Nothing will prepare you for the sheer drama of Victoria Falls holidays. For giddying views of its thunderous torrents, take a dunk in the nail-biting Devil’s Pool at the tip of the falls, where vivid rainbows shoot through the spray and microlights circle from above with gawping passengers staring into the frothy depths. The fantastic thing about the falls - or Mosi-oa-Tunya (‘The Smoke That Thunders’) - is that it can be combined with other exceptional national parks - including Chobe, Etosha and Kruger - and tied into any number of itineraries across Botswana, Namibia, South Africa, Zambia and Zimbabwe.
