Why choose Sønderborg?
The region combines borderland history with water on several sides. Couples can celebrate near Sønderborg Castle and the harbour, choose the palace-town atmosphere of Gråsten or use Nordborg as a base for the island of Als.
It is particularly convenient for couples travelling by road from Germany, while still feeling distinctly Danish.
