Tan-Tan in the context of Guelmim-Oued Noun

Cape Juby (Arabic: رأس جوبي, trans. Raʾs Juby, Spanish: Cabo Juby) is a cape on the coast of southern Morocco, near the border with Western Sahara, directly east of the Canary Islands.

Its surrounding area, including the cities of Tarfaya and Tan-Tan, is called the Cape Juby Strip (after the homonymous cape), the Tarfaya Strip (after the homonymous city) or the Tekna Zone (after the Tekna, the native Saharawi tribe). The region is presently the far south of internationally recognized Morocco, and makes up a semi-desert buffer zone between Morocco proper at the Draa River and Western Sahara. The strip was under Spanish rule during much of the 20th century, officially as part of the Spanish protectorate in Morocco, but mainly administered alongside Saguía el-Hamra and Río de Oro as part of Spanish Sahara, with which the Strip had closer cultural and historical links.

The Draa (Arabic: وادي درعة, romanized: wādī dar'a; also spelled Dra or Drâa, in older sources mostly Darha or Dara) is Morocco's longest river, at 1,100 kilometres (680 mi). It is formed by the confluence of the Dadès River and Imini River. It flows from the High Atlas mountains, initially south-eastward to Tagounite, and from Tagounite mostly westwards to its mouth in the Atlantic Ocean somewhat north of Tan-Tan. In 1971, the (El) Mansour Eddahabi dam was constructed to service the regional capital of Ouarzazate and to regulate the flow of the Draa. Most of the year the part of the Draa after Tagounite falls dry.

In the first half of the 20th century, the lowest course of the Draa marked the boundary between the French protectorate of Morocco and the area under Spanish rule.
