The 40,000 sq km Serengeti-Mara plain that straddles the border of Kenya and Tanzania is famous for its abundant and diverse wildlife. It is also home to one of the wonders of the world: the Serengeti-Mara wildebeest migration. Each year about two million wildebeest, zebra and gazelles migrate from Tanzania to Kenya’s Maasai Mara in search of food and water.

Every year, a sense of anticipation hangs over the grassland savannahs of East Africa.

Wildebeest – large African antelopes with distinctively curved horns – are famous for their great migrations on the grasslands of eastern and southern Africa.

Understanding what the environment looked like millions of years ago is essential for piecing together how our earliest ancestors lived and survived.

The Great Wildebeest Migration is one of the most remarkable natural spectacles on Earth.
