Nature & Desert

Without the Nile, there would be no Egypt. The longest river in the world (6,650 km, of which 1,550 km are in Egypt) created the fertile alluvial land through its annual floods, on which the pharaonic civilization emerged. 97% of Egypt's population live on the narrow 4% of the land that the Nile irrigates — a green strip through the desert.

The Aswan High Dam (completed in 1970) ended the annual floods and enabled year-round agriculture. The downside: the nutrient-rich Nile silt now settles in Lake Nasser, coastal erosion in the Nile Delta has increased, and the ecological balance has been altered. The Nile remains Egypt's greatest geopolitical challenge — the dispute with Ethiopia over the GERD (Grand Ethiopian Renaissance Dam) is one of the world's most pressing water conflicts.

The Red Sea is one of the most species-rich marine areas in the world — and at the same time one of the most threatened. Over 220 coral species and 1,200 fish species (10% of which are endemic, occurring only here) live in the reefs. The high biodiversity is due to the warm, nutrient-poor water, the isolation (only a narrow connection to the Indian Ocean), and the geologically young coral reefs.

Threats: Climate change (coral bleaching), overfishing, coastal development (hotels directly on the reef), snorkeling damage (tourists stepping on corals), and plastic waste. Some reefs have been significantly damaged in the last 20 years. Responsible diving and snorkeling (do not touch corals, do not litter in the sea, reef-friendly sunscreen) is mandatory.

Egypt has not one, but several fascinating desert landscapes:

• White Desert (Sahara el-Beida): Surreal limestone formations, eroded into shapes resembling mushrooms, animals, and humans. In the moonlight, they look like a snowy landscape. Camping under the starry sky is an unforgettable experience. Bookable from Cairo as a 2-day tour (80–120 € per person).
• Black Desert: Volcanic basalt hills that darken the desert — a dramatic contrast to the White Desert. Often visited on the same tour.
• Sinai Desert: Red granite mountains, deep canyons, Bedouin cultures. Quite different from the western Sahara — more rugged, mountainous, and colorful.
• Siwa Oasis: The most remote oasis in Egypt, near the Libyan border. Berber culture, hot springs, the Oracle Temple of Amun (where Alexander the Great was declared the son of the god). Salt lakes, date palms, absolute tranquility. From Cairo: 8–10 hours by bus or off-road vehicle.
