Saltholmens Kallbadhus is a cold-water sea bath at Saltholmen, open since 1908 and run since 1976 by a members' association of about 1,700 nude bathers, winter swimmers and sauna enthusiasts. The sauna is for members only, on separate women's and men's times, and outside June to August needs a sauna add-on (400 SEK a year). Day visitors (100 SEK, summer) may use the bath but not the sauna. Everyone bathes nude, from rocks, sandy beaches and jetties with steps into the sea.
