The Victoria Falls National Park is all about the Falls and they are truly magnificent. I have wanted to visit Victoria Falls for a long time and I expected it to be wonderful. While these two things are often a sure setup for disappointment, this was not the case. The Falls still exceeded my expectations. We visited on a beautiful, sunny day in mid-February. The Falls were still close to peak flow, so the sound, the view and the mist were all magnificent. Our guide, who had visited many times, of course, said that the rainbows were the nicest she had ever seen. Wow!
Do wear a poncho or expect to get wet. Personally, I opted for wet, just making sure that my camera was well-protected. It was part of the experience. I live about 3 hours from Niagara Falls on the Canadian side (& used to live closer) and have been there many times. Victoria Falls simply blew Niagara away. It wasn't even close. Sorry Niagara. The other nice thing about Victoria Falls is that it is all natural - no touristy things and no hydro-electric plant to drain water flow.
We did have some concerns about visiting Zimbabwe but we found that the Victoria Falls area, at least, was very safe and inviting to tourists.
