The Devil's Pool, the most dangerous natural swimming pool of the world
One of the most thrilling experiences – not only at the falls but in all of Africa – is the hair-raising journey to Livingstone Island. Here you will bathe in Devil's Pool – nature’s ultimate infinity pool, set directly on the edge of the Victoria Falls. You can leap into the pool and then poke your head over the edge to get an extraordinary view of the 100m drop. Here also you'll see the plaque marking the spot where David Livingstone first sighted the falls.
You can only visit Livingstone Island as part of a tour, and swimming in Devil's Pool is only possible during the drier months, usually from the middle of August to mid January. Five trips depart daily by boat to Livingstone Island, from where you'll swim to Devil's Pools. When the water is low around October and November, you’re able to access it via walking across, but a guide is compulsory. Note that access to the island is closed from around March to May when the water levels are too high.
