The hike between Dana and Feynan is best undertaken downhill, unless you are particularly fit. It descends (or ascends!) several hundred metres from the Jordanian plateau at the village of Dana, down to the Great Rift Valley at Feynan, which is close to sea-level. You can do this with or without a guide; the path is fairly obvious, but a guide adds more than just knowledge of the route: they are all local and can tell you about the wildlife and fauna of the wadi system, as well as helping you spot them. There are also the remains of ancient copper mines in the walls of the wadi that make for an interesting side-trip for the fit. The walk takes 5-7 hours and is a superb way to arrive at Feynan Eco-lodge.
