Natural hot spring with a square man-made pool and even a change room at the end of a long gravel road in the Santa Barbara Mountains. Visitors MUST buy a day or annual adventure pass e.g. in Santa Barbara BEFORE heading into the mountains; there are no passes or rangers available on site, but they do patrol occasionally and love giving tickets. With the pass the use of parking and camping nearby is free. A 10 minute trail leads to more natural and lesser known hot springs at the north past the end of the driveable road.
