasonally, creating stark contrasts between the steaming thermal water and the surrounding frozen terrain.
The spring is readily accessible from the nearest road. Visit May through October to avoid heavy winter snowfall. The remote location requires self-sufficiency; bring water and supplies. Nearby Pepperdine Equestrian Campground offers basic facilities. Respect BLM regulations and extreme water temperatures.
Seygler Hot Springs sits on Bureau of Land Management lands managed by the Applegate Field Office. The extreme temperatures mark this as a window into northeastern California's geothermal resources, located near the transition between the Warner Mountains and the Modoc Plateau.
