Tanzania is an East African country known for its vast wilderness areas. They include the plains of Serengeti National Park, a safari mecca populated by the “big five” game (elephant, lion, leopard, buffalo, rhino), and Kilimanjaro National Park, home to Africa’s highest mountain. Offshore lie the tropical islands of Zanzibar, with Arabic influences, and Mafia, with a marine park home to whale sharks and coral reefs. Dar es Salaam, a major city and commercial port on Tanzania’s Indian Ocean coast, grew from a fishing village. Arusha is a city in Tanzania located at the base of volcanic Mt. Meru. It's a gateway to safari destinations and to Africa's highest peak, 5,895m Mt. Kilimanjaro, lying some 100 kilometers northeast. To the west lies Serengeti National Park, home to wildlife including lions, rhinoceros, giraffes and leopards. Annual migrations feature huge herds of wildebeests crossing its plains.
