Lonna’s public sauna is located on the island of Lonna in the archipelago just in front of the city center of Helsinki.

There are both men and women’s loft saunas which are heated up with wood burning stoves. At Lonna, you can experience the calm and almost sacred feeling of the traditional Finnish sauna. The sauna building is built solely with natural materials. It is made of masterfully handcrafted wooden logs that are left untreated.

Starting times are staggered in a way that for women and men’s sides, 12 seats are available every hour. The sauna is open from Tuesday to Saturday, with a sauna pass for two hours. Tuesdays and Fridays are designated as mixed sauna days.

Outside the saunas, there is a large terrace that opens to spectacular scenery of the archipelago. The sauna area is fully covered by a liquor license. It is always open for everybody, so unfortunately a private sauna experience is not possible. Lonna’s sauna is meant only for a peaceful and relaxing visit.

Booking the sauna beforehand is highly recommended.
