Walking safari Arusha National Park – Full day. A safari walk through Arusha National Park that lasts between 6 and 8 hours is said to be memorable. With the help of a knowledgeable park guide, you can get close to giraffes, buffalo, zebras, warthogs, and blue monkeys while learning about the park’s unique plants and animals. As an example, you go by Lake Momella, the Ngurdoto Crater, and a beautiful waterfall. You might also see birds in groups and the beautiful Colobus monkey swinging through the trees if you come at the right time.
