The Ngorongoro Crater is the world’s largest volcanic crater. More than 2,5 million years ago, Ngorongoro was a volcanic mountain, the size of Kilimanjaro, and one of the highest peaks of Africa. When its top collapsed it transformed into a gigantic inactive volcano. Today the crater forms a bowl of 20 kilometres (12,5 miles) wide with sides up to 600 metres (2,000 feet) deep. Enjoy the phenomenal views from the rim over the crater floor, before you drive in. Lake Manyara National Park is located 126 km (78 mi) south west of Arusha] and can be reached by car in an hour and a half. The park can also be reached from Babati the capital of Manyara Region. Lake Manyara Airport is nearby. To the south of the park is the 35,399 ha Marang Forest Reserve, situated on the escarpment above the park. To the east is the Kwa Kuchinja Wildlife Migration corridor, which allows wildlife to migrate between the near-by Tarangire National Park to the southeast, Lake Manyara to the west.
