The Serengeti Great Migration is one of the most amazing wildlife events in the world. Every year, more than 1.5 million wildebeest, along with hundreds of thousands of zebras and gazelles, travel across the Serengeti in Tanzania and the Maasai Mara in Kenya in search of fresh grass and water. This incredible journey happens all year, so there is always something exciting to see. Whether you want to watch newborn calves, dramatic river crossings, or predators in action, this guide will help you choose the best time for your safari.
