This two days tour includes game drive in the Tarangire National park and Ngorongoro crater. The name of the park originates from the Tarangire River that crosses the park. The Tarangire River is the primary source of fresh water for wild animals in the Tarangire Ecosystem during the annual dry season. The Tarangire Ecosystem is defined by the long-distance migration of wildebeest and zebras. During the dry season thousands of animals concentrate in Tarangire National Park from the surrounding wet-season dispersal and calving areas. The Ngorongoro Conservation Area is a protected area and a World Heritage Site located 180 km (110 mi) west of Arusha in the Crater Highlands area of Tanzania. The area is named after Ngorongoro Crater, a large volcanic caldera within the area. The conservation area is administered by the Ngorongoro Conservation Area Authority, an arm of the Tanzanian government, and its boundaries follow the boundary of the Ngorongoro Division of the Arusha Region.
