If you like onsen, don't miss this enormous outdoor hot pool in the park. Plenty of well placed and confortable seats. The water coming in at the top is blazing hot.

Although it was snowing lightly, we have really enjoyed the easy hike. The park entry is free and there is also a free foot bath, so bring along a towel with you. There is also a public onsen, 600 Yen per person.
