Mount Kilimanjaro

Kilimanjaro: The Mountain That Kills the Unprepared and Rewards the Patient

Roughly 35,000 people attempt Mount Kilimanjaro every year. The overall success rate for all climbers, across all operators, hovers between 60 and 80 per cent. The most common reasons people fail to reach Uhuru Peak at 5,895 metres are entirely preventable: not enough days on the mountain, ascending too quickly, and treating it as a hiking trip rather than a high-altitude expedition. Kilimanjaro has no technical climbing. It requires no ropes, crampons, or special skills. What it requires is time.

The Glaciers Are Disappearing

Since 1912, when continuous measurement of Kilimanjaro’s ice coverage began, the mountain has lost approximately 85 per cent of its summit ice. The northern ice field, which visitors often photograph against the blue equatorial sky, contains air bubbles more than 11,000 years old that researchers have used to reconstruct ancient climate data. Researchers now estimate that what remains may be gone by 2050, possibly earlier. The cause is partly a documented shift in Indian Ocean atmospheric dynamics in the late 19th century that reduced moisture flowing into East Africa; human-driven warming has sustained and accelerated that process. Climbers today are seeing what future generations will only know from photographs.

The mountain is a dormant stratovolcano with three peaks: Kibo, the highest and the one with the summit crater; Mawenzi, a jagged rocky peak to the east; and Shira, a broad plateau to the west. Kibo’s crater rim contains the Reusch Crater, and within that, the Ash Pit, which last showed volcanic activity around 150 years ago.

Routes and Why the Choice Matters

Kilimanjaro National Park manages all climbing through licensed operators; self-guided ascents are not permitted. Park fees alone run roughly $700 to $1,000 per person depending on the route length (calculated at $70 per day conservation fee plus a forest fee and rescue fund contribution). The total cost of a reputable guided climb including operator fees, guides, porters, food, and camping equipment typically runs $3,000 to $5,000 per person. Budget operators offering climbs below $2,000 generally cut corners on acclimatisation days, guide qualifications, or porter welfare. The cost difference between a cheap operator and a reputable one is much smaller than the cost of a second attempt.

Route selection directly affects your chances of summiting:

The Machame Route (7 days) is the most popular route and reasonably well-designed for acclimatisation, with an average success rate around 85 per cent for properly paced groups. Scenic, varied terrain through rainforest, moorland, and alpine desert.

The Lemosho Route (8 days) starts further west and is longer, quieter, and better for acclimatisation. Success rates are consistently above 90 per cent. The extra day costs more in park fees but is among the better investments you can make on this mountain.

The Northern Circuit (9 days) circles the mountain at altitude before the summit attempt, providing the best possible acclimatisation profile. It is the longest route and sees the fewest climbers.

The Marangu Route (5-6 days) uses huts rather than tents and is marketed as the easiest route. It actually has among the lowest success rates, around 65 per cent, because the itinerary is too short for most people to acclimatise properly. The hut accommodation is less significant than the time on the mountain.

Altitude and Acclimatisation

Acute Mountain Sickness affects up to 75 per cent of Kilimanjaro climbers to some degree. The difference between mild symptoms (headache, fatigue, poor sleep) and serious illness (vomiting, confusion, pulmonary or cerebral oedema) lies primarily in how fast you ascend. The standard advice is to choose a longer route, move slowly, drink 3-4 litres of water per day, and eat even when appetite fails. The phrase guides use is “pole pole” (slowly slowly in Swahili), and they mean it literally.

Some climbers take Diamox (acetazolamide) as a preventative. It accelerates acclimatisation by stimulating faster breathing, but it causes increased urination and, in some people, tingling in fingers and lips. It is not a substitute for a longer route. Anyone who develops confusion, is unable to walk a straight line, or experiences persistent vomiting should descend immediately regardless of where they are on the mountain.

The summit attempt typically leaves high camp (Barafu or Kosovo Camp, around 4,600-4,800 metres) between midnight and 2am to reach the crater rim at dawn. Temperatures at this altitude and hour can drop to -20C. Wind chill makes it colder. The combination of cold, fatigue, and altitude at this stage of the climb is where most turnarounds happen. Preparation matters.

Before and After the Climb: Moshi

The town of Moshi, at roughly 900 metres on Kilimanjaro’s southern slopes, is where most climbs depart and most climbers stay pre- and post-trek. It is a genuine Tanzanian market town rather than a tourist bubble.

Chanya Lodge, six kilometres from the town centre, has a pool and garden and is consistently recommended for its gear storage facilities and its willingness to deal with early departure logistics. Kilimanjaro Serena Hotel is the most comfortable option in town and useful for recovery after the descent, when a proper bed and unlimited hot water are genuinely appreciated. Aishi Machame Hotel, 15 minutes from the Machame Gate trailhead, is practical for groups on that route.

For eating, the Jackfruit Cafe in town is reliable for lighter meals and has options for dietary restrictions, which matters when climbers are trying to carb-load or avoid heavy food before departure. Khan’s BBQ for grilled meats is the most popular evening option for post-climb celebration. The Keys Restaurant has a terrace with partial mountain views and an international menu.

Best Time to Climb

Kilimanjaro can be climbed year-round. The two main dry seasons are January to March (the best overall weather window) and June to October (the longer peak season). April and May see the long rains and are generally avoided. November brings shorter rains. The mountain’s weather is highly localised and can change rapidly regardless of season. Booking 6 to 12 months in advance for the peak June-October window is advisable for both climb slots and Moshi accommodation.

Wildlife on the Lower Slopes

The lower elevation zones, particularly the rainforest belt between roughly 1,800 and 2,800 metres, hold colobus monkeys, blue monkeys, bushbuck, and a dense bird population including Hartlaub’s turaco, which is as spectacular as its name suggests. Most organised climbs pass through this zone quickly. It is worth slowing down here deliberately.

Operator Selection

Tanzania’s national body for mountain operators, KPAP (Kilimanjaro Porters Assistance Project), audits operators for porter treatment and working conditions. Choosing a KPAP Partner operator is the clearest single signal that an operator is running the mountain responsibly. The difference in price between a KPAP operator and an unvetted budget operator is rarely large in the context of the overall trip cost.

If you take only one piece of advice about Kilimanjaro: book more days than you think you need, choose a reputable operator, and go slowly. The mountain does not reward speed.
