Essendilene is an uninhabited oasis in the Algerian Sahara, belongs to the Tassili Cultural park, the largest of the Algerian National Parks and is located in Tassili n'Ajjer Canyon, about hundred kilometres northwest of Djanet.
In colonial times, a small military fort was built at the entrance of the canyon, and it served as a basis for Roger Frison-Roche's novel, ‘Essendilene's Rendezvous,’ written in 1954. The disused building still exists today.
The hamadas are tabular rock plateaux limited by cliffs. They are from the sedimentary origin, generally limestones. When they are covered with sandstone, they are named tassilis.
