It would take 6 days of hiking from Petra to Wadi Rum. Anna-Sophie and I hiked part of the trek for one day. We started in an area where heavy fighting took place between Israel and Jordan in 1967. A cemetery of fallen soldiers was speaking of this
We hiked down into a wadi with hardly any path visible. The uneven ground was scattered with many rocks and boulders and required utter attention. Our Bedouine guide Yusuf was looking for a dry stick for me to use as a staff. It helped. He could not speak English, but pointed to many interesting sites and plants.
Farther down the valley, we passed some places with water still in the creek.
