Welcome to Mars. Or at least, Mars as the makers of the movie Red Planet would have you believe. Wadi Rum, in the far south of Jordan between Petra and Aqaba, feels like another planet. A desert spanning kilometres, with mammoth mountains every shade of red, orange and yellow towering up into the electric blue sky. Follow in T.E. Lawrence’s footsteps by day and explore by jeep, camel or rock climb, and take shelter from the desert winds when you can. By night, sleep under the stars or cosy up in a local Bedouin tent. Your time in the Valley of the Moon will be out of this world.
