⛵ Helsinki Sauna Ferry — floating sauna ferry in the Helsinki archipelago

Helsinki Sauna Ferry is a floating sauna operated by Helsinki By Sea, offering year-round cruises in the eastern Helsinki archipelago. On board you’ll find a wood- or gas-heated sauna, a lounge area, a dining table, a fridge and an outdoor deck where guests can dip into the sea during stops. The concept is tailored to private groups, from corporate events and birthdays to parties and seasonal gatherings.
Guests choose a route among the islands, combining sauna sessions, Baltic Sea swims and scenic archipelago views. It’s an option for those looking for a more unconventional sauna experience on the water instead of a traditional city sauna. Tried Helsinki Sauna Ferry already?
