The Acacus is the name given to the mountainous region of Libya’s south-western Sahara. An officially designated UNESCO World Heritage Site, the Acacus region offers spectacular desert and mountain scenery. There is a large variation of landscapes, from differently coloured sand dunes to arches, gorges, rocks and mountains. Major landmarks are the arches of Afzejare and Tin Khlega. Although this area is one of the most arid of the Sahara, there is some vegetation, such as the callotropis plant.

It is well know for its rock art and paintings extend back 12,000 years depicting the development of human societies and the animal life that was once abundant in the Sahara, such as giraffe and elephant. Travel in this remote area is invariably in 4WD vehicles and offers the perfect opportunity to step back into pre-history.
