Lähteen Sauna
Helsinki, Finland

About
An 1880s sauna in the Lapinlahti hospital park by the sea, reckoned to be the oldest public sauna still working in Helsinki. Mixed, women's and men's shifts run through the month with no booking; you turn up and pay at the door. The whole sauna can also be hired privately, and the beach is under 100 metres away.
Good to know
- A historic sauna with heritage worth the trip on its own, whether the building, the tradition, or both.
- Urban venue: it sits inside the city rather than at a coast or lake. A session fits into a day in town.
- Right on the sea: expect saltwater dips between rounds, cold even in summer.
- Bookable as a private session: rent the room for your group rather than sharing with strangers.
