Shobak CastleThis is a castle south of Kerek and Dana. Hard to get to without a car or driver, but it is on a hill with spectacular views. Most of the castle is a pile of rubble but there are underground rooms to explore, including the staircase (through a metal door that should be open) that goes down 375 steps to the old wells. Take a torch, and note that at the bottom, you can climb up metal rungs to a hatch next to the road below the castle, then walk back up the road. 1 JD or included in the Jordan Pass.
Um er-RasasA largely unexcavated archeological site with Roman, Byzantine, & early Muslim ruins
The King's Highway trip to Petra starts from Madaba. It gives visitors a good opportunity to see people in the villages during their daily life, and the landscape is very nice: If you come in April you can see black irises on the way. It's a very nice stop to see the canyon of Wadi Mujeb with a 950-meter depth. Crossing this canyon you get to Karak and do a visit to the castle. After Karak toward Tafila you can do a stop to see the mountains of Dana and then after Tafila anther castle named Shaoubak. Then you get to Petra. This is a nice trip and more worthwhile to do than the desert highway.
