Atar is a town of 25,000 people (2013) in Saharan Mauritania. It is a great base for exploring the Adrar region, and tends to be slightly cheaper overall than Chinguetti. The Atar Mosque, one of the oldest mosques in the country, dates from 1674.

Atar is growing in importance due to its proximity to an airport and a regional hospital.

Atar has a hot desert climate 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 hr of bright sunshine yearly.

Map of Atar

• 20.506667-13.0430561 Atar International Airport (Mouakchott Airport ATR  ^IATA). Used to be served by a daily flight from Marseille, France but there are only small charter flights available due to the kidnappings in other parts of Mauritania.  

The Iron Ore Train typically departs from Nouadhibou sometime between 14:30 and 22:00, depending when the cargo is finished loading. There is only one train a day with passenger cars and tickets can be arranged in advance or bought at the Nouadhibou train station (Gare Voyageurs) for around 1,500 ouguiyas. Travel in the bucket wagons is free, just climb aboard, but it will be cold and dusty. The train stops at Choum where you can easily grab a ride to Atar in one of the many bush taxis or pickups which will meet the train for around 1,500-2,000 ouguiyas.

There is a paved and fast road which runs from Nouakchott to Atar served by a variety of minibuses (including one run by a kindly French ex-pat) and bush taxis. All of the rides going to Atar tend to leave Nouakchott from the Garage Atar at the end of town. Typical fare is around 4000 ouguiyas.

Atar is quite small and can easily be walked, although some auberges and resorts lie quite far out of town. Taxis are available and can usually be caught around the traffic circle in the centre of town, fares are around 100-300 ouguiyas depending on distance.

Atar has a few markets which may be of interest to the souvenir hunter and prices tend to be lower than Chinguetti, and bargaining is expected.

• 20.51707-13.052991 Musée Universitaire Atar, Rue Wilaya (next to BAMIS). 09:00-13:00, 16:00-18:00. Museum with displays on local culture. (updated Sep 2018)

• Galerie Artisanale Chez Picasso, Route vers Choum. Souvenir shop selling the usual Mauritanian and African items. (updated Sep 2018)
• La Boutique d'Adrar pour la Fabrication Traditionnelle et les Météorites, Rue Wilaya. Souvenir shop with a selection of meteorite rocks and other geological curiosities from the region. (updated Sep 2018)

• Restaurant Agadir. In the center of town, it serves typical Moroccan fare for around 600 ouguiyas a plate. 
• Restaurant De la Coin. A little harder to find, this hole-in-the-wall Senegalese restaurant dishes out plates at around 300 ouguiyas. 
• Auberge Bab Sahara. On the pricier end, try a home-cooked lunch (from 700 ouguiyas) or dinner (3,500 ouguiyas for a 3-course menu) 

The occasional beer can be found at Auberge Bab Sahara.

For its size, Atar contains a good number of auberges, hotels and resorts.

• The Auberge Bab Sahara (about a km outside of town on the road to Choum). Has rooms ranging from mattresses on one of two terraces to a number of traditional tents or stone huts. Plentiful bathroom and shower facilities (including hot water). The hospitality of the owners is genuine and they will gladly help arrange bush taxis or tours. Terrace/Tent spots start at 2,000 ouguiyas (1500 for students and cyclists) and 5,000 for huts.. 

• Elmejd Info (south of the NP petrol station). The only internet cafe in town. (updated Sep 2018)

Bush taxis (taxis brousses) or 4x4s to Choum, Chinguetti, or Nouakchott can be arranged in the Garage, the market or at most hotels.

Many of the oases and other natural sites in the region can be seen in day trips leaving from Atar. Ask around at your hotel/auberge to arrange bush taxis, 4x4s, or rent bikes. If your feeling adventurous wander into the market and you will doubtless get offers of obliging drivers ready to show you what they consider to be the most interesting sites.

Some of the notable sites in the region include oases (Terjit, Mhaireth), dunes (Valle Blanche, Amatlich), and old towns (Azougi, Chinguetti).
