Tanzania is mountainous and densely forested in the north-east, where Mount Kilimanjaro is located. Three of Africa’s Great Lakes are partly within Tanzania. To the north and west lie Lake Victoria, Africa’s largest lake, and Lake Tanganyika, the continent’s deepest lake, known for its unique species of fish. To the south lies Lake Malawi. The eastern shore is hot and humid, with the Zanzibar Archipelago just offshore.
