King's Highway is a region in Jordan. The name comes from the ancient trade route that ran right through it.
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.
On the King's Highway there are few places to eat. The stop at Karak to visit the castle will give you time to have lunch within some restaurants near the site.
You can stay overnight in Karak or at Dana Reserve.
