There are many living root bridges scattered across the dense valleys of Meghalaya’s Khasi Hills region, but the most spectacular and arguably the most famous is the Umshiang double-decker bridge, which is more than 180 years old. It is found just outside Nongriat, a small village that’s reachable only by foot, about 10km south of the town of Cherrapunji. The bridge’s two levels span the Umshiang River, and local villagers are adding a third level, hoping it will further attract tourists. (Neelima Vallangi)
