"An epic canyon, Wadi Mujib serves as the last gasp of the Great Rift Valley. Where one of its many mouths opens to the Dead Sea, you’ll find the Mujib Biosphere Reserve—the lowest nature reserve in the world. Within the park, there are a series of marked trails that lead through the canyon or over the hills from the reception center, as well as stylish chalets overlooking the water that guests can book for longer stays. Winter is a particularly good time to visit for bird-watching, as flocks stop here on their migration between Europe and Africa. That being said, most people come for the chance to walk, or wade, up the canyon along the Siq Trail, a nearly two-mile path that ends at a spectacular waterfall. Don’t bring anything that can’t get wet, and know that the Siq Trail is closed in winter and early spring due to the risk of flash floods."
