12. Petra, Jordan
Located in western Jordan snuggled away in an isolated valley you will find the mysterious ancient city of Petra. This magnificent city was carved in sandstone cliffs by an Arab tribe, the Nabateans. The high walls and surrounding mountains served as an intimidating defense against raiders. The city has remained well preserved so it is easy to imagine the city as it once was. The colors of the rocks offer an amazing display and catching your first glimpse of the iconic Treasury is a moment you will not forget.
