I would suggest that you travel through the islands in southern Denmark, on the way to Sweden. This is a very idyllic and pretty route. Coming from the border at Flensburg, you should drive towards Fynshav, where you have ferries to both Bøjden and Søby. Continue from one of these two places to Spodsbjerg and take the ferry to Tårs. After that drive through the southern islands of Denmark and up to Copenhagen and Helsingor where you can take the short and scenic ferry crossing to Helsingborg in Sweden. This route will take you through some of the most idyllic scenery you will find in Denmark.
