On the Mikkelipuisto shoreline, Sauna Restaurant KAIHU welcomes you.
Experience the perfect sauna in a stunning lakeside setting. The saunas USVA and KAISLA offer gentle and relaxing steam. The closeness of the water flows in through the windows and soothes the mind. It feels as if time stood still.
Between sauna sessions, you can enjoy a moment in the heated outdoor pool or refresh yourself in the sparkling lake water — with the option of winter swimming for the brave during the colder months. In summer, you can linger on the sunbeds of the downstairs terrace and admire the breathtaking scenery.
After the sauna, the Lounge Bar serves drinks and light bites, providing a cozy place to relax by the fireplace. The unobstructed view of the surrounding waters offers a direct connection to nature.
Kaihu Rooftop, the Rooftop terrace will be open next time in summer 2026. See you then!
Book your sauna session
You can reserve your sauna seat for public sessions daily through the booking service saunat.fi. We always recommend making a sauna reservation. Each sauna session lasts two hours, during which you can enjoy two atmospheric saunas, winter swimming, the heated cooling pool, as well as drinks and light snacks from the Lounge Bar. The saunas are shared-use and swimwear is required. Changing rooms are separate for men and women. You can check our opening hours and prices here.
The entire ferry is a licensed area, which means you can enjoy refreshments even in the sauna. Bringing your own drinks is not allowed. You can also purchase multi-visit passes or gift cards on-site for various needs.
Private events
Private events are organized according to existing sauna packages or tailored to suit the customer’s needs. The maximum capacity is 30 people, and currently there are three different sauna packages available. The ferry can be booked either with sauna packages or by hourly rate, in which case additional services are charged separately.
Prices start at €49/person on weekdays including catering (minimum 15 people). On weekends, a surcharge of €5/person is added to all packages.
For all additional information, please contact our sales service. The sales team is available on weekdays from 8 AM to 5 PM at +358 10 764 2000 (€0.0835/call + €0.1209/min) or via email at sales.suur-savo@sok.fi. You can find more detailed information about the contents of private events here.
Kaihu Rooftop
Kaihu Rooftop was first time open at Easter 2025. The rooftop accommodates about 80 guests, and a covered glass pergola provides shelter – so even rain won’t spoil the fun.
During the spring season, the Rooftop will be open on weekends, serving a wide variety of drinks, refreshments, and café products. As summer approaches, we’ll open the kitchen, offering fresh and vibrant salads and bowls, among other dishes.
The stunning views surrounding the Rooftop create a sense of tranquility, while the live DJ playing on weekends guarantees a relaxed and cheerful summer atmosphere. More information about upcoming Kaihu Rooftop events will be announced soon.
Sustainability
Sustainability and respect for the surrounding nature have been the guiding principles throughout the planning and implementation of the entire site.
The building’s wooden architecture and timeless design blend seamlessly into the lush lakeside landscape. The structure is built from Finnish CLT solid wood and rests on a concrete pontoon foundation, forming a unique, floating entity. The terraces feature eco-friendly Sature decking made from certified Finnish pine, and the sauna benches are crafted from Accoya wood, responsibly sourced from PEFC- and FSC-certified forests.
The furniture is made of wood and incorporates paper composite produced entirely from 100% recycled paper. The WC fixtures are from the Finnish brand Woodio and made of ecological wood composite. The sauna stoves and the fireplace in the downstairs lounge are from Tulikivi’s collection.
