Harbours with saunas – by boat to the sauna
For many people, a sauna and a dip in the sea are the highlight of a boat trip. Here we have gathered our destinations with a sauna in the harbour or on the island, from Kustavi to Hamina. Choose a destination, and in its trip guide you will find the route, the travel time and directions for getting there.
Details checked against sources in October 2026.
Every sauna is different
The saunas at the destinations vary a great deal: some have a guest harbour sauna, others a shore sauna or a smoke sauna that must be booked. Sauna slots, bookings and prices vary, so check them on the destination's own website before you set off. You will find a link to the destination's website in the trip guide's sources.
Many saunas are only open in the summer season. In spring and autumn, check in advance that the sauna is open.
Destinations with a sauna
The destinations are grouped by area and listed from nearest to farthest. The travel times are our one-way estimates for the routes, and the actual time depends on the boat, the conditions and the traffic.
