Victoria Falls
Victoria Falls is one of the Seven Natural Wonders of the World. It is 1.7 km wide and 108 m high. Victoria Falls is located on the border between Zambia and Zimbabwe. The Zambezi River, which originates in northern Zambia, serves as the fall’s water source. Victoria Falls was discovered by the Scottish explorer Dr. David Livingstone in 1855. He named the falls after Queen Victoria. The locals called the falls Mosi-oa-Tunya meaning “smoke that thunders.” Long before you even see the waterfalls you can hear the roaring of the water! The falls were formed by a deep rift in the rock that lies directly across the path of the Zambezi River. The rift was caused by movement of the earth about 150 million years ago.
The months of June and July are probably the best time to view the falls. The water levels are still high enough to showcase the splendor of the falls, but the amount of water is less creating less spray and more visibility of the falls.
