Petra is a two thousand years old city carved in the rocks of Jordan, once a gateway on the silk road, and now one of the seven wonders of the world. The best experience is to walk the canyon that leads to the pink city in the night, like ancient traders and merchants. from the dark, here it comes the treasury, lighted by hundreds of candlelight: this is as close as you can get to time travel, and truly an unforgettable lifetime experience.
