Nubian Desert

Northern Sudan, Sudan

---

The Nubian Desert, in northern Sudan between the Nile River valley to the west and the Red Sea to the east, forms a vast, rugged sandstone plateau covering around 400,000 square kilometers, characterized by rocky terrain, scattered dunes, and numerous dry wadis that fade before reaching the Nile.

Bounded by Egypt to the north and extending southward toward the Nile's confluence, it receives minimal rainfall under 5 inches annually, supporting sparse vegetation and nomadic pastoralism amid dramatic Red Sea Hills rising to peaks like Jabal Erba at over 7,000 feet. 

This arid expanse, part of the eastern Sahara, holds geological significance with ancient rock formations and serves as a harsh barrier linking Sudan's diverse landscapes.
