The United Republic of Tanzania (the largest country in East Africa, including the islands of Zanzibar and Pemba) came into existence in 1964, three years after the initial independence from Britain by Tanzania. Although it shares many characteristics with its northern neighbour (especially the Swahili culture and language), it has developed along more socialist lines than has Kenya. However, Tanzania's game parks are - if anything - even better known than those of Kenya. The Serengeti National Park and neighbouring Ngorongoro Conservation Area is truly world renowned, as is Africa's highest peak Mount Kilimanjaro. All of these highlights are within easy reach of Nairobi, attracting many tourists and earning Tanzania much needed foreign exchange. Tarangire National Park and Lake Manyara National Park are in close proximity to Arusha and can be easily combined with visits to the Serengeti National Park and neighbouring Ngorongoro Conservation Area. The two lakes dominate Tanzania are Lake Victoria, the world's second largest freshwater lake, and Lake Tanganyika, the longest fresh water lake in the world and the second deepest. For those wanting to relax after their safari or trek Zanzibar is Tanzania's idyllic island getaway. It has a colourful history, spice plantations and beautiful beaches.
