Peace and relaxation await you! First, have a good sweat in one of four sauna cells, then cool down under a shower or, if you’re brave enough, jump into the lake. It’s a real treat, especially in winter (the lake is approx. 40 degrees F during the cold months). A beautiful view of the lake and the city is included in the entrance fee. Mondays are reserved exclusively for ladies. Entrance fee: CHF 27.
