“Victoria Falls canoeing above the Falls on the upper Zambezi is the perfect activity for those who not only want to see the abundant bird and animal life but also want to experience the peace, tranquillity and beauty of the Zambezi River. The river is a kilometre wide and in places a bit more. It has an indescribable beauty with crystal clear waters and a myriad of islands and channels to explore.”
