The Northern Circuit Route
The longest route on the mountain, following Lemosho onto the plateau then swinging right round the quiet northern slopes before the summit push. Usually eight or nine days. It is the longest itinerary on the mountain, which is the real distinction; the summit success rate it is marketed on has never been independently measured.
The Northern Circuit is the newest trail on Kilimanjaro and the only one that goes most of the way round the mountain. It begins as a Lemosho itinerary, then turns away from the crowded southern traverse and spends three or four days crossing the dry, empty northern slopes before climbing to Uhuru Peak from the east. It is the longest itinerary the park sells, which is the entire argument for it — and, contrary to what you will read almost everywhere, nobody has ever published a measured summit rate for it. This guide covers the route, the northern country, and what the length genuinely does for you.
Northern Circuit Route Guide in Tanzania
The newest route, and the longest
The Northern Circuit is the most recent addition to Kilimanjaro's trail network and it is the only itinerary that goes most of the way round the mountain. Where every other route picks a flank and climbs it, this one climbs the western side, refuses to turn south with the traffic, and instead traverses the entire northern face before coming back to the summit from the east.
TANAPA's stated range for reaching Kibo is five to nine days depending on the route. The Northern Circuit sits at the top of that range, and it is normally sold at nine days or occasionally more. That length is the whole product. Everything else about the route follows from it.
Where it goes
For its first third the Northern Circuit is a Lemosho itinerary. It enters at Londorossi, drives up the forestry track to the Lemosho Glades, and spends two days walking up through the western forest and onto the Shira Plateau — the collapsed remains of Kilimanjaro's oldest volcanic centre, whose surviving peak stands at 3,962 metres and whose open shelf TANAPA records as holding buffalo, elephant and eland. Those two days are described on the Lemosho guide and are not repeated here.
The divergence comes at the eastern end of the plateau. A Lemosho or Machame group turns right, onto the busy southern traverse. A Northern Circuit group turns left.
From there the route swings anticlockwise around Kibo's northern flank, spending three or four days on ground that almost nobody else on the mountain is walking. It works its way east across the northern slopes, comes round beneath the Kibo–Mawenzi Saddle, and turns up to a high camp on Kibo's eastern side. Summit night climbs from there to the crater rim and round to Uhuru Peak at 5,895 metres. The descent, like almost everything else, goes down the southern side and out through Mweka Gate — so you finish having walked nearly a complete circle around the mountain and never once retraced your steps.
The northern slopes
The north of Kilimanjaro is a different mountain from the one in the photographs, and this is the only route that shows it to you at length.
The southern and western flanks catch the weather; the northern ones sit in their rain shadow. The result is dry, open, high country — brown and gold rather than green, with sparse vegetation, long views out over the plains towards the Kenyan border, and very little between you and the horizon. Because the route contours around rather than climbing directly, you spend days at a fairly constant altitude looking at Kibo from angles that most climbers never see, including the northern ice fields that are invisible from the standard routes.
It is also silent in a way the southern side is not. There is no queue, no procession of head torches, no camp of two hundred tents. On the quietest sections you may go most of a day without meeting another group.
The profile, and why length is the argument
Nine days on the mountain means eight nights, most of them above 3,000 metres and several of them above 4,000. Because the northern traverse contours rather than climbs, those nights come with a lot of walking at altitude and relatively little net height gain — which is, in acclimatisation terms, close to ideal. You are giving your body days of stimulus at moderate altitude before asking it to go high.
TANAPA's own material states the principle plainly: the more days you take, the higher the possibility of reaching the summit. The published research on Kilimanjaro points the same way, with the short four- and five-day profiles producing poor outcomes and a longer, gentler itinerary doing substantially better in the one cohort where it was measured. All of that evidence is set out in the main Kilimanjaro climbing guide.
So the case for this route is strong and it is a case about mechanism: more nights high, a gentler gradient, and no compressed push at the end. What those extra nights add to the fee stack, since the conservation fee is charged by the day, is set out in what a Kilimanjaro climb costs before an operator adds anything.
About that success rate
You will read almost everywhere that the Northern Circuit has the highest summit success rate on Kilimanjaro, usually quoted at somewhere between 90 and 95 per cent.
