Views of the Victoria Falls.  The Victoria Falls are one of the world's most spectacular plunges. The 2km(1.2mi)-wide Zambezi River drops more than 100m (328ft) into a steeply-walled gorge. The Zambian side of Victoria Falls has long played second fiddle to its better-known Zimbabwean counterpart, but trouble next door means Livingstone is positively booming. For close-up views of the Eastern Cataract, nothing beats the hair-raising (and hair-wetting) walk across the footbridge, through swirling clouds of mist, to a sheer buttress called the Knife Edge. If the water is low and the wind favourable, you'll be treated to a magnificent view of the falls and the yawning abyss below the Zambezi Bridge. Adrenaline junkies can indulge in white-water rafting, abseiling, river-boating, jet-boating, bungee jumping and a host of airborne activities. At certain times of year it is even possible to visit Livingstone Island and swim at the very edge of the Falls, though sadly it's no longer free. Don't get so caught up with activities that you miss one of the most spectacular waterfalls in the world. The Mosi-oa-Tunya/Victoria Falls is the largest curtain of falling water in the world; it is 1.708 m wide and with up to 500 million litres per minute descending at 61 m (Devil’s Cataract), 83 m (Main Falls), 99 m (Rainbow Falls), 98 m (Eastern Cataract). Eight spectacular gorges of igneous origin (i.e. comprising basalts) and several islands in the core zone serve as breeding sites for four endangered and migratory bird species, such as the Taita Falcon and Black Eagle. The riverine 'rainforest' within the waterfall splash zone is a fragile ecosystem of discontinuous forest on sandy alluvium, dependent upon maintenance of abundant water and high humidity resulting from the spray plume of about 500 m (at maximum height) that can be seen from a distance of 50 km and 30 km from Bulawayo and Lusaka roads respectively. A direct frontage viewing of the falls is possible from both Zambia and Zimbabwe.
