This park has three distinct zones: Ngurdoto Crater (often called the ‘mini-Ngorongoro’); the shallow alkaline Momella Lakes fed by underground streams (upon which rest thousands of lesser and greater flamingoes, and many migrant birds can be seen between May and October); and the densely forested slopes of Mount Meru (one of the rewarding mountains to climb in Africa and where, among other animal species, live blue monkeys and beautiful black and white colobus monkeys). Other attractions in the park include the elephant, giraffe, buffalo, zebra, hippo, various antelopes, leopard and hyena. The park is 21 km from Arusha on the main Arusha to Moshi road. A network of gravel roads and tracks navigable by two wheel-drive vehicle link the park’s main features and viewing points. Nevertheless, a few roads require 4WD vehicles.
