This hotspring is in a midle of nowhere.. Definately hard to find but it’s worth it. You will have to drive around half an hour through lava fields via bad contition gravel – mud roads. The spring itself is small. I would say 5-6 persons max. If you find it you will have your own private natural hot spring because it is not a touristic place.
