The Victoria Falls is a waterfall situated in southern Africa between the countries of Zambia and Zimbabwe. From September to December, due to low water levels, it is possible to swim at the edge of the falls in a naturally formed safe pool, accessed via Livingstone Island.
From Virgin Media : “Life on the edge swim; ... a small jump (what felt like the leap of death) lands you in a small rock pool at the edge of the Falls. As you stand this close to such raw, natural beauty, you can barely hear yourself screaming above the sound of the water rushing down while adrenalin pumps through your body turning it into a shaking, excitable mess. You realise why the not-eating-before-swimming rule has always stuck".
