Tourists from all over the world travel to Kenya's fantastic Masai Mara Game Reserve to watch the annual wildebeest migration, arguably one of the most spectacular natural sights on Earth. Each year, thousands of wildebeest in huge herds gather in Tanzania's Serengeti National Park before making the clockwise circular journey up into Kenya's Masai Mara Game Reserve in the eternal search for new grazing areas. And with the huge numbers of wildebeest come the predators making this a great time of year for wildlife watching.
