This electrically heated barrel sauna stands by a sea strait at a wake park in Helsinki, with easy and safe access to the water for cold dips. You can alternate between heat and cold water at your own pace, so it suits first-timers and seasoned open-water swimmers alike, as well as groups of friends and workplace outings. Up to six people can use it at a time.
Book online by choosing the number of people, the date and a time slot. The same website also offers wakeboarding, SUP and foilboarding sessions, and it is available in Finnish and English.
