This morning, travel by minibus to Mt Nebo – the place where the prophet Moses is said to be buried and where he saw the 'Promised Land'. Check out the mosaics inside its fourth-century church. On a clear day, the views over the Dead Sea to Israel and the Palestinian Territories are spectacular. After, drive to the super salty Dead Sea – sitting well below sea level, this is the lowest point on earth, and you’ll float rather than swim due to the high salt count. The mud on the sea floor is said to have healing properties, so maybe lather up and enjoy Mother Nature’s spa. Continue to the crusader castle of Kerak, sitting on top of a cliff overlooking the town and valley below. Explore the seven-level fortress and learn the legends of 12th-century battles between Crusaders and Muslim armies, then continue to Petra for the night.
