Western Sahara is an area in North Africa bordering the Atlantic Ocean, between Mauritania and Morocco. Its governance is disputed between Morocco and the Sahrawi Arab Democratic Republic (SADR), but the majority of it is occupied by Morocco. While there is a large coastline, much of it is rocky and not fit for beaches or travel. Large-scale fishing and ports are at Ad Dakhla. Much of the territory is arid desert. The area near the sand wall created by the Moroccan military (also known as "the berm") is surrounded by land mines and should be avoided. Administratively, the territory was divided by Spain into two regions: the northern strip, known as Saguia el-Hamra, and the southern two-thirds, named Río de Oro.
