Sompasauna
Helsinki, Mustikkamaa
A free, volunteer-run wood-fired sauna beside the sea on Mustikkamaa. Mixed and clothing optional, with a deliberately simple, self-service setup. The community looks after the saunas themselves, making this a hands-on seaside sauna experience rather than a staffed spa.
Nudity policy
Clothing optional
Naked or swimwear both welcome in sauna and for swimming. Mixed use, without separate gender sessions. Photography is prohibited.
Facilities
Bring drinking water, towel and your own padlock. No running water, showers or changing rooms. No staff or lifeguard.
Access & visiting

Age & supervision

Directions & Parking
Getting there
Use the current address Kansanpuistonpolku 5, 00570 Helsinki, on Mustikkamaa. The island can be reached across the bridge from Kulosaari or the pedestrian/cycle bridge from Kalasatama. Older Sompasauna references may point to previous sites; check that your route ends on Mustikkamaa.
Parking
There is no car access to the sauna itself. The operator names two nearby options: the Mustikkamaa Sports Park parking lot and the parking lot at the beginning of the bridge between Kulosaari and Mustikkamaa. Leave the car in a permitted bay, obey current signs and continue on foot; these are approach parking areas, not parking beside the sauna cabins.
Finding the naturist area
From the bridge or parking area, use the island’s public park paths and the Kansanpuistonpolku 5 map point to find the seaside sauna grounds. This listing’s pin is the current City of Helsinki sauna point. The public Mustikkamaa beach is a different destination; its showers and changing facilities are not facilities at Sompasauna.
Where naturism applies
Nude and swimwear use are both welcomed at the mixed sauna and for swimming there. This does not designate all of Mustikkamaa or the public beach as a naturist area. Keep normal clothing on for the approach through the public park and follow the sauna’s current site notices.
- Bring drinking water, a towel and your own padlock: there is no running water, shower or changing room at the sauna.
- There are no staff or lifeguards. The operator says the site is not accessible, though a ramp for the Temppeli sauna can be arranged if needed.
- No photography at the sauna.
Access guidance checked 2026-11-10. Follow current signs and any instructions from the venue or land manager.
