Welcome to our sauna!

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. You can experience calm and almost sacred feeling of the traditional Finnish sauna.  Sauna building is built solely with natural materials. It is made of masterfully handcrafted wooden logs that are left untreated. Both saunas can accommodate up to 24 guests at a time. Starting times are staggered the way that for women and men’s sides, 12 seats are open every hour. Sauna is open from Tuesday to Saturday. Sauna pass is for two hours. Outside the saunas, there is a large terrace, which opens to spectacular scenery of the archipelago. Sauna area is covered by liquor license.

Mixed sauna day is every other Tuesday. Both our saunas will be in use for all the genders. There will be separate dressing rooms for men and women. Bring your swimsuit if you want. Mixed sauna Tuesdays are May 8th & 22nd, June 5th & 19th, July 3rd, 17th & 31st, August 14th & 28th and September 11th & 25th.

Sauna fee is 16 euros / guest and the pass is for 2 hours. Children under the age of 12 can enjoy saunas without charge. Charge includes soap, shampoo and seat cover. Towels (€7) can be rented separately from the reception. Reception is located at the old guard house next to sauna.

We recommend booking the sauna beforehand. Please arrive a bit ahead of your reservation time.

If you feel like swimming we highly recommend taking suitable shoes that you can walk to the sea with. Path to the swimming area is quite rocky.
