Madallah's Desert Moon Camp was the most fun thing to visit in Jordan. The jeep tour was excellent and contains everything (and more!) one could possibly do in a desert.... and that's definitely a pretty extensive list, just ask the guide especially if he's named Walid! From climbing to hop-skipping (or sand-dune jumping, as you wish), it's all in the game. Moreover the food is excellent and the same goes for the atmosphere.
We had a blast, thanks to Madallah for giving us one of our best experiences in Jordan. And Walid's an absolute legend!
Biggest surprise of all: the toilet can actually be flushed :-)
