Petra, the Rose-Red City, was the impressive capital of the Nabataean kingdom whose ruins remained hidden to most of the world until the Swiss explorer, JL Burckhardt, disguised as an Arab scholar, infiltrated the city in 1812. It is a UNESCO World Heritage Site as well as one of the New Seven Wonders of the World. Meet your private guide at the site and hike or ride a horse down to the entrance of the Siq, a long, winding sandstone canyon that leads to the Treasury. The tour continues to the Street of Facades, the Roman Theater and the Royal Tombs. Note that travel time is 3 hours driving from Amman to Petra and another 3 hours back.
