A safari big hitter, Tanzania’s ‘Northern Circuit’ is another top safari area that can be navigated by road. Starting in Arusha, you’ll go through jaw-dropping spots like Lake Manyara National Park and two of the most outstanding wildlife reserves in the world: the Serengeti and Ngorongoro Crater. The Crater has some of the easiest Big 5 game viewing in the world – it’s not unusual to see elephant, leopard, lion, buffalo and rhino on a single game drive – and the Serengeti is, of course, famous for the annual Wildebeest Migration from about December to June, depending on where you go.
