When hiking around Petra, I came across thousands of caves. Only 25 are still lived in today, however, up until the 1980's, many more were resided in. It was at that time that the Jordanian government moved most of the Bedouins to more modest housing in the nearby town. Now, many of the people that used to live within Petra, come back to offer horse and camel rides, as well as to sell almost anything you could possibly want and many things that you don't.
