Adrar is a classic getaway to a magnificent caravan odyssey to the rambling dunes of the Sahara Desert. However, this small town doesn't have the grandeur that Constantine has but it has every reason to be proud of its old-fashioned historic monuments, ancient villages and rich landscape (some credit is also due to the presence of the fouggara or the underground water channels), ideal for the luxuriant growth of all types of cash crops.
One of the magnets of Adrar is the bizarre ring of rock that surrounds the massif of Adrar, which measures about 18 meters. No one, not even the most intelligent scholars, have so far been able to give a plausible explanation for the phenomenon of the circle of rock that lies in the expanse of the desert, neither about their origin nor about their purpose.
Another site worth visiting is the Place des Martyrs where the stunning Islamic mosque is nestled. To date, this remains one of the most striking architectural wonders built in Algeria as it has a unique red mud portico, adorned with wooden spikes which make a great entrance to the main square of the mosque.
To those who wish to navigate the outskirts of the town, there are the Tamentit and Sid Ahmed Timmi oases located some 12 kilometers north of Adrar. Here visitors can have all the time in the world to explore the landscape, inhabited by rare animals and plants such as sand cats, fennecs, hedgehogs and gazelles.
If they have still time to mingle with the locals in the Tamentit oases, they might as well witness the performance of the odd religious ritual of ziaretes (similar to the roquia), believed to relieve a soul from a demonic possession. Occasionally, the locals also visit the mosques where the marabouts (important spiritual leaders) are buried.
