Make like a Little Mermaid
Word to the wise: Some of the pools at Islands Brygge are designated for children or for jumping. Ask the lifeguard if in doubt which one is suitable for you.
Until 10 years ago, it was ill-advised to take a dip in Copenhagen's polluted harbour. Now, after an extensive clean-up, outdoor swimming is viable - and hugely popular.
There are currently three harbour baths in the city, and on a hot day what seems like most of the city decamps to the one at Islands Brygge, which has five pools and a 600-person capacity. Also popular is Copencabana in Havneholmen. The baths are open in the summer months, usually between June and September, and are free.
If you prefer some sand between your toes, there are several good beaches to the north of the city in the area known as the Danish Riviera. Bellevue beach at Charlottenlund is a good bet, and accessible on the local S-train from the city.
