The Great Migration ranks high on many safari lists! Picture yourself watching over two million wildebeest, zebras, and gazelles move across the Serengeti-Masai Mara system. The most gripping scenes happen at river crossings, where vast herds face crocodile-filled waters in their constant search for better grazing. Plan your visit between July and October for the best chances to see these amazing river crossings. This natural wonder gives outstanding photo chances and pulse-racing wildlife action.
