A mountain cabin-style far-infrared dry sauna installed in the outdoor area. It has a single-tier layout and a very dry setting, with the room temperature around 95°C. The perceived temperature varies greatly depending on where you sit; if you position yourself in front of the stove you will feel very intense heat and can start sweating profusely all at once. Bringing drinking water into the sauna is permitted.

The cold plunge bath is located in the outdoor area immediately outside the sauna. It uses mountain spring water from the foothills supplied in a free-flowing manner, and this water is drinkable. The water temperature varies by season but is around 16°C–21°C, making it very mild and pleasant. While listening to the river's babbling below, you can enjoy an exquisite cooldown.
