The Victoria Falls are possibly the most impressive to be found anywhere in the world. This legendary waterfall is among the biggest, and most awe-inspiring, on the planet. The Zambezi River is more than 1.25 miles (2 kilometers) wide when it cascades over the lip of a large basalt plateau and plunges as much as 354 feet (108 meters). The flow has been slicing slowly through this plateau for some two million years. During this time the river has slowly retreated and the remnants of earlier, ancient falls can be seen in the gorges downstream from the current cataract. The falls generate mists that can be spotted from more than a dozen miles (20 kilometers) away. Famed Scottish explorer David Livingstone dubbed this waterfall Victoria Falls; its older, Kololo name, Mosi-oa-Tunya, means ``the smoke that thunders.” The mists also sustain a rain forest-like ecosystem adjacent to the falls and on the opposite cliff that faces them like a dried-up mirror image, thick with mahogany, fig, palm, and other species of vegetation. The national border between Zambia and Zimbabwe lies midstream, and national parks of both nations exist on either side of the Zambezi. The gorges and cliffs below the falls in these parks are prime territory for raptors, including falcons and black eagles. Stone artifacts from the hominin Homo habilis have been identified near the falls and show that early humans may have lived here two million years ago. More “modern” tools also evidence far more recent—50,000 years ago—Middle Stone Age settlements. The Falls can be experienced from either the Zimbabwe side or the Zambian side and visitors can walk across the Bridge that spans the falls to briefly visit the other country. In addition to the natural attractions of the Falls offers high adrenaline activities such as Bungee Jumping, White Water Rafting and Microlight flights. Fixed wing and helicopter sightseeing is also available.
