Ngorongoro Crater is located in the Ngorongoro Conservation Area, a UNESCO World Heritage Site encompassing 8,300 square kilometers. It is unique as an area where human beings and domestic and wild animals all peacefully coexist.

The area’s main crater is an unbroken, unflooded caldera that was formed when a volcano erupted and collapsed approximately 3 million years ago. The crater has a depth of 610 meters and a base area that covers 260 square kilometers. The original volcano is estimated to have been 4,500 to 5,800 meters high.
