The Great Wildebeest Migration is one of the most spectacular wildlife events on Earth. Every year, over 1.5 million wildebeest, accompanied by zebras, gazelles, and other grazers, move in a circular pattern between Tanzania’s Serengeti National Park and Kenya’s Masai Mara National Reserve.
This epic journey is driven by the search for fresh grazing lands and water, making it a year-round natural wonder rather than a single event. Along the way, the animals face dramatic river crossings, predators waiting for their chance, and the challenges of survival in the wild.
