Slates Hot Springs
Slates Hot Springs, also known as Big Sur Hot Springs, emerges at 122°F on the iconic Big Sur coast at just 4 feet above sea level.
The spring sits 206 feet from the Pacific Coast Highway in the Big Sur region near Carmel Valley. The dramatic coastline combines steep mountains, coastal vegetation, and ocean views, with water 60 degrees warmer than the ambient air temperature of 62°F creating a striking thermal contrast.
Thomas B. Slate filed a land patent for the site in 1882, establishing early settlement and use of this coastal thermal feature. The spring's location reflects unique geothermal activity along California's coastline where tectonic activity creates heat sources near the surface.
Access requires a short walk from the Highway 1 corridor. The coastal location means fog and moderate temperatures year-round, though winter storms can affect road access. Spring and summer offer the most reliable conditions for visiting.
