Ouadane had its glory days when the slave and gold caravans between Morocco and Ghana made their last stop here. That was long ago. Now there is just a quiet oasis town left, a UNESCO World Heritage Site slowly crumbling in the desert.
The wadi and date palm groves are still lush below the cliff, and east of the modern town the ruins of the Ksar el Klali fort and the old mosque look out over the Adrar plateau. There is also a small Museum of Ouadane and a library of ancient manuscripts you can visit.
Ouadane is about 120 kilometres from Chinguetti and double that from Atar. Rides are irregular. If you are driving yourself, you will need a 4WD, and a guide is advisable — especially for the route between Chinguetti and Ouadane.
