Jump in the harbour for a swim at Copencabana harbor swimming bath. There is a jumping tower for fun, and a large pool, with sea water from the harbor. Not as popular as the larger harbor swimming bath at Islands Brygge, Copencabana is less overrun and better suited for more serious swimming.
Small museum of toys and dolls, dating all the way back to 1840 and up to 1930s.
Old cattle market turned exhibition hall, in the up and coming Kødbyen sub district (see section below). Various changing exhibitions. The website schedule is in Danish only.
The Swim Centre
If you are installed at a cheap hotel without private baths or want some inside activities on a cold or wet day, the swim centre, or DGI-byen as it is known to all locals, is a good option. No time-limits, super-ellipse shaped pool, climbing and diving pool, warm spa pool, and other water activities.
This museum, run by B&W, houses what was the largest diesel engine in the world for around 30 years. Nowadays it has a lot of diesel related exhibits spread over three floors, especially to do with ships - all very well presented. The volunteers are retired B&W employees and are very friendly. They run the main engine every 1st and 3rd Sunday of the month, plus on some other occasions as advertised on their website. There's a small gift shop where you can buy t-shirts, notebooks, etc. They ask that you email ahead if you want a guided tour.
The New Theatre
One of Denmark's top stages, usually lays stage to famous musicals or plays like Chicago, Phantom of the Opera etc, but the performance may in Danish so check ahead. The striking building is one of the most beautiful theatres in Northern Europe following a grand renovation in the 1990s, and received the prestigious 'Europa Nostra' award for the efforts.
