Visiting one of the Caucasus’s oldest settlements ranks among the best places to see in Azerbaijan. With a population of just 60,000 at the foot of the Greater Caucasus Mountains, the humble impression outsiders get is somewhat deceptive. For millennia, Sheki’s silk transformed the small town into a major post on the Silk Road. Traders from east and west converged here with many sleeping in the town’s caravanserai. Flash forward and find the Palace of the Sheki Khans from the 18th-century, castles and historical mosques. Head away from Sheki and find rivers, waterfalls, and gorges along with several opportunities to hike in the mountains.
