At 947,300 km2,Tanzania is the world's 31st-largest country. Compared to other African countries, it is slightly smaller than Egypt and comparable in size to Nigeria. It lies mostly between latitudes 1o and 12oS, and longitudes 29o and 41oE.
Tanzania is mountainous in the northeast, where Mount Kilimanjaro, Africa's highest peak, is situated. To the north and west are the Great Lakes of respectively Lake Victoria (Africa's largest lake) and Lake Tanganyika (the continent's deepest lake, known for its unique species of fish)-and to the southwest lies Lake Malawi whose elongated depression forms most of the country's border with Malawi. Central Tanzania comprises a large plateau, with plains and arable land. The eastern shore is hot and humid, with the island of Zanzibar lying just offshore.
Tanzania contains many large and ecologically significant wildlife parks, including the famous Ngorongoro Crater, Serengeti National Park in the north, and Selous Game Reserve and Mikumi National Park in the south. Gombe National Park in the west is known as the site of Dr. Jane Goodall's studies of chimpanzee behaviour.
The government of Tanzania through its department of tourism has embarked on a campaign to promote the Kalambo water falls in the southwestern region of Rukwa as one of Tanzania's main tourist destinations. The Kalambo Falls are the second highest in Africa and are located near the southern tip of Lake Tanganyika. The Menai Bay Conservation Area is Zanzibar's largest marine protected area.
