Yes, I can recommend this place: camping Bab Sahara run
by the Dutch – Justus and his wife is located on the outskirts of the town of Atar.
They have big tents and two stone rondavels – each for 4 persons. And they charge 7000 ougija /like 20euro/ per rondavel. There is only cold shover but the hosts are very friendly, very knowlegeable and helpful. Local cook will prepare for you the rice with fish and salad for 600 ougija.
Atar is very tiny – the capital of province has no high buidings,
only one internet cafe and 4-rooms museum… Atar has inexpensive charter flights from France by Point Afrique /from 220 euro each way – what a deal!/ and is used mostly as a base for the expeditions to the oases in the desert. We will start our tomorrow -Insz Allach!
