About 145 d f.
It's been moderated so people don't get burned. If you take a spa at Buckstaff, you'll understand. 145 Fahrenheit is way to hot to stick your hand in. The water is completely clear, no taste, no smell, heavenly!
The water is pretty boiling, 143*F or 65*C but there is an area up the mountain where it comes out cold.
I was there a few weeks ago. There are hot and cold springs. I put my hand in the hot spring, was not anywhere near getting burnt. Felt more like hot tub temperature. So, probably around 100 degrees.
Its 143 F. They do have drinking fountains with it both hot and cold
Really hot. Not quite boiling, but you shouldn't put your hands into it in the park area. It will burn you.
