In this episode of Travels to the Edge with Art Wolfe, Art visits one of the earth’s most extreme environments — East Africa. This part of the world is a vast stage on which the circular, never-ending journey known as the Great Migration has played out for millions of years. After going eye to eye with thousands of wildebeest and zebra, Art enlists an old friend and bush pilot to help him capture in images aerial patterns of migrating herds and flocks of flamingos. On the ground, he pursues giraffe on horseback and tracks rhino on foot. This is one of the most exciting and picturesque episodes from the television series. See Art's video introduction to this episode.
