The benefit of the eastern circuit is that it offers visitors based in Dar es Salaam a chance to see the wildlife and scenery the country has to offer without the expense and time involved in flying to Arusha for a longer safari. Parks like Saadani and Mikumi grow in popularity every year, and the Mafia Island Marine Park is fast becoming a hot destination in the Indian Ocean. The national parks, game reserves, and marine parks of the eastern circuit are perfect weekend retreats for guests on business-related trips to Dar es Salaam.
