Without any human influence, nature has created extraordinary wonders - from majestic mountains and bubbling volcanoes to amazing plants and animals. These wonders are found across all the continents and oceans of this planet. In a tour of the seven greatest wonders of Africa, we'll encounter the Sahara, with its vast "seas of sand." We'll also find the world's longest river, the Nile. Many of Africa's most amazing wonders are animals. For instance, every year, millions of zebras and antelopes migrate across the Serengeti Plain in Kenya and Tanzania. The Virunga Mountains of central Africa provide a home for rare mountain gorillas. What other natural wonders does Africa hold? To find out, we'll explore magical islands, a snowcapped mountain, and a gigantic waterfall in fascinating detail.
