Hida-Osaka Onsenkyo, Gero, Gifu
Himeshaga-no-Yu, Gandate Gorge
Himeshaga-no-Yu is for visitors who want to feel the contrast between its roughly 22°C unheated carbonated source bath and the heated pool around 36°C. The limited weekly schedule and remote setting make advance planning essential.
Check before bathing
