This is no ordinary city sauna - at Seebad Enge the sauna is located on a platform floating on Lake Zurich. So when it's time to cool off, you can step out onto the pier and jump into the lake. There are three saunas, one only for women, and two resting rooms. Remember: nude areas for both sexes are common in Europe, and you usually enter saunas sans clothing, with the exception of a towel. Massages and other treatments are available and there is a café too. A very pleasant option for spending a cold winter evening in Zurich.
