This river is mythical and majestic. It has its source somewhere in the African jungle and ends its course in the Mediterranean Sea in Egypt. The source of the Nile is still a mystery. It is indeed very complicated to find the starting point

The Nile flows through Ethiopia, Sudan, Egypt, Rwanda, Tanzania, Burundi, Kenya, Eritrea, and the Democratic Republic of Congo.
