Eight neighbouring countries, Kilimanjaro at 5,895 m and the floor of Lake Tanganyika: Tanzania's physical frame
Background
The saltwater intrusion story elsewhere in today's country section turns on Tanzania's Indian Ocean coast, which is part of this frame.
The East African Community records that Tanzania borders eight countries: Kenya, Uganda, Rwanda, Burundi, the Democratic Republic of Congo across Lake Tanganyika, Zambia, Malawi and Mozambique.
The Indian Ocean lies to its east.
Mount Kilimanjaro is the highest point at 5,895 metres above sea level, and UNESCO's World Heritage listing calls it the highest point in Africa, rising 4,877 m above the surrounding plains.
The floor of Lake Tanganyika lies 358 metres below sea level, recorded as Africa's lowest point.
Tanzania has over 61,000 sq km of inland water, and ferries operate on Lake Victoria.
