Mount Kilimanjaro or just Kilimanjaro with its three volcanic cones, “Kibo”, “Mawenzi”, and “Shira”, is a dormant volcano in Tanzania. It is the highest mountain in Africa, about 4,900 metres (16,100 ft) from its base to 5,895 metres (19,341 ft) above sea level. The first people 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.There are seven official trekking routes by which to ascend and descend 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 can be done in six to eight days, 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.People who wish to trek to the summit of Kilimanjaro are advised to undertake appropriate research and ensure that they are both properly equipped and physically capable. Though the climb is technically not as challenging as when climbing the high peaks of the Himalayas or Andes, the high elevation, low temperature, and occasional high winds make this a difficult and dangerous trek. Acclimatization is essential, and even the most experienced trekkers suffer some degree of altitude sickness.
