Niger

For those who have been lucky enough to visit, Niger is a desert republic filled with ancient caravan cities at the edge of the Sahara. 

In the north, the stark splendor of the Aïr Mountains hides Neolithic rock art and stunning oasis towns. Within the expansive dunes of the Ténéré Desert are dinosaur graveyards and deserted medieval settlements, while to the south is the ancient trans-Saharan trade-route town of Agadez and the sultanate of Zinder.
