Rainbow Over Victoria Falls, Zambezi River, Africa

In 1964, Northern Rhodesia became the independent state of Zambia. The following year, Rhodesia unilaterally declared independence. This was not recognized by Zambia, the United Kingdom or the vast majority of states and led to UN-mandated sanctions. In response to the emerging crisis, in 1966 Zambia restricted or stopped border crossings; it did not re-open the border completely until 1980. Guerilla warfare arose on the southern side of the Zambezi from 1972: the Rhodesian Bush War. Visitor numbers began to drop, particularly on the Rhodesian side. The war affected Zambia through military incursions, causing the latter to impose security measures including the stationing of soldiers to restrict access to the gorges and some parts of the falls.
Zimbabwe's internationally recognised independence in 1980 brought comparative peace, and the 1980s witnessed renewed levels of tourism and the development of the region as a centre for adventure sports. Activities that gained popularity in the area include whitewater rafting in the gorges, bungee jumping from the bridge, game fishing, horse riding, kayaking, and flights over the falls.
• Tourism in recent years
By the end of the 1990s almost 300,000 people were visiting the falls annually, and this was expected to rise to over a million in the next decade. Unlike the game parks, Victoria Falls has more Zimbabwean and Zambian visitors than international tourists; the attraction is accessible by bus and train, and is therefore comparatively inexpensive to reach.
