PETRAThe rose-red ancient city of Petra is the jewel in Jordan’s archaeological crown. Visitors walk through narrow gorges, emerging onto spectacular 2,000-year-old relics carved into hard reddish rock—including Al-Khazneh, “the Treasury,” which was built as a tomb for an ancient king. Petra’s remains are a testament to Jordan’s importance on the spice route that wound through China, India, the Arabian Peninsula, and southern Europe. In addition to tombs, there are Roman-style theaters, sacrificial altars, and colonnaded streets. Romantics can book a candlelit evening tour complete with accompanying storytelling and pipe music.
