This is not so extreme as it is made out to be. The water is just waist deep during low flooding season, and the edge, is blocked by a rock edge. So the flow is not strong, and wont take you over the edge.
This is free, as you can jump into the river from any of the connecting resorts on the riverbank.

The extreme part is this..the river is the border of Zimbabwe and Zambia, with gorilla fighters on the Zambia side. if this isnt extreme enough...the river is full of hippos, which is the major cause of death for the local population, and if the hippo doesnt get you....the crockodiles surely will!!!

The beautifull part of the place is watching the waterfall which causes so much spray, it creates a rain forest close to the "pit" and the pit/pond is filled with lots of rainbows, as the sun reflects on the water.

Good place to visit and very cheap!
