Arguedas is a town and municipality located in the province and autonomous community of Navarre, northern Spain.

In the area is Bardenas Reales which is a semi-desert natural region, or badlands, of some 42,000 hectares (100,000 acres) in southeast Navarra (Spain). The soils are made up of clay, chalk and sandstone and have been eroded by water and wind creating surprising shapes, canyons, plateaus, tabular structures and isolated hills, called cabezos.
