Victoria Falls is really a totally spectacular thing to visit and you’re right to consider it. Few things come close to the scale of the falls and the surrounding area.
Practically, it’s not a cheap or easy thing to do. There are only two airlines that fly to Victoria Falls Airport (VFA) and Livingstone and they fly in the middle of the day, once a day, either way. Flights start at around R2 000 per person one way, so you can see quickly that it’s a pricey addition to a South African trip.
