When I was in Copenhagen in early November 2010 I went on a canal cruise, the one hour DFDS Guided Tour courtesy of Visit Copenhagen. It was a sunny but cold morning but I was prepared for that with my double trousers, thick fleece and hat. With all my warm garb, I was able to stay out at the front of the boat while many other passengers sought shelter in the covered, heated middle section of the boat.

I think that a Copenhagen Canal Cruise is a great way to see the city.
