Unlike the other nudist beaches, the beach is segregated for men and women separately with no unisex nudist area.The island of Seurasaari is a popular outdoor recreation area and open-air museum.

To begin with people had to take a boat to the island, but a bridge was built in 1892. Seurasaari receives tens of thousands of visitors a year. The Midsummer celebration is particularly popular.
