Went to bathe in some warm water ponds. Don't know if we were unlucky or not, but the water wasn't warmer than lukewarm. The ponds on Iceland were much better :-)
The surrounding area was however very nice. Drove through a jungle to get there, and it was located on the coast. Huge waves were crushing against the breakwaters.
Might go there again before we continue to Mauii, but next on the list is probably the volcano park.
