The Ngorongoro Crater in northern Tanzania, once a gigantic volcano, is the largest intact caldera in the world. Some maintain that before it erupted, it would have been higher than Mt Kilimanjaro, the highest peak in Africa. Today, long since having collapsed and eroded, it is an extensive highland area with the famous 600 metre deep Ngorongoro Crater as its focal point. Nearly three million years old, the ancient caldera shelters one of the most beautiful wildlife havens on earth. Endangered black rhino are protected within its rim, giant tusked elephants wander the forests, black-maned lions stalk the grasslands, and flamingos crowd the soda lakes
