The Great Migration in Tanzania is one of the most incredible wildlife events in the world. It involves over 1.5 million wildebeest, along with zebras and gazelles, moving in a circular journey across the Serengeti ecosystem in search of fresh grass and water. This natural movement happens every year and is driven by seasonal rains. The migration starts in southern Serengeti, where animals give birth between January and March, then move northwest toward the Grumeti River, and later cross into Kenya’s Masai Mara before returning to Tanzania. One of the most dramatic moments is the river crossings, where animals risk their lives against strong currents and predators like crocodiles. The Great Migration offers amazing opportunities to see large herds, hunting scenes, and the cycle of life in the wild. It is a must-see experience for nature and safari lovers visiting Tanzania.
