From July, millions of wildebeest crest over the plains of the Serengeti on their ever-moving circuit where the thought of fresh grasses is enough to make them plunge across the flowing Grumeti and Mara Rivers. Drive across the savannah, led by your guide with a good nose for finding the action, and watch enthralled as life and death plays out before your eyes. The wildebeest gather like a storm on the southern banks before making a mad dash across the river, Nile crocodile snapping at their heels and big cats waiting to meet them on the other side. This display of pure nerve is one of the most epic events on the African safari calendar and you can easily spend an entire day out!
