The Ennedi massif lies mostly forgotten in the heart of the Sahara Desert, in northern Chad, but it shelters secret canyons with a flora and fauna of breathtaking beauty. In 1950, Hubert Gillet, a professor at the Museum of Natural History in Paris, began to explore this lost paradise. For more than a decade, he travelled through these mysterious mountains, on the back of a camel, discovering "a unique flora and fauna, relics of a golden age, which have survived in the depths of the Sahara Desert." Even today, access to the Ennedi massif is difficult, and only a few rare nomads have been privileged enough to penetrate the heart of this astounding massif. Come explore this hidden treasure.
