Taking a dip at the bottom of a waterfall can be fun. Doing the same at the top of a waterfall is usually ill-advised. And if you’re taking a dip at the top of the largest sheet of falling water in the world, then you are visiting Devil’s Pool at Victoria Falls on the border between Zambia and Zimbabwe. Although 38,430 cubic feet of water slip over the 355-foot drop per second here, plenty are willing to risk involuntarily going with the flow to visit this unique infinity pool. The naturally formed pool is perched atop the Zambian side of the falls, and if you want to take the plunge you have until early next month. The pool is open between September and early January each year, closing when the rainy season picks up and the water gets a little too swift. Check out this sky-high swimming hole below.

Since the early 2000s, tourists overwhelmingly chose to stay on the Zambian side of the falls, a trend unlikely to change until the political situation in Zimbabwe improves. Image by Sarah Depper

Day trips to the falls require a permit, which will set you back $20 to $50. Image by Sarah Depper

For some visitors, like the flipping daredevil above, swimming here just isn’t harrowing enough. Image by Devil’s Pool Victoria Falls

Upwards of 100,000 tourists visit Victoria Falls annually, a fact that worries conservationists who fear commercialism will hurt the World Heritage Site. Image by Devil’s Pool Victoria Falls

Victoria Falls from the air is pretty overwhelming. It’s little wonder visitors want to immerse themselves in this. Image by Victoria Falls – Swimming in Devil’s Pool
