het heet de devil's pool en is geen zwembad
A famous feature is the naturally formed Devil's Pool, near the edge of the falls on Livingstone Island on the Zambian side. When the river flow is at a certain level, usually between September and December, a rock barrier forms an eddy with minimal current, allowing adventurous swimmers to splash around in relative safety a few feet from the point where the water cascades over the falls. Occasional deaths have been reported when people have slipped over the rock barrier.
