On hot days, Copenhageners swim with the city’s skyline in free view. During the week, many locals pass the pool for a quick dip on their way home from work. The quality of the water is checked daily and has to be approved by the authorities before swimmers are let in. There are five pools in all, two of which are specifically for children. The shallowest pool is 30 cm deep. The diving towers are one, three and five metres high respectively. During the winter period you may catch a glimpse of local winter bathers.
