It has been a few years, since I have been there. I believe it is Spencer Hot Springs; east off of NV Hwy 376 (it runs between Tonopah and US 50 east of Austin, NV. The turnoff to the HS is just a few miles south of US 50 to the east. We traveled a few miles on a dirt road (just go slow and easy). Three good size water tanks to soak in. Volunteers put a movable flute at each tank so you can adjust the water temperature. That was our overnight stop on the way to Burning Man. Only once did we encounter people other than our group. If you have a source to find hot springs you can get the GPS numbers. If you find it pass on the GPS numbers to me. Good luck. The temps should not be too high. We were late August warm days and cool nights.
