The river Nile, over 800 Km in length with in Ethiopia and the longest river in Africa, holds part of its heart in Ethiopia from Lake Tana, the Blue Nile, known locally as Abay, flows for 800 Km within Ethiopia to meet the White Nile in Khartoum to form the great river. It has been said that the Blue Nile contributes up to 80% of the Nile's flow. Nowhere, is it more spectacular than where it thunders over the Tis Isat Falls literally "Smoking Water" - near Bahir Dar. Here millions of gallons of water cascade over the cliff face and into a gorge, creating spectacular rainbows, in one of the most awe-inspiring displays in Africa.
The Blue Nile falls can easily be reached from Bahir Dar and the scenic beauty of the Blue Nile Gorge, 225 Km from Addis Ababa, can be enjoyed as part of an excursion from the capital.
