Very Hot Source, Use Extreme Caution

At 144°F, the source water at Tassajara Hot Springs is hot enough to cause burns. Some hot springs this hot have cooler side pools or downstream areas suitable for soaking. Always test the water temperature before entering.

Tassajara Hot Springs is a group of natural hot springs in the Ventana Wilderness, Monterey County, on Los Padres National Forest land, eighteen miles or so from Soledad. The source water is scalding, well past the point where it burns skin, far too hot to enter without cooling. Resorts have operated here in one form or another since 1868. Access is open on record.

Location

A few hundred yards from a route listed as Tassajara Path. Around two thousand feet, in the Santa Lucia Range, with twenty-three inches of rain and an inch of snow in a typical year. The yearly average is near sixty.

February, December and January are the favored months on file. Arroyo Seco campground is under four miles away. The source is scalding; do not touch it untested, and keep children back. No fee is on record, though the site has a long history as a resort, so check current arrangements before you go.

History of Tassajara Hot Springs

The springs have been the site of various resorts since 1868. A horse trail served them until 1886, when a stagecoach road was built over Chews Ridge to reach them. They sit within the Ventana Wilderness of the Santa Lucia Range.

Heat Below
114 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 65% 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.
