Check with your operator before booking, if this is a concern. The experience varies in intensity, depending on the amount of water flowing through the gorge. In the case of white water rafting, less tends to mean more!
Typically, winter - the drier season - sees the river raging around rocks and outcrops, and the waves generated tend to be higher relative to the water level than in summer.
Appropriate clothing for the experience is a baseball-style hat, swimming shorts, a T-shirt and old footwear that will stand a soaking. Operators joke that the river god, Nyaminyami, is keen on removing rafters' shoes when not well secured.
Under no circumstances should you take a camera, passport or any valuables with you - even spectacles should be left behind unless it is absolutely necessary to use them.
Helicopter transfers in and out of the gorge are available from both Zimbabwe and Zambia

River boarding is the latest adrenalin sport to hit Victoria Falls. It's like surfing the Zambezi. As the brochure says "swim the rapids and surf the waves, armed with nothing more than an over-sized bodyboard, wetsuit and flippers". Operators offer a day-long combination of rafting and river-boarding.
