Mount Kilimanjaro with its three volcanic cones, Kibo,Mawenzi & and & Shira& is a dormant volcano in Tanzania. It is the highest mountain in Africa, and rises approximately 4,900 meters (16,100 ft) from its base to 5,895 meters (19,341 ft) above sea level. The first persons known to have reached the summit of the mountain were Hans Meyer and Ludwig Purtscheller in 1889. The mountain is part of the Kilimanjaro National Park and is a major climbing destination. The mountain has been the subject of many scientific studies because of its shrinking glaciers and disappearing ice fields.Kilimanjaro is the highest dormant volcano in Africa. Kilimanjaro is a large stratovolcano and is composed of three distinct volcanic cones: Kibo, the highest; Mawenzi at 5,149 meters (16,893 ft); and Shira, the shortest at 4,005 meters (13,140 ft). Mawenzi and Shira are extinct, while Kibo is dormant and could erupt again. Uhuru Peak is the highest summit on Kibo's crater rim.There are seven official trekking routes by which to ascend and descend Mount Kilimanjaro: Lemosho, Machame, Marangu, Mweka, Rongai, Shira, and Umbwe. Of all the routes, Machame is widely proclaimed as the most scenic, albeit steeper, route. This was true until the opening of Lemosho and Northern Circuit routes, which are equally scenic if not more. The Machame route can be done in six or seven days. Lemosho and the Northern Circuit routes can be done in seven or more days. The Rongai is the easiest and least scenic of all camping routes. The Marangu is also relatively easy, but this route tends to be very busy, the ascent and descent routes are the same, and accommodation is in shared huts with all other climbers.
