My favorite hot spring in Mammoth! One of the easiest to get to. Came on a Monday Nov 14- tub was full & HOT almost TOO hot. The valve was left wide open which made it too hot to go full body :(
To be mindful of others' experience, leave the valve 3/4 of the way closed to be able to adjust the temp as desired.
Bring a towel/robe. Very relaxing spot & quiet. Love it here!
