2. The Vast Expanse: How Big is the Sahara Desert?

The Sahara covers an astonishing 9.2 million square kilometers, stretching across much of North Africa. This makes it almost as large as the United States!

3. The Origin of ‘Sahara’: What’s in a Name?

The name ‘Sahara’ is derived from the Arabic word ‘Sahra,’ meaning ‘desert’. This tautological name emphasizes its defining aridness.

4. Saharan Sand Dunes: Nature’s Skyscrapers

The dunes of the Sahara, known as ergs, can reach impressive heights of up to 180 meters — nearly half as tall as the Empire State Building!

5. Life in the Sahara Desert: Adaptation and Survival

Despite its harsh conditions, the Sahara is home to several resilient communities. Nomadic tribes such as the Tuareg and the Berbers traverse these arid lands, adapting to one of Earth’s most extreme environments.

6. Temperature Extremes: Surviving the Sahara’s Heat

During summer, temperatures in the Sahara can soar to between 38-46°C (100-115°F), creating an almost otherworldly landscape of heat and sand.

7. Prehistoric Sahara: A Haven for Dinosaur Fossils

The Sahara was once a much wetter place, where numerous dinosaur fossils have been discovered, providing a window into its prehistoric past.

9. Emi Koussi Volcano: The Sahara’s Tallest Peak

The highest point in the Sahara is the Emi Koussi volcano in Chad, which towers at 3,415 meters above sea level.

11. Water in the Desert: Exploring the Sahara’s Lakes and Oases

Contrary to its dry reputation, the Sahara boasts over 20 lakes and numerous oases, which serve as vital water sources and havens for wildlife and humans alike. Additionally, the ingenious Khettara underground irrigation systems, a traditional method developed centuries ago, play a crucial role in distributing water in this arid region. These subterranean channels effectively bring groundwater to the surface, supporting agriculture and sustaining life even in the harshest environments. The integration of Khettara systems highlights the adaptability and ingenuity of desert dwellers in managing scarce water resources.

Visitors can engage in a variety of things to do in the Sahara Desert, from camel trekking and sandboarding to exploring ancient ruins and star-gazing under one of the clearest night skies in the world.
