Blue Nile River
The Blue Nile originates at Lake Tana in Ethiopia (where it is called the Abay River). The river flows generally south before entering a canyon about 400 km (250 mi) long, about 30 km (19 mi) from Lake Tana, which is a tremendous obstacle for travel and communication between north and south Ethiopia. The canyon was first referred to as the “Grand Canyon” in 1968 by a British team that accomplished the first descent of the river from Lake Tana to the end of the canyon; subsequent river rafting parties called it the “Grand Canyon of the Nile”. The Blue Nile Falls (Amharic: Tis Abay, literally “great smoke”), one of Ethiopia’s biggest tourist attractions, is located at the start of the canyon.
