The Adrar's mountains are from the primary era against the precambrian Tiris Zemmour. Near Atar, you can find stromatolites. In the North, you can find Choum with the train that comes from Nouadhibou and goes to Zouerate. East of Atar, through Amojjar Pass, is the difficult way to Chinguetti, Ouadane and the astonishing Richat Structure.^[2]

Atar has a hot desert climate (Köppen climate classification BWh) typical of the Sahara Desert, south of the tropic of Cancer. The weather is usually very hot, very sunny and very dry but it can be overcast sometimes. The annual average temperature is close to 30 °C (86 °F), meaning that excessive heat persists year-round. The annual mean rainfall amount is very low, averaging no more than 35 mm and it mainly falls in August and in September while the sunshine duration is high, at over 3,540 h of bright sunshine yearly.

Today, the Atar is best known to outsiders as an entryway for tourists to visit the ruins of the ancient Moorish cities of Ouadane and Chinguetti. It was a key stop in the world's longest off-road race, the Paris Dakar Rally, held every January.

The "samaras" (from Arab smela : sole) are made in Atar and well known in Mauritania. It's a leather sole with straps.
