This sulfurous hot springs is known to soothe muscle aches and pains, as well as cure rheumatism and skin diseases. The volcanically heated water bubbles up from under the lake in several places among the lava rocks. The water is not really that hot, though it becomes warmer as the day progresses. A private hot springs lies north of Amertha’s. Admission fee of Rp300 just to look, Rp1000 for hot-tub style baths. Facilities include changing room and toilet. Bring your own towel. Signs ask patrons not to wash clothes, shampoo, or wear shoes in the bathing area. Be warned, the pool is untidy and unappealing, not that private, and swarming with vendors.
The public air panas is on the other side of Amertha’s and free. However, since villagers wash their clothes and cows in these shallow pools, and there’s lots of litter around, you don’t always feel like bathing here. After a long, relaxing dunk, swim Finnish-style from the mineral pools straight into the chilly lake. Very therapeutic, especially fresh from a hike up Gunung Batur.
