We flew from Johannesburg to Livingstone, Zambia, to get to Victoria Falls.  We stood in a line for over an hour to get a dual entry visa for Zambia.  We had to get from Zambia to Zimbabwe to get to the falls and we ended up walking our luggage across the border to a different bus.  Very strange.  We went on a walk at Victoria Falls and it's quite a sight.  They are 2 times taller than Niagara Falls with enough water going over to supply New York City for a year.  Don't know how accurate that is.  There were many references and a statue to David Livingstone, the European to "discover" the falls.  There was lots of water and mist being generated and lots of rainbows.  It's truly "the smoke that thunders".
We were lucky enough to take a helicopter ride over the falls and the rivers that feed them.  The gorge of the waterfall was much narrower than it appeared from the path on the other side.    Just a small crevice that opened up to let the water flow over it.  The Chobe and the Zambizi are the rivers that converge to form the falls.  This was a good time to see them because there was lots of water flowing.
We ended the day with a cruise on the Zambizi river and was several hippos, beautiful colors on the "smoke" over the falls and a pretty sunset.  A nice way to end the time at Victoria Falls.
