A hidden guelta — a permanent rock pool fed by seepage — deep in a sandstone canyon on the Tassili plateau, about 100 kilometres from Djanet. The pool sits in a narrow gorge surrounded by towering rock walls, and the water supports a surprising micro-ecosystem: oleander bushes, reeds, and even a population of Saharan crocodiles that survived here until the 20th century.
The canyon walls around El Ihrir are covered with prehistoric rock art — some of the most accessible paintings on the Tassili. The combination of water, shade, and art makes it one of the most memorable stops on a Tassili trek. Reaching it requires a multi-day guided expedition from Djanet. There are no facilities — you camp in the canyon and carry all supplies.
