Vallisaaren Rantasauna offers a unique sauna experience in the heart of Helsinki’s most beautiful archipelago nature. This atmospheric seaside sauna invites you to slow down, relax, and enjoy the heat of the Löyly just a stone’s throw from the open sea.
Located in a peaceful spot on the southeastern shore of Vallisaari, right by the water, the sauna allows you to cool off between sessions on your private terrace, take a refreshing dip in the sea from the pier, or simply sit back and admire the surrounding island scenery. The warm and intimate atmosphere makes it perfect for groups of friends, families, and work teams alike.
The sauna is available for private bookings and will be pre-heated upon your arrival, so you can focus on what truly matters — relaxation and time together. Facilities include a small changing room and a separate washing area, ensuring a comfortable and unhurried sauna experience. If you forgot your towel, no worries — towels are also available for rent on site.
Enjoy a moment that feels like a summer cottage getaway — even though you are only a 20-minute boat ride from Helsinki city center.
