The Bardenas Reales is a semi-desert natural region, or badlands. It is about 42,000 hectares (100,000 acres) and is located in southeast Navarre (Spain). The soils are made up of clay, chalk and sandstone. They have been eroded by water and wind. This has created a number of shapes, canyons, plateaus, tabular structures and isolated hills, called seamounts. Bardenas lacks urban areas and vegetation is scarce.
