Wadi Musa
At the age of 18, Meir and his girlfriend managed to reach Petra at night, after three days of hiking, crossing Wadi Musa, climbing Mount Hor and bypassing an unpassable waterfall: they apparently slipped into the ancient city unnoticed, under the cover of darkness, before exploring the Nabatean vestiges. This feat made them legendary figures amongst the Israeli youth of the time, for whom Petra had represented an impenetrable citadel. "We had only a compass and a map on a small scale, but that was definitely enough to find our way to Petra," Har-Zion recalled.
