Erg Chebbi, located in southeastern Morocco, is recognized as one of the natural wonders of the Sahara Desert, just outside of the town of Merzouga. The dunes stretch over twenty-eight kilometers long from north to south, with heights reaching 150 meters. The vast expanse of golden-orange sand creates a colorful sight that is ever-changing on a daily basis; the mesmerizing forms of the dunes are best observed during sunrise and sunset.
