About Ngorongoro Crater

The world's largest intact volcanic caldera, Ngorongoro is a bowl of grassland and forest where elephant, lion, rhino and flamingos live year-round. The rim road looks straight down into it, and Olduvai Gorge, where early human fossils were found, lies on the way to the Serengeti. June to October is dry and clearest; the long rains fall from March to May, when tracks turn muddy and crowds thin.
