About
A free, volunteer-run sauna on the Sompasaari waterfront: no staff, no booking, no rules beyond basic sauna etiquette. Built from salvaged materials and open around the clock in summer. 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.
