About Sauna & Sea

The sauna stands on the car-free right side of the beach, a few steps from where you leave the car behind the posts. It burns timber from FSC-certified forests, and water poured over the stones around the stove gives löyly, the Finnish burst of steam and heat. On days too windy for the awning, changing moves to Harrys Shack at the beach entrance, which is also where you can get a drink once the session is over. Hen and stag parties, sports teams and sea swimming groups are regular bookings.
