The Great Wildebeest Migration is an annual event where over a million wildebeest travel between Serengeti National Park in Tanzania and Maasai Mara National Reserve in Kenya. It is a must-see safari experience and one of the world's greatest natural wonders.

The migration typically begins in July and continues until late September, though exact dates vary depending on weather conditions, climate, and the movement of the animals.

This spectacle takes place within the Serengeti-Maasai Mara ecosystem. The herds are often spread across vast areas, with many gathering on the southern banks of the Grumeti River before crossing. They also cross the Mara River multiple times over several months, creating dramatic scenes as they navigate through the water, often facing predators along the way.
