Kilimanjaro, the highest permanently snow-capped free standing mountain in Africa can offer a challenge to walkers and climbers alike with its peak standing at almost 6km in height. Other must-sees include the Arusha National Park with its volcanic features and lakes, the exotic Islands of Zanzibar, the finest game sanctuaries of Serengeti, Tarangire, Lake Manyara, Ngorongoro Crater, Ruaha, Selous and the Marine Park of Mafia Island are only but a few of the living examples. Just imagine viewing the famous tree climbing lions in the country's northern parks! The aim of the government of Tanzania is to develop tourism in an eco-friendly, sustainable manner.
