About
The only sauna boat on Lake Thun, departing from Gwatt at the foot of the Berner Oberland and running year-round in any weather. You heat up on the water with the Alps rising ahead, then jump straight into the lake to cool. Self-contained and bookable as a private session — heat, cold water and mountains, all from the deck.
Good to know
- Wood-fired heat — softer, heavier löyly than electric, and the smell of the stove is part of the room.
- Direct lake access — most visitors plunge straight into the water between sauna rounds.
- Set up outdoors — weather is part of the experience, so dress for the walk between cabin and water.
- Cold plunge available on site — use it between rounds for the classic contrast cycle.
- Bookable as a private session — rent the room for your group rather than sharing with strangers.
- Mobile operator — the sauna travels, so the location is part of the booking. Check the current site before you arrive.
