The best time to visit Zimbabwe is from May to September. At this time Victoria Falls is most impressive and wildlife viewing is excellent as animals congregate around the rivers and waterholes. This is especially true in Hwange where the artificially pumped waterholes attract big herds of elephant.

Best Time To Go by Major Park
Most parks offer year-round wildlife viewing, but they are at their best during the Dry season when wildlife is easier to spot. Hwange is best visited in September-October when it is a magnet for big elephant herds. Photo opportunities of Victoria Falls are best between May and December. The rainy season is a beautiful time in Zimbabwe and excellent for birdwatching, but the road conditions can be a problem, especially the 4x4 tracks in Mana Pools.
