Verkkosaarenkuja, Hermanninranta, 00580 Helsinki

Sompasauna is a woodheated self-service public sauna, built and maintained by a group of volunteers. Visitors enjoy the sauna and swim in the sea at their own risk; there is no lifeguard or staff on-site.

The sauna is open around the clock and free for everyone to use.

NB! The sauna will be moved from Sompasaari to Hermanninranta right after Midsummer 2021.

Sompasauna is closed from 28.12.2021 due to corona restrictions.