Nobody has measured it. There is no published study of outcomes on this route, and there is no public dataset from the park broken down by route. The percentages in circulation are operator estimates of their own clients, repeated until they acquired the appearance of a statistic. Some of them may well be roughly right. None of them is a measurement, and this site will not print one.
What can be said honestly is this: the Northern Circuit gives you more nights at altitude than any other itinerary on the mountain, the relationship between more nights and better summit odds is supported both by the park's own guidance and by the peer-reviewed work that does exist, and there is no reason to think this route is worse than the alternatives. That is a genuine argument for it. It is just not a number.
It is also worth noting the thing the research is clear about in the other direction: longer itineraries have not been shown to reduce how often people feel ill. One retrospective study of 917 trekkers found that two extra days made no difference to the prevalence of altitude symptoms. Expect the extra days to improve your chances of standing on the summit, not to make the week pleasant.
The summit approach is not the standard one
Most routes on Kilimanjaro converge on the same ridge at Barafu and start summit night from there. The Northern Circuit arrives at the summit cone from the eastern side instead, from a high camp beneath Kibo's eastern scree, and this changes two things worth knowing in advance.
The first is company. Starting from a different camp on a different side means you climb through the small hours with your own group rather than in a procession. For some people that is the best part of the trip; for others the absence of a line of head torches above them removes a useful psychological handrail, and it is worth knowing which sort you are.
The second is the descent. Having come up from the east, you cross the summit area and go down the southern side, out through Mweka Gate, so the last day and a half is on ground the rest of the mountain is also using. The circle closes on the busiest path in the park, which is a slightly deflating way to finish a week of solitude and is also the fastest way down.
One practical consequence: because your ascent and descent are on opposite sides of the mountain, everything you need has to travel with you the whole way. There is no version of this route where a vehicle meets you at a halfway point.
Solitude, and what it costs
The emptiness of the northern slopes is the route's second selling point and it has a flip side worth understanding before you commit.
Fewer groups means fewer crews, fewer guides within earshot, and more distance between you and help. Kilimanjaro's mountain stations carry first aid and radio, and the park's rescue infrastructure exists, but a problem on the northern traverse is further from a road head than the same problem on the Barafu ridge. If you or anyone in your party has a medical history that makes an evacuation plan a real consideration rather than a formality, discuss it specifically with your operator before choosing this route rather than after.
The other cost is time. Nine days on the mountain plus travel is close to a fortnight, and that is before any safari or coast leg. How a climb and a safari fit into one trip, and which of them should come first, is worth settling before the route is booked. For most travellers this route competes not with Lemosho but with the rest of their trip.
Who it suits
It suits anyone whose limiting factor is not the calendar: people who want the best acclimatisation profile available, who have failed on a shorter route before and want to change the variable that actually matters, who are over 50 or climbing with a group of mixed fitness, or who simply want the mountain to themselves for half the trip. It suits photographers, because the northern aspect of Kibo is genuinely unfamiliar. And it suits anyone adding a night in the caldera, since the acclimatisation this route provides is the precondition for Crater Camp.
Look elsewhere if nine days is not available, in which case Lemosho is the same route's first third with a conventional finish and is a very good trip. Look elsewhere if you want the classic southern scenery — the Barranco valley under the glaciers is on Machame and Lemosho, and this route skips it. And if what you want is the northern side without the full circuit, Rongai approaches from the north-east in far fewer days.
Common questions
Is the Northern Circuit harder than the other routes?
No. It is longer, but the daily distances are moderate and the gradient is gentle — the northern traverse contours rather than climbs. The physical demand is spread over more days, not concentrated.
Is it the same as Lemosho?
For the first two or three days, yes. It enters at Londorossi and crosses the Shira Plateau exactly as Lemosho does. The two part company at the eastern edge of the plateau, and everything after that is different.
Does it really have the highest success rate?
Nobody has published a measurement, and the figures you will see quoted are unsourced. It is the longest itinerary on the mountain, and both TANAPA's guidance and the published research support the principle that more days improves your chances. That is the honest version of the claim.
Will I see other people?
Very few on the northern traverse. You rejoin the main flow only on summit night and on the descent to Mweka.
Can I do it in fewer than nine days?
Shortened variants are sold. They work by cutting out sections of the northern traverse, which removes precisely the acclimatisation that the route exists to provide. If you are going to shorten it, the more coherent choice is a different route altogether.
