The Grumeti Woodlands play host to the most amazing wildlife spectacle in Africa. Every year, thousands of wildebeest take the cold plunge to cross the glittering waters of the Grumeti River, the centerpiece of the Grumeti Woodlands. The river itself is renowned for its population of gigantic Nile crocodiles. Some of these pre-historic monsters measure up to 17-feet long and are 70-years old!
