Swimming in Devil's Pool at the lip of Victoria Falls is considered safe only when done through a licensed tour operator during the "Low Water" season, which typically runs from mid-August to mid-January. During this window, the water levels of the Zambezi River drop significantly, revealing a natural rock barrier at the edge that creates a calm eddy where you can safely sit right at the precipice. In 2026, the guides from Tongabezi Lodge (the only official operators) are highly trained to monitor the currents and will cancel tours immediately if the water rises even slightly above the safety threshold. However, it is extremely dangerous and often fatal to attempt swimming there during the "High Water" season (February to July) or without a professional guide. The current during high water is powerful enough to sweep a human over the 108-meter drop in seconds. For those who follow the rules, the safety record is excellent, with no reported fatalities among guided tour participants in over 20 years. The primary "risk" is the slippery walk across the rocks to reach the pool and the small "nibbling" fish that might tickle your feet, rather than the waterfall itself, provided you stay behind the guide's designated safety line.
