The dunes’ colors transform throughout the day, shifting from soft pinks to brilliant golds and deep oranges, particularly during sunrise and sunset when the interplay of light and shadow creates an otherworldly spectacle. This constant evolution of color and shape, sculpted by the desert winds, makes every visit to Erg Chebbi a unique experience. The fine, orange-colored sand that characterizes these dunes is believed to have been formed over millennia through the accumulation of wind-blown particles from the ancient Sahara.
Beyond its stunning natural beauty, Erg Chebbi holds significant cultural importance as the traditional homeland of several Berber tribes who have lived in harmony with this challenging environment for generations. The area around the dunes is dotted with small settlements, including the village of Merzouga at its western edge, where traditional desert life continues alongside modern desert tourism.
The dunes also host a diverse ecosystem adapted to the extreme desert conditions. Despite the harsh environment, various species of birds, reptiles, and small mammals make their home here, and after rare rain showers, the desert briefly blooms with unexpected patches of vegetation, creating a stunning contrast against the golden sands.
