I went there once and was disappointed-- there's a lot of dark flowstone around the various pools but the water seemed to be saturated with iron and wasn't very pleasant to look at plus it had a strange feel to it, the opposite of the slippery feel associated with alkalai. If you ran your hand along your skin it didn't want to slide. I've never felt water like that before and hope to never again. Not recommended.
There was a spring in the guidebooks near the town of Meadow which is free. It's a small hole in a meadow very very deep with crystal clear warm water which was delightful. Go there instead.
