The wildebeest migration is a famous journey by the wildebeest from Serengeti national park across the Ndutu and seronera areas until they cross the danger zones of the Maraa River into Masai Maraa Plains. This migration is one of the Seven Wonders of the World. The world’s greatest wildlife migration, featuring up to 1.5 million wildebeest and thousands of zebra and gazelle, happens every year in East African countries of Tanzania and Kenya.
