The whitewashed building consists of three wings enclosing a courtyard. Among the sights worth seeing are the preserved Baroque castle church (Danish: Gråsten Slotskirke) from 1699 and the castle park, laid out in 1700. The chapel and the castle park can be visited from April to October, when the royal family is away. Margrethe II and her family usually stay at Gravenstein Castle between mid-June and early August. Traditionally, the royal family arrives on the yacht Dannebrog, which is moored in front of Sønderborg Castle during the holiday weeks.

The Gejlå Bro bridge takes its name from the small stream Gejl Å, which has been crossed on a horse or by foot since centuries before Christ. Apparently the first bridge around here was built between 750 and 1050.
