After breakfast, your safari continues to the Ngorongoro Crater, a UNESCO World Heritage Site. This is the world’s largest caldera, a feature formed by the collapse of land after a volcanic eruption. It is approximately 18 km in diameter and home to about 25,000 mammals. In this relatively small area you can find almost all the mammals of East Africa ranging from Grant’s and Thomson’s gazelles to mountain reedbucks in the forests on the slopes. You might also see spotted hyenas, rare wild dogs and some of the more than 500 bird species of the area. It is also possible to spot the Big Five – lion, elephant, buffalo, rhino and leopard – in the few hours spent in the crater. After lunch at a picnic spot, there will be more time to continue your game drive before you leave the crater and return to Arusha by the early evening.
