Ipla is the hottest of the termas (thermal baths) with a direct channel of thermal water practically going straight to the large public baths. The Barros El Chino is where you can relax covered in therapeutic mud, bake it off on the drying rack, and then wash clean in the plunge pools. There are basic changing facilities, showers, and a snack bar.
This fountain near the Baños Ipla has slightly radioactive spring water (because it occurs naturally, it's fine to bathe in but not drink), which is said to cure every type of eye malady.
