Fodor's Expert Review Erg Chebbi
In most cases your hotel is your best bet for an organized tour of Erg Chebbi. Every auberge near the dunes is there because it's a prime jumping-off point for a sunrise or sunset journey, either on foot or by camel. Most auberges have their own permanent bivouac in the dunes, often not far from others but generally fairly well concealed—which lets you pretend no one else is around even if they are. Most bivouac areas are organized into series of small tents for couples and larger groups, so you don't have to share with everyone. If you want to be utterly private, make sure your auberge doesn't share a tented site with any other, or ask to camp in the dunes on your own.
