Tanzania's natural wonders — towering volcanoes, paradisaical islands and sundry animal life — have inspired travelers from Ernest Hemingway (who hunted big game) to the rock band Toto (who rhymed “Serengeti” with “company”). Situated on Africa’s eastern coast, Tanzania consists of the mainland country, once called Tanganyika, and the exotic archipelago Zanzibar, located in the Indian Ocean 25 to 50 kilometers from the mainland.
