Around 16h they will bring your camels. You will ride the camel and a porter, a kid maybe, will take the reins of the camel. In some cases the guide will sit behind you, an option I do not recommend. Before starting the camel tour, make sure each of you has its own camel. Do not share it.
The camel ride through the desert takes around three hours. During the camel ride you will see many wild animals: foxes, antelopes, cows, donkeys, camels, vultures, eagles, and many others.
