In the early 20th century there was a Swedish health movement in which nutritious food, skinny-dipping, and abstinence from alcohol played an important role. Parts of that movement are still alive—reflected in the bathing houses around the coast where nudity is a must and the water never seems to be too cold for a swim. Saltholmen Kallbadhus is a beautiful building where men and women can enjoy the sun and the sea in separate sections. You pay the fee, find a spot for your blanket or sun bed on the pier, and get ready for a naked day outside. If you are too hot, you can always climb the ladder down into the sea and cool off. Of course you can do the same things—but with swimsuits—on the cliffs outside.
