Descend into the Ngorongoro caldera very early in the morning to view the wildlife on the crater floor. The Ngorongoro Crater is often called “Africa’s Eden” and the “8th Natural Wonder of the World”. A massive extinct volcano, the sheet walls drop thousands of feet to a “Noah’s Ark” of animals on the verdant floor below. Large herds of zebra, buffalo, antelope, and wildebeest graze nearby while sleeping lions laze in the sun. At dawn, the endangered black rhino returns to the thick cover of the crater forests after grazing on dew-laden grass in the morning mist. The world-famous Ngorongoro Crater is at the eastern edge of the Serengeti in northern Tanzania. Nearly three million years old, the ancient caldera of the once-volcanic Ngorongoro shelters one of the most beautiful wildlife havens on earth, ringed with towering walls and sheltering forests, grasslands, fresh springs, and a large soda lake. Leave the crater late afternoon and drive back to Arusha for dinner and overnight
