10月三連休の日曜日、お昼頃伺いました。駐車場は満車に近かったですが、すぐに入場できました。まだ紅葉には早かったですが、温泉が噴き出している様子が間近で見られ、素晴らしかったです。少し肌寒い日でしたが温泉の蒸気と階段の上り下りで身体が暖まります。下った分帰りは階段を上らないとならないので、足に自信が無い方はキツイと思います。

日本広しと言えどこんな温泉が出る渓谷は無く素晴らしい体験ができます。紅葉時期はもっと素敵でしょう。工事関係者の方々、ありがとう御座いました。入口にある杖を利用して下さい

階段でかなり降りたので少し疲れたなーと思っていた所に川から湯気！一気に熱気溢れるエリアに入り不思議な感覚でした。とても神秘的な絶景スポットでした。帰りはかなり階段を登るので覚悟が必要です。貸出の杖があるので不安が少しでもあれば使うのをおすすめします
