You have a few options depending on from where in Sweden you are driving. If you are close to Malmö, the Öresund bridge is your best choice. This fixed link connecting Sweden and Denmark is one of the largest constructions, of its kind, in the world. It is a combination of a bridge, an artificially made island, Peberholmen, and a tunnel. All together 16 kilometres (10 miles).

It is a 30 minutes drive from city to city. From Helsingborg there are ferries running 24 hours a day to Helsingør (Elsinore). The crossing takes 20 minutes and Copenhagen is within less than an hour drive.
