not the best experience, but definitly not the worst. Insanely crowded at all times of the night/day, but that is to be expected considering how close to town it is. the hot water is REALLY hot. but quite nice as long as you dont move around to much. the lukewarm seemed cold after being in the hot for a few minutes. they clean all three pools every day at 4, so the muddy tinge to the water ois just how the water comes out of the spring. they also have an ingenious system of piping water in from the near by waterfall, which consists of gutters and pipes with holes in the top just braced out in the middle of the waterfall. this water is very clean and very cold, and it is quite an experience to go from the hot pool and drop directly into one of the cold ones or the cold shower.
make sure you bring 30 extra cents to buy a required shower cap, and dont bring any valuables, because while they DO have a lockup, it didnt look that secure.
