Sespe Hot Springs surfaces near boiling, hot enough to scald, inside the Los Padres National Forest in Ventura County. Fillmore is the nearest town at around fourteen miles. Getting to the springs means a hike of a bit over four miles from Mutau OHV Road. Open access, Forest Service land.

Location

Backcountry national forest at around three thousand feet, with a short rainy winter, a little snow in the average year and dry weather otherwise. The hike in starts from Mutau OHV Road, an off-highway vehicle route by its name. Goldhill Camping Area, about eight miles out, is where the record puts the closest camping.

Winter is the listed season. Plan for a hike of four-plus miles each way and check the condition of Mutau OHV Road before you go. The source water is scalding and will burn skin on contact; only get in where it has cooled, and test first every time. Goldhill is about eight miles away. No fee is listed.

Heat Below
117 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 69% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
