I am told that the Falls are very different on the Zimbabwe Side from the Zambia side, and that to cross the border from Zambia is a must. We will be in Zambia the middle of April. Can anyone advise if this is true and what we need to do about visas to cross over. We are only in Zambia for a few days so want to make the most of our stay. I have heard that the falls can be quite impressive this time of year due to the rains.
