Often dubbed the Eighth Wonder of the World, the annual Wildebeest Migration sees more than a million wildebeest and zebras make the trip from Tanzania's Serengeti into Kenya's Maasai Mara.No where in the world is there a movement of animals as immense as the wildebeest migration, over two million animals migrate from the Serengeti National Park in Tanzania to the greener pastures of the Maasai Mara National Reserve in Kenya during July through to October.The migration has to cross the Mara River in the Maasai Mara where crocodiles will prey on them. This is one of the highlights as the animals try and cross the Mara River alive.
