The dunes in this national park are unique and not to be found anywhere else in North Western Europe. Its sands are always moving. At the end of the 19th century woodlands were planted around the 'drifting lands' to control this unusual movement. On the south side of the park lies the De Brand marshland. Although very beautiful in autumn and winter, the best way to explore the Loonse and Drunense Dunes is on foot or by bike in spring or summer.
