Summary

TLDREach year, the Serengeti Plains in Tanzania witness one of the greatest animal migrations on Earth, with around 2 million wildebeest and other animals traveling nearly 2,000 miles. The migration begins early in the year when the wildebeest gather and give birth. Despite the dangers of predators and the challenges of the trek, the herd pushes forward, with around 200,000 animals dying from exhaustion or disease. They eventually reach Kenya's Masai Mara, where they graze until the November rains signal it's time to return to the Serengeti.
