Bilma is an oasis town in northeast Niger, situated beneath the Kaouar Cliffs for protection from desert dunes. It serves as the largest settlement along the Kaouar escarpment and is known for its salt and natron production, date cultivation, and historic role as a stop on the Azalai caravan route from Agadez. The population is primarily Kanuri, with smaller Toubou, Tuareg, and Hausa communities reflecting its past in Trans-Saharan trade. As the administrative center of Bilma Department, the town continues its salt production while seeing growing tourism linked to Agadez and the Aïr Mountains. Bilma has a harsh desert climate, with extreme temperatures ranging from -2.4°C to 48.2°C and minimal rainfall.
