Mount Kilimanjaro is actually a dormant volcano. Its two peaks stand about 11 km (about 7 mi) apart and are connected by a broad ridge. The highest peak, Kibo, rises to 5895 m (19,340 ft) above sea level, and the summit of Mawensi is 5149 m (16,892 ft) above sea level.Although Kilimanjaro is only 3 degrees south of the equator, an ice cap covers the crater of Kibo year-round. This mountain and it's ice cap was the inspiration for Ernest Hemingway's famous novel: "The Snows of Kilimanjaro" (1938).

Trekking Mount Kilimanjaro :-
There are six official trekking routes by which to climb Mt Kilimanjaro, namely: Marangu, Rongai, Lemosho, Shira, Umbwe and Machame. Of all the routes, Machame is by far the most scenic albeit steeper route up the mountain, which can be done in six or seven days. The Rongai is the easiest and least scenic of all camping routes with the most difficult summit night and the Marangu is also relatively easy, but accommodation is in shared huts with all other climbers. As a result, this route tends to be very busy, and ascent and descent routes are the same.
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. Acclimatisation is essential, and even the most experienced trekkers suffer some degree of altitude sickness. Kilimanjaro summit is well above the altitude at which high altitude pulmonary edema (HAPE), or high altitude cerebral edema (HACE) can occur. All trekkers will suffer considerable discomfort, typically shortage of breath, hypothermia and headaches.
High-altitude climbing clubs—citing safe ascent rate suggestions offered by organisations such as the Royal Geographical Society—have criticised the Tanzanian authorities for charging fees for each day spent on the mountain. It was once argued that this fee structure encouraged trekkers to climb rapidly to save time and money, while proper acclimatisation demands that delays are built into any high climb. However, in response to this accusation, Tanzania National Parks Authority several years ago mandated minimum climb durations for each route. These regulations prohibit climbs of fewer than five days on the Marangu Route, and ensure a minimum of six days for the other five sanctioned routes. These minimums—particularly in the case of Marangu, which ostensibly allows that Uhuru Peak (5,895m) can be reached from a starting elevation at 1,860m within 72 hours of beginning the ascent—are reckoned by most alpinists to allow an ascent rate that will usually result in the climber failing to acclimatize adequately, by the time that Kibo Huts are reached; the launch base from which the summit is assaulted. Consequently, the incidence of Acute Mountain Sickness (AMS) is widely deemed to be unacceptably high on Kilimanjaro, with high volumes of fit young people succumbing to the condition, having opted for a relatively rapid ascent. As a general rule, it is far safer (and more enjoyable) to avoid altitude sickness by planning a sensible itinerary that allows for gradual acclimatisation to high elevation as one ascends. Operations that typically see in excess of a thousand climbers summitting annually and are best placed to identify such patterns, usually posit that an optimal climb length should last around seven to eight days.
Tanzanian Medical Services around the mountain have expressed concern recently over the current influx of tourists that apparently perceive Kilimanjaro as an easy walk. However this is not the case. Many individuals require significant attention during their attempts, and many are forced to abandon the trek. An investigation into the matter concluded that tourists visiting Tanzania were often encouraged to join groups heading up the mountain without being made aware of the significant physical demands of the climb, although many outfitters and tour operators flaunt high success rates for reaching the summit. The Kilimanjaro National Park shows that only 41% of trekkers actually reach the Uhuru summit with the majority turning around at Gilman’s Point, 300 metres (980 feet) short of Uhuru, or Stella Point, 200 (660 feet) meters short of Uhuru. Kilimanjaro is often underestimated because it can be walked and is not a technical climb. However, many mountaineers consider Kilimanjaro very physically demanding.
Some estimate that more people have died to date trekking up Kilimanjaro than Mount Everest but Everest is attempted by significantly fewer climbers. In August 2007 four trekkers died within a week underscoring the point that trekking to the summit should not be taken casually. Multiple people (trekkers, porters, and guides) die on the mountain each year. The majority of these deaths are porters, from hypothermia. Trekkers fall on steep portions of the mountain, and rock slides have killed trekkers. For this reason, the route via the Arrow Glacier was closed for several years. It re-opened in December 2007, but the park officials advise against taking that route and tell trekkers that they can climb, but at their own risk. When attempting the Arrow Glacier route, trekkers must leave early in the morning and make it past the rock face before mid-afternoon as when the sun comes out, unfrozen rock slides become quite common.
Unique Vegetation:-
Being an Afromontane sky island, Kilimanjaro has an enormous biodiversity while low in endemic species. However endemics include the giant groundsels in the bunchgrass tussock grasslands, and other flora adapted to living in alpine plant conditions.
Kilimanjaro has a large variety of forest types over an altitudinal range of 3,000 m (9,843 ft) containing over 1,200 vascular plant species. Montane Ocotea forests occur on the wet southern slope. Cassipourea and Juniperus forests grow on the dry northern slope. Subalpine Erica forests at 4,100 m (13,451 ft) represent the highest elevation cloud forests in Africa. In contrast to this enormous biodiversity, the degree of endemism is low. However, forest relicts in the deepest valleys of the cultivated lower areas suggest that a rich forest flora inhabited Mt Kilimanjaro in the past, with restricted-range species otherwise only known from the Eastern Arc mountains. The low degree of endemism on Kilimanjaro may result from destruction of lower elevation forest rather than the relatively young age of the mountain.
Another feature of the forests of Kilimanjaro is the absence of a bamboo zone, which occurs on all other tall mountains in East Africa with a similarly high rainfall. Sinarundinaria alpina stands are favoured by elephants and African buffalos elsewhere. On Kilimanjaro these megaherbivores occur on the northern slopes, where it is too dry for a large bamboo zone to develop. They are excluded from the wet southern slope forests by topography and humans, who have cultivated the foothills for at least 2000 years.This interplay of biotic and abiotic factors could explain not only the lack of a bamboo zone on Kilimanjaro but also offers possible explanations for the patterns of diversity and endemism. If true, Kilimanjaro's forests would serve as a striking example of the large and long-lasting influence of both animals and humans on the African landscape.
