SaunaNor runs saunagus in a large mobile sauna on Göteborg Plads, next to the Sandkaj harbour bath in Nordhavn, from September to the end of April. Each 75-minute session has three 12-minute rounds led by a certified gusmaster, with breaks for swimming in the harbour. No membership is needed and a ticket costs 220 DKK; there are lockers but no changing rooms, so bring swimwear and a towel. Private saunagus with exclusive use can be booked.
