Tassili n'Ajjer National Park
A UNESCO World Heritage Site, this vast plateau in the Sahara features over 15,000 prehistoric rock art paintings and engravings dating back 10,000 years. The dramatic landscape includes stone arches, canyons, and sand dunes, creating an otherworldly environment.
Tassili n'Ajjer is a vast UNESCO World Heritage Site in the central Sahara of Algeria, covering approximately 72,000 square kilometres of the Illizi Province in the far southeast of the country. The park encompasses one of the world's most important repositories of prehistoric rock art, with an estimated 15,000 paintings and engravings discovered across the plateau, dating from approximately 10,000 BC to the first centuries AD. The art documents successive periods of Saharan human habitation — including the Bubaline, Round Head, Pastoral, and Camel periods — and includes depictions of animals now absent from the region, such as hippopotamuses, elephants, and crocodiles, offering a remarkable record of an era when the Sahara was far wetter.
The physical landscape is equally extraordinary: Tassili means 'plateau of the rivers' in the local Tuareg language, and the elevated sandstone massif has been carved by millions of years of wind and water erosion into a spectacular terrain of rock pillars, arches, canyons, and mushroom-shaped hoodoos. The Cyprès du Tassili, a grove of ancient Saharan cypress trees (Cupressus dupreziana), represents one of the world's most isolated tree populations, with individual specimens estimated at over two thousand years old. Sand dunes at the plateau's base offer a dramatic contrast with the eroded rock formations above.
Access to Tassili n'Ajjer is through the gateway town of Djanet, reached by air from Algiers or by long overland road from the north. All visitors must be accompanied by a licensed guide and travel with an authorised tour operator; independent access to the rock art sites is not permitted under Algerian law. Multi-day trekking expeditions of three to seven days are the standard format, camping on the plateau and visiting multiple rock art galleries and geological formations each day. Camel and 4WD combinations are used depending on the terrain.
The park is best visited between October and March when temperatures are bearable; summer months regularly see temperatures above 45°C on the plateau, making trekking genuinely dangerous. Physical fitness adequate for four to six hours of walking per day on uneven terrain is required for the standard expedition routes.
