Maybe your local zoo has lions, leopards, zebras or elephants. Maybe they even have wildebeest. But we bet they don't have 1.3 million wildebeest—never mind 1.3 million wildebeest in migration, with predators in hot pursuit. It's one of the most awesome sights in nature, and you can see it at Masai Mara in southwestern Kenya.

The Maasai call the plains of Serengeti National Park "the place where the land moves on forever"—so prepare to be astonished by its vastness. And here, you can witness the famous Serengeti annual migration, the largest and longest overland migration on earth.
