One needs to fly to Kilimanjaro International Airport at Moshi, situated at the foot of Mount Kilimanjaro. From there one can get a charter flight, take a taxi or make use of the free shuttle service. The distance from Moshi to Arusha is about 55km.
Take note: The road from Arusha to Lodoare Entrance Gate is 160km long. As of recently, the entire journey is on tarmac and it takes about two hours. Unless you stay on the main roads, which are graveled, a 4x4 vehicle is essential when entering the Ngorongoro Conservation Area and the Serengeti National Park.
