For cooling down you get a cold plunge bath and the small stream right in front, which runs clear. Swimwear is worn, and the sauna is by reservation only. The site also has a children's exploration play program and a cafe with a few curries and soft drinks. Free parking. This is a sauna, not a hot spring bath, and no onsen water is mentioned.
