The Great Migration in Serengeti National Park is one of the most spectacular wildlife events on Earth. Over 1.5 million wildebeest, accompanied by zebras and gazelles, move in a continuous circular journey between Tanzania and Kenya in search of fresh grazing land and water.

For travelers planning a safari, timing is everything. Depending on the month, you may witness dramatic river crossings, calving season, predator action, or endless plains filled with migrating herds.
