Experiencing any part of this incredible natural spectacle is truly the greatest safari experience you could wish for. Whether you're enjoying watching hundreds of thousands of young wildebeest calves on the plains of the Serengeti; witnessing the great river crossings; or simply enjoying the vast numbers of wildlife on the Mara plains -- it's all pretty fantastic.
