The biggest annual event in Kenya is the migration, where huge herds of wildebeest head from Tanzania’s Serengeti National park into Kenya’s Masai Mara in search of greener pastures. Entering Kenya in late July/August each year, more than 2 million of these animals migrate across the Mara River into Kenya accompanied by zebras, antelopes, gazelles and lions. In October/November the animals return to the short grass plains. The highlight of the migration is watching the animals crossing the Mara River in Kenya.
