Location of the Atlas Mountains

The Atlas Mountains stretch across northwestern Africa, spanning three countries:

• Morocco – High Atlas, Middle Atlas, Anti-Atlas ranges.
• Algeria – Saharan Atlas, Tell Atlas.
• Tunisia – Eastern extensions (e.g., Djebel Chambi).

The range runs roughly 2,500 km (1,600 mi) from the Atlantic coast near Agadir to the Mediterranean near Tunis, separating the Mediterranean/Atlantic basins from the Sahara Desert.
