The Lemosho is the route Nyange Adventures recommends most consistently, and for straightforward reasons: it has the best acclimatisation profile of any route on the southern and western flanks, it passes through the most varied and scenic terrain on the mountain, and it is considerably less busy than the Machame despite being of comparable difficulty.

The route begins at Londorossi Gate on the western side of the mountain and spends the first two days crossing the Shira Plateau — a vast, open moorland at 3,600–3,840 metres that is one of the most visually distinctive landscapes on Kilimanjaro. Climbers then ascend to Lava Tower (4,600 m) before descending to Barranco Camp (3,950 m) to sleep — a textbook climb-high, sleep-low day that accelerates acclimatisation measurably.

The 8-day version adds a full rest and acclimatisation day at Shira Camp, which is the most significant difference from the 7-day. For climbers with any concern about altitude sickness, or those climbing Kilimanjaro for the first time, the 8-day Lemosho is the recommendation without reservation.

The Machame is the most climbed route on Kilimanjaro and has earned that status. It offers a strong acclimatisation profile, dramatic scenery through the Barranco Wall and the Karanga Valley, and a summit push from Barafu that many climbers find psychologically motivating. It is a challenging route — steeper and more technical in sections than the Lemosho — and suits climbers who are physically prepared and have some trekking experience.

The key feature of the Machame is its altitude rhythm: climbers ascend steeply each day to a high camp, then the route naturally loses altitude before the next ascent — the same climb-high, sleep-low dynamic that makes the Lemosho effective. The Barranco Wall, climbed on day four, is the most memorable single section on the route: a near-vertical scramble of around 300 metres that requires using both hands but involves no technical climbing.

The 7-day Machame is recommended over the 6-day. The extra day at Karanga Camp before the final push to Barafu makes a meaningful difference to acclimatisation and reduces summit-day fatigue. The 6-day itinerary is significantly harder on the body and is only appropriate for experienced high-altitude trekkers.

The Rongai is the only route that approaches Kilimanjaro from the north, beginning near the Kenyan border. This gives it a completely different character from the southern routes: the terrain is drier and more open, wildlife sightings — including elephant, buffalo, and colobus monkey — are more common in the lower zones, and the trail is significantly quieter than the Machame or Lemosho.

The acclimatisation profile is moderate rather than excellent. The route ascends at a more even gradient without the pronounced climb-high, sleep-low days that characterise the Lemosho and Machame. For climbers who respond well to gradual elevation gain and are not prone to altitude sickness, this works well. For those with altitude sensitivity, the Lemosho remains the stronger choice.

The Rongai descends via the Marangu route, which means climbers experience two different approaches to the mountain. This is considered a feature by many who enjoy the variety. The descent through the Marangu corridor is less dramatic than the southern flanks but straightforward and well-maintained.

The Marangu is the oldest established route on Kilimanjaro and the only one where climbers sleep in permanent wooden huts rather than tents. This gives it a different practical character — no wet sleeping gear, slightly warmer nights, communal dormitory spaces — and makes it marginally more accessible for climbers who are uncomfortable with camping. It is often marketed as the "beginner route" or the "Coca-Cola route," and that framing is misleading in one important respect: it has the lowest summit success rate of all six routes.

The reason is structural. The Marangu uses the same path for both ascent and descent, which means no natural variation in altitude between camps. There are no climb-high, sleep-low days. The standard 5-day itinerary gives the body very little time to acclimatise before the summit push, and the 6-day — which adds an acclimatisation day at Horombo Hut — improves the odds meaningfully. The 6-day Marangu is always recommended over the 5-day.

For experienced high-altitude trekkers who specifically want hut accommodation and are confident in their acclimatisation history, the Marangu is a legitimate option. For climbers whose primary goal is reaching the summit, one of the longer routes with a stronger altitude profile is the more rational choice.

The Northern Circuit is the longest route on Kilimanjaro and, by most measures, the best. It shares the Lemosho approach for the first two days before diverging northward to circumnavigate almost the entire mountain — covering terrain that no other route visits and passing through landscapes that the vast majority of Kilimanjaro climbers never see. It is the least trafficked route on the mountain by a significant margin.

The 9–10 day duration gives the body the most acclimatisation time of any route. The gradual, extended altitude gain — covering the mountain's full northern arc at altitudes between 3,500 and 4,200 metres for several days before the final push — results in summit success rates consistently above 90% with a well-managed operator. For climbers who have previously attempted Kilimanjaro and not summited due to altitude issues, this is the route most likely to change that outcome.

The trade-off is cost and time. The Northern Circuit requires two to three additional days compared to the Lemosho and Machame, which increases park fees, crew costs, and the total investment. For climbers who can accommodate the schedule, it is the most complete experience the mountain offers.

The Umbwe is the most direct and most physically demanding route on Kilimanjaro. It gains altitude faster than any other route on the mountain — climbing steeply through dense rainforest and heath in the first two days, reaching camp altitudes that other routes take three to four days to achieve. This makes it simultaneously the most challenging route for experienced mountain trekkers and the worst choice for summit success due to its compressed acclimatisation time.

The route is genuinely remote and very quiet. Climbers on the Umbwe encounter far fewer other groups than on any southern route, and the steep, rooted forest section in the lower zones is considered among the most atmospheric trail environments on the mountain. It joins the Lemosho and Machame routes on the upper mountain, ascending via the Barranco Valley and summit via Barafu.

Nyange Adventures recommends the Umbwe only to climbers with significant high-altitude experience, a strong prior acclimatisation history, and a specific reason to choose this route over the Lemosho or Machame. For the majority of climbers, the Umbwe's lower success rate and harder physical demands are not a worthwhile trade for its quieter trail and dramatic lower-mountain terrain.
