The landscape on Rømø consists mainly of beach, dunes and clay grounds. There are large, undisturbed nature areas on the island and a major part is protected.
Rømø has a large flat beach between 1 and 4 kilometers wide. The beach stretches out in a westerly direction. There are also various rows of dunes on Rømø, the most easterly being the oldest. A sand dike was constructed in the 1870s west of the Vriby plantation and the salt marshes, meant to combat further silting up of the marshes. The eastern dunes were kept from blowing away by forestation. The dune woods are mainly made up of black pine but is being replaced nowadays by deciduous trees for greater diversity.
Wind erosion of the younger dunes is combated by planting marram grass. There are sandy clay grounds located between the western row of dunes. The ground is many used for farming in the south. The clay ground on the marshes in the north is used by large numbers of birds. Lakes surrounded by reed are in the middle part of the island. On the east side lie the clay polders and marshes which are intensively used for farming. A large part of the clay grounds is pasture. South of the Havneby lie several outer marshes not in use by the farmers. The marsh ends by Kongsmark in a cliff around 1 meter high that is continually crumbling.
The farmland plains in the north and south of the island are surrounded by dikes. The dikes were built in the south in 1867 and 1962 and the Juvredike in the north in 1928. When the Rømø dam was constructed, the Juvrepriel shifted north of the island, which consequently threatened the Juvredike. This dike had to be shifted inland in 1965.
