Fee: $5 per person/2hr soak, honor system drop-box.
Shelter: nearby 2 RV parks
Directions: On CA 70 about 5 miles west of the CA 89 junction. Look for two big logs in front of an old cabin with a chimney. This is west of a small RV park that is west of a bigger RV park called Crystal Springs.
Update Jan 2013: hot springs are open to those staying in R&R RV Park or in one of the 3 cabins. Call the Owner Rocki at 925-783-2913 to make reservations or visit http://www.randrrvparkhotsprings.com/
For day-use (2-hr soak), the entry is $5/person, which is paid at the drop-box. By keeping the springs clean and supporting the owner's efforts to maintain a nice facility, then these wonderful soda and sulfer springs can remain open.
