Winter Island

Winter Island is a floating platform on Kalvebod Brygge, eight minutes' walk from Copenhagen Central Station, with four saunas for 8 to 10 people and the 30-person Horizon sauna, all with panoramic windows over the water. A place in a shared sauna costs 150 DKK per hour with no membership needed, whole saunas can be hired privately, and saunagus runs in Horizon. Cooling is by cold showers and splash buckets, since swimming from the island is not allowed.
