One of the largest natural reserves in all of Africa is in Northern Niger, surrounded by the unforgiving Sahara desert. The Aïr and Ténéré Natural Reserve is a UNESCO World Heritage Site and a wildlife sanctuary with some of the most beautiful views on the continent. You may spot some of Africa's most endangered species, like the Dorcas gazelle and Barbary sheep, among the granite mountains and rolling dunes. Bird watchers can marvel at migratory flocks coming from the Mediterranean to breed in pockets of woodland. The nomadic Tuareg clan has thrived in this extreme landscape for thousands of years, but in your case, it's best to visit this vast reserve with a tour guide from Agadez or Arlit.
