The Ngorongoro Conservation Area of Tanzania stretches 8,300 square kilometers and boasts a blend of people, archeology, landscapes, and wildlife. Here you will find the Ngorongoro Crater, which is one of the greatest natural spectacles in the world and is considered to be the world’s 8th wonder. The crater is located on the border of the Serengeti National Park and is only a few hours away from Arusha, which is a town located at the bottom of Mount Meru. Ngorongoro Crater is one of the World Heritage Sites and is the biggest unbroken ancient caldera worldwide. It is almost 3 million years old and is now considered to be the Garden of Eden in Africa. Before the Ngorongoro volcano exploded, collapsing 2 million years ago, it was one of the tallest mountains in the world. The crater actually measures 12 million inches diameter and the rim is 2,000 feet above the floor of the crater.
