I remember reading years ago about how, as you approach the Sahara Desert, the whole horizon is occupied by what seems to be a never-ending range of mountains which loom out of the ground in all their burnt amber glory. Ever since reading about them, I have dreamt about the dunes of orange sand that are tall enough to reach the sky and stars. I’ve imagined the long-limbed, lumbering camels that carry their masters for miles upon miles, their steady, swaying strides never faltering. For me, this encapsulated the ultimate adventure: the hardship of the intense sun and persistent sand, combined with the beauty of the inhospitable desert and the exhilaration of travelling high on the back of such a foreign four-legged animal. Finally, after years of impatiently flicking through photos and reading accounts of camel treks in the Sahara, it was my turn.
