Ruacana Falls
At one time, Ruacana Falls was a guaranteed wonder, though all that changed, thanks to Angola’s Calueque Dam, 20km upstream, and NamPower’s Ruacana power plant. On the rare occasion when there’s a surfeit of water, Ruacana returns to its former glory. In wetter years, it’s no exaggeration to say it rivals Victoria Falls – if you hear that it’s flowing, you certainly won’t regret a trip to see it (and it may be the closest you ever get to Angola).
