Sauna am See Uster

Sauna am See is located in Strandbad Uster in Niederuster, right on the shore of Lake Greifensee. In winter, the lido turns into a small sauna village of wooden barrels and yurts. Since the 2025/26 season, the facility has been run by the Zurich-based Tonttu GmbH, which has also operated Seebad Enge with its Sauna am See since 1999 and Sauna im Norden in Oerlikon since 2023.

The experience is simple and close to nature: two of the three barrel saunas are wood-fired, the windows look out over Lake Greifensee, and cooling off takes place directly in the natural lake. Between rounds, guests warm up by the wood stove in the yurts. For the Aufguss sessions, the team blends natural essences to suit the season.

No reservation is required, but two to three hours should be planned for a visit. For legal reasons, the changing rooms and showers are unheated; bathrobes and sauna towels can be rented, and it is best to bring your own bathing shoes. The reception yurt offers organic tea, vegetarian and vegan soups from the Zurich bicycle courier «Suppen und Pedale» as well as snacks; once a month, on a Saturday, a Winter Day Retreat with yin yoga and sauna takes place.
