Zambian or Zimbabwean side
Two thirds of the actual falls lie within the Zambian territory, as does Livingstone Island, from where David Livingstone first famously set eyes on the falls. The water from Victoria Falls dives into a narrow gorge running parallel to the face of the falls, with the spray going high into the air, causing permanent rain, rainbows and the famous “smoke” which is visible from a distance, so, much of the time when you are viewing the falls, you are actually facing them. The gorge where the water exits is the limit on how far you can walk from either side. There is no crossing there. This limits your visibility from the Zambian side, as you can walk about only a quarter of the distance of the face of the falls. Although the view and the waterflow is still impressive, you simply cannot get a perspective on the full width of the falls from the Zambian side.
The walk down to below the falls is closed on the Zimbabwean side. You can only walk down on the Zambian side. The footbridge on the Zambian side gives a unique experience, with a permanent torrential rain from the wet season through to August. Travelers will have an assortment of visa charges involved in seeing both sides of the falls. The variables include your nationality, single or multiple entry, and whether you will stay longer than 24 hours. Flying to the Zambian side usually costs less than flying into the Zimbabwe side. Still, for less than US$100, you can do both sides.
