The Great Wildebeest Migration Journey Unpacked

The journey commences in the southern plains of Tanzania’s Serengeti National Park in December, coinciding with the onset of the rainy season. During this period, a substantial number of wildebeest are born, and as the herds replenish, they commence their movement towards the west and then north in search of more fertile grazing grounds. By July, the herds have arrived at the Grumeti River in the Serengeti and the Mara River, which acts as a natural boundary between Tanzania and Kenya. These river crossings are highly captivating spectacles, as the wildebeest face formidable currents and the presence of lurking crocodiles. Following the successful crossing of the Mara River, the herds spend a period of time in the abundant plains of the Maasai Mara National Reserve before returning to the Serengeti to complete their migratory cycle.

Mara River crossing

Mara River crossing is the most exciting, terrifying, and deadly episode of the great wildebeest migration as thousands of herds (wildebeests, zebras, Thomson, and grant’s gazelles) cross over from Serengeti national park to the plains of Maasai Mara national reserve. As they cross, the animals face-off with the deadly crocodiles in the waters of Mara River which are ready with their sharp teeth to feast on the herds. It is believed that a quarter of the migrating herds survive the deadly cross and after crossing the survivors also face off with predators waiting on the banks of the river that is lions, cheetahs, leopards, and African dogs.
