"Wear your shoes, those rocks are tough.
What a delightful onsen though. I found the temperature to be perfect, although there did seen to be a jet of extremely hot water coming out through the wall, so beware of hot spots.
The view was superb. The mosquitoes did arrive as the sun was setting though. I wish I had brought some mozzie coils.
Highly recommended."

"We weren't sure where we were heading, but once we found it, it was an unexpected delight. An onsen right on the beach! The temperature is perfect, but be careful near the west wall as some very hot water seeps through."
Doron Houminer
"Was sad. We had a hard time finding the onsen. Then we realized it was completely covered with stones and kelp, no way to enter. You can only feel the heat with your legs when you stand nearby"
