Lake Yunoko and its loop walk, Yudaki Falls at the lake’s outlet, the Senjogahara marsh trail down to Ryuzu Falls, and the hot-spring source fields behind the village.
Yumoto is at about 1,500 metres: snow lies here from December, and some evenings are cold even in summer. The sulphur smell is strong; it is part of the deal.
