Soboba Hot Springs are a historic hot springs and resort in Riverside County, California, United States. The springs issued from the side of a steep ravine "with narrow, precipitous sides, and the rock exposed is largely a crushed gneiss...the thermal character of the springs is due to crushing and slipping of the rocks". The Soboba Hot Springs resort was adjacent to the reservation of the Soboba Band of Luiseño Indians. Soboba means hot water in the Luiseño language.
