On the serene island of Lonna in Helsinki's archipelago, Lonna Sauna offers a unique and tranquil Finnish sauna experience. The two loft saunas, heated with wood-burning stoves, provide a calm and almost sacred atmosphere. The sauna building, crafted from untreated wooden logs, embodies a natural, handcrafted charm.

Sauna sessions are staggered, accommodating 12 guests per hour in separate dressing rooms for women and men. Open from Tuesday to Saturday, the sauna pass grants a two-hour retreat. Every day is a mixed sauna day, fostering a welcoming atmosphere. The expansive terrace overlooks the breathtaking archipelago, creating a perfect setting for relaxation. Lonna Sauna, covered by a liquor license, warmly welcomes everyone for a peaceful and rejuvenating visit. Booking is highly recommended.
