Tanzania is where most people picture a safari, and for good reason. The northern circuit strings together the Serengeti, the Ngorongoro Crater, Tarangire and Lake Manyara within a few hours of each other — the Great Migration’s Mara River crossings from July to October, and half a million wildebeest calves born on the southern plains each February. Push west or south and the crowds vanish: chimpanzees in Mahale, buffalo herds in Katavi, and Ruaha’s baobab country. Offshore, Zanzibar turns a safari into a full holiday. Our Tanzania expeditions range from focused northern-circuit trips to multi-park journeys ending on the Indian Ocean.
