Then in the horizon appear the "sand sea" of Erg MURZUG! We hug the coast of the dunes, that seem to be eiscream of vaniglia, coffee, cream, sillabub. We stop at a point of view: to me is the top of the top of this travel. I'm happy, thanks to the guide Barka, I reach my dream to see the Erg Murzuq, a round area of 400 km only of dunes, the most barren place of the earth.
