• Open harbor water in the main zone, so it suits confident swimmers; younger kids are better off in the dip pool
• A fixed-bottom dip pool about 1.2 meters deep that holds up to 12 people at a time
• Check the water first on badevand.dk, the city's bathing-water forecast for water quality and weather

Kalvebod Bølge is a wooden boardwalk that rises and dips in waves along the harbor, designed by JDS Architects and Urban Agency. Its swim zone is a marked stretch of the harbor with direct access to the water.

Inside the zone sits a small dip pool with a fixed bottom, 3 by 3 meters and about 1.2 meters deep, which the city calls suited to kids in summer.
