Outdoor Saunas in Helsinki (2026 Guide)
Helsinki's outdoor saunas are as much about the setting as the heat. Löyly's outdoor terrace extends over the Baltic with a swim platform and sun deck; Allas Sea Pool's rooftop adds an urban panorama over Market Square. Sompasauna on the east harbour is an entirely outdoor community sauna — open-air, volunteer-run, free. In winter, outdoor Helsinki means sub-zero air, steam rising off the sea, and occasional sea ice underfoot.
