Only a quarter of the Sahara Desert is sandy.

When we think of the Sahara Desert, an image of endless sand dunes stretching as far as the eye can see often comes to mind. However, contrary to popular belief, only a quarter of the Sahara Desert is actually covered in sand.

The Sahara, which is the largest hot desert in the world, spans a vast area of approximately 9.2 million square kilometers. Within this enormous expanse, only about 25% consists of the traditional rolling sand dunes that we typically associate with deserts. The rest of the desert is a mixture of rocky plateaus, gravel plains, stony hamada, and occasional salt flats.

The misconception of the Sahara being entirely covered in sand may have originated from popular media and movies, which often depict the desert as an endless sea of dunes. However, the reality is far more diverse and intriguing.

The sandy portion of the Sahara is known as the “erg,” which refers to a vast area covered in wind-swept sand dunes. The most famous erg in the Sahara is the Erg Chebbi in Morocco, featuring majestic dunes that can reach heights of up to 150 meters. These impressive dunes attract countless adventurers and tourists seeking a thrilling desert experience.

Aside from the ergs, the Sahara is also home to other fascinating landscapes that vary from region to region. The desert is intersected by mountain ranges, such as the Atlas Mountains, which offer breathtaking views and a stark contrast to the surrounding arid scenery. Additionally, oases can be found scattered throughout the desert, providing a haven of life amidst the harsh conditions. These oases are characterized by lush palm groves and settlements that have flourished due to the presence of underground water sources.

Despite its predominantly arid nature, the Sahara Desert also boasts a surprising variety of flora and fauna. Numerous desert-adapted species call this vast desert home, including the iconic dromedary camels, Barbary sheep, desert hedgehogs, and various reptile and bird species. The unique adaptations of these organisms enable them to thrive in an environment considered inhospitable by many.

Overall, the Sahara Desert is an intriguing landscape of contrasts and surprises. Only a quarter of its immense area is sandy, with the rest comprising diverse terrain that is just as captivating. Exploring the Sahara offers awe-inspiring vistas, rare wildlife encounters, and a glimpse into the remarkable resilience of life in extreme conditions.
