Victoria Falls
Zambia / Zimbabwe
The mist hits you 500 metres before you see the water. Then the ground shakes, and you understand why local people call it Mosi-oa-Tunya — the smoke that thunders. The falls are a kilometre wide and drop 108 metres into a narrow gorge, and in peak flood season the spray soaks you completely before you reach the first viewpoint. It is louder than you expect and wetter than you dress for.
