〇The temperature of the outdoor bath is low during winter. Please warm yourself up in the indoor bath before going outside.
〇The picture of the outdoor bath is the view from the men's outdoor bath. The women's outdoor bath is mainly cave-style. The bathes are switched in the evening, so over-night guests can enjoy both styles.
The beauty of nature is above the clouds.
Experience the panoramic view in a mountain top in altitude 1280m.
