Petra

Established in 312 A.D., Petra was lost to the sands of time until 1812. Today, this city -- located in the southwestern desert of Jordan -- is well preserved and not all of it has been excavated. Archaeologists found a ceremonial platform in June this year, thanks to satellite and drone images. Travelers can access Petra any time of the year, except during the winter when floods threaten the safety of tourists. It's fairly hot, so bring plenty of water, sunscreen, and protective layers.

Arrive at Petra via bus, taxi, or rental car. Visitors must buy entry passes in the nearby town of Wadi Musa. From there, walk through the Siq -- a narrow gorge that’s over a half-mile long -- to Petra. Horses and carriages can be hired to pass through the Siq. Although visitors are welcome to explore the area on foot, camels and donkeys are also available within the ancient city to carry tourists to various sites. Entry prices will run you about $70 for a one-day pass.

Keep in mind: The conflict in neighboring countries like Iraq and Syria have brought Petra's tourist numbers to an all-time low. At the moment, however, Petra is safe. With fewer crowds, this may be a great time for travelers to visit.
