The Serengeti is famed for its annual migration when more than 1,500,000 wildebeest and 500,000 Thomson Gazelle follow some 200,000 zebra in a 2,000 km round pilgrimage in search of fresh grazing and water .
It is ``the greatest wildlife show on earth `` and ``a once in a lifetime experience ``!
The best time to see the migration is between June and August when the wildebeest congregate and prepare to cross the Grumeti River .
However ,both the route and timing of migration are unpredictable so the visitors must plan to be assured of seeing the spectacle.
During December to May the animals are found on the short glass plain around lake NDUTU , the GOL Mountains and the Moru Kopjes in the south of the park. December is a peak month for zebra foaling and February the main month for wildebeest calving.
Then the migration start as vast migration herds, in columns over 40km long , head north towards Kirawira and Mbalageti , in the western corridor , before crossing the crocodile infested Grumeti River into the Grumeti Game Reserve and Ikorongo wildlife Management Area.
Meanwhile some smaller herds move directly north through Seronera area,while others travel up the eastern boundary of the park through the Loliondo and Lobo areas.
All routes eventually crossing the Mara River, where the animals face another life threatening experience , into Kenya`s Masai Mara.
Finaly , in November , the herds start their trek back through serengeri arriving at the short grass plains ready to give birth again. And so the cycle continues ! As it has for over a million years!
