A Finnish sauna experience at Seebad Friedrichshagen
Book your sauna timeIn Finland, the sauna is more than a place to work up a sweat. It brings people together for good conversations, shared moments and relaxation in nature. Together with Seebad Friedrichshagen, we bring this feeling to Lake Müggelsee with Lappi - Outdoor Spa.
Experience our mobile sauna tent right by the water. Enjoy comforting heat of up to 90 °C, crisp winter air and the chance to cool off in Lake Müggelsee after your sauna session.
Ideal for cold-water swimmers, sauna lovers and anyone curious to try something new.
Places per session are limited. Book your place here in advance. If spaces are still available, you can also book on site.

For shared sauna time, you book a place for €15 per person and may share the sauna tent with other guests. If you prefer to have the tent to yourselves, you can book the whole tent for €60 per 60 minutes for private use.
The sauna is most comfortable with up to four people at a time. You can also come as a larger group. For example, a group of six can take turns during the booked time. A maximum of four people can be inside the tent at any one time.
Inside the sauna tent, you can choose whether to wear swimwear or use the sauna without it. Always sit on a towel.
Important when swimming in Lake Müggelsee: Seebad Friedrichshagen is not a naturist swimming area. Swimwear is therefore required if you want to swim in the lake after your sauna session.
Please bring at least two towels: one to sit on in the sauna and one to dry off with. You will need swimwear if you want to swim in Lake Müggelsee.
Sandals or flip-flops are useful for walking between the sauna and the lake. Bring warm clothes for afterwards and, in cold weather, a hat or other head covering.

The sauna tent stands right by the lakeshore at Seebad Friedrichshagen. During our sauna sessions, the Eisstrand winter venue also operates its ice rink, ice stock sport and snack bar. The area around the tent can therefore be lively, with other visitors passing by.
For a completely private outdoor sauna experience at a location of your choice, you can instead rent one of our sauna tents for collection and set it up at your preferred location.
