The wildebeest migration was spotted grazing along the Grumeti River in the Western Serengeti. However, a large number of herds have started crossing the Grumeti River along the Nyasirori Bridge heading into the Nyasirori Plains.
Every year, the herds visit this area in search of green grass and water along the Grumeti River. This is where the herds prepare for mating on their way to the northern Serengeti.
