Dueodde is a beach in Denmark on Bornholm's southernmost tip. It is known for its very fine white sand. The area around Dueodde was originally a large sandy area. In the eighteenth century it was planted with pines, as well as Ammophila and Leymus grasses to reduce sand drift. Today, Dueodde is a protected area. The sand at Dueodde moves easily with the wind to form dunes. The vast dune area and associated sandy beach start at Haslemere extending some 30 kilometres (19 mi) almost without interruption. Apart from the beach, one noteworthy feature is the Dueodde Lighthouse on the southern tip. It is the tallest on the island. Built in 1962, it offers a panoramic view of the surroundings. The two old lighthouses, Dueodde Syd (next to the new lighthouse) and Dueodde Nord are not open for the public.
