Climbing old Bedouin hunting routes in Wadi Rum
If you like the desert, Wadi Rum is a fantastic place to relax for a few days. They have amazingly comfortable tents onsite (4$ a night), a great little rock climbing community, and a little general store that cooks group style breakfast and dinners.
If you want some adventure, I suggest going for a climb. You can follow markers left by Bedouin hunters and climb routes up into these rocks for days. The views are unearthly.
