About
A free, volunteer-run sauna on Mustikkamaa, the island park a footbridge away from Kalasatama. No staff, no booking, no rules beyond basic sauna etiquette. Bring your own towel and an open mind: Helsinki at its most democratic.
Good to know
- Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
- Right on the sea: expect saltwater dips between rounds, cold even in summer.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
- Mixed sauna: men and women share the room, in every session or on set days.
- Nude sauna: some or all sessions are taken without swimwear.
- Swimwear sauna: some or all sessions are taken in swimwear, so pack it.
Hours
- Open 24 hours
- daily
