Adrar Tamgak is a mountainous massif in the Aïr highlands of Niger, reaching 1,988 meters at its highest point in the southern section. Part of the UNESCO World Heritage-listed Aïr and Ténéré Natural Reserves, it features a deep, arc-shaped gorge dividing it into northern and southern sections, formed by overlapping plutons and volcanic activity. Underground water surfaces along the gorge, creating large basins, particularly in the western part. The area supports wildlife such as Anubis baboons, gazelles, mouflons, and raptors, with vegetation including acacias, Anogeissus, and lavender. Nomadic Tuareg inhabit the region, historically using the mountain as a refuge. Crossing the gorge by camel takes at least six days, first achieved by French explorer Burthe d’Annelet in 1930.
