In peak flood season (February to May), the spray thrown up by the plunging water can be seen from 30 miles/48 kilometers away. This magnificent spectacle gives the falls its indigenous name — Mosi-oa-Tunya, or "The Smoke That Thunders". On the Zimbabwean side, a path winds its way along the edge of the gorge. Viewpoints offer breathtaking panoramas of the plummeting water and the rainbows that hang suspended above the chasm. The sound is deafening and the spray soaks to the skin - but the spectacle is one that can never be forgotten.
