Tanzania has a varied geography, including deep and large freshwater and salt lakes, many national parks, and Africa's highest point, Mount Kilimanjaro (5,895 m or 19,341 ft)
Northeast Tanzania is mountainous and includes Mount Meru, an active volcano, Mount Kilimanjaro, a dormant volcano, and the Usambara and Pare mountain ranges. Kilimanjaro attracts thousands of tourists each year.
West of those mountains is the Gregory Rift, which is the eastern arm of the Great Rift Valley. On the floor of the rift are a number of large salt lakes, including Natron in the north, Manyara in the south, and Eyasi in the southwest. The rift also encompasses the Crater Highlands, which includes the Ngorongoro Conservation Area and the Ngorongoro Crater. Just to the south of Lake Natron is Ol Doinyo Lengai (3,188 m or 10,459 ft), the world’s only active volcano to produce natrocarbonatite lava. To the west of the Crater Highlands lies Serengeti National Park, which is famous for its lions, leopards, elephants, rhinoceroses, and buffalo plus the annual migration of millions of white bearded wildebeest. Just to the southeast of the park is Olduvai Gorge, where many of the oldest hominid fossils and artifacts have been found.
Further northwest is Lake Victoria on the Kenya–Uganda–Tanzania border. This is the largest lake in Africa by surface area and is traditionally named as the source of the Nile River. Lake Victoria covers 69,490 sq km (26,832 sq miles), which is Africa’s largest lake and 49% of it lies in Tanzania. Southwest of this, separating Tanzania from the Democratic Republic of the Congo, is Lake Tanganyika . This lake is estimated to be the deepest lake in Africa and second deepest lake in the world after Lake Baikal in Siberia, with maximum depths of 1,470m (4,821ft), and is 673km (420 miles) long and averages 50km (31 miles) across; 41% of its area lies in Tanzania. The western portion of the country between Lakes Victoria, Tanganyika, and Malawi consists of flat land that has been categorised by the World Wildlife Fund as part of the Central Zambezian Miombo woodlands ecoregion. Just upstream from the Kalambo Falls, there is one of the most important archaeological sites in Africa.
The Tanzanian mainland is divided into several clearly defined regions: the coastal plains, which vary in width from 16 to 64km (10 to 39 miles) and have lush, tropical vegetation; the Masai Steppe in the north, 213 to 1,067m (698 to 3,500ft) above sea level.
The centre of Tanzania is a large plateau, which is part of the East African Plateau. The southern half of this plateau is grassland within the Eastern Miombo woodlands ecoregion, the majority of which is covered by the huge Selous National Park. Further north the plateau is arable land and includes the national capital, Dodoma.
The eastern coast contains Tanzania’s largest city and former capital, Dar es Salaam. Just north of this city lies the Zanzibar Archipelago, a semi-autonomous territory of Tanzania which is famous for its spices.
The coast is home to areas of East African mangroves, mangrove swamps that are an important habitat for wildlife on land and in the water.
