Tanzania lies on the eastern coast of Africa, bordering the warm Indian Ocean. It is defined by the Great Rift Valley, which has created a landscape ranging from the snowy peak of Mount Kilimanjaro to the vast plains of the interior. The nation is a harmonious mosaic of over one hundred ethnic groups, with Swahili culture flourishing along the coast. In the archipelago of Zanzibar, travelers wander the historic alleys of Stone Town, while the mainland offers the challenge of climbing the Roof of Africa. The country is most famous for its unparalleled safari experiences. Visitors flock to the Serengeti National Park to witness the thundering Great Migration, or descend into the Ngorongoro Crater to see the Big Five in a volcanic caldera. You can find the pristine beaches of Pemba Island, the chimpanzee forests of Gombe Stream, and the vast waters of Lake Victoria.
