The Ennedi Plateau, located in northeastern Chad within the Sahara Desert, is a vast sandstone massif covering approximately 40,000 square kilometers, comparable in size to Switzerland. Over millennia, wind and water erosion have sculpted the landscape into dramatic formations, including cliffs, natural arches, and deep canyons. This remote region is also home to one of the world's largest concentrations of prehistoric rock art, with over 650 sites dating back to 7,000 BC, reflecting its rich cultural heritage. Despite its arid environment, the plateau supports diverse flora and fauna, sustained by permanent water sources in its larger canyons. Recognized for its unique natural and cultural significance, the Ennedi Massif was designated a UNESCO World Heritage Site in 2016.
