Crater Camp

Crater Camp is not a route

This is the first thing to be clear about, because almost every quote that includes Crater Camp presents it as though it were one. It is not. It is a single extra night spent inside Kibo's summit caldera, added onto the end of an existing route, and TANAPA lists it as a separately permitted activity rather than a trail.

On a normal Kilimanjaro itinerary, summit night takes you from a high camp to the crater rim, round to Uhuru Peak at 5,895 metres, and then immediately back down several thousand feet to sleep somewhere much lower. With a crater night, that sequence is broken: instead of descending, you drop from the rim into the caldera, camp there, and climb the short remaining distance to Uhuru the following morning.

So what you are buying is not more mountain. It is a night at almost the height of the summit, and a summit morning that starts an hour's walk away instead of seven hours away.

What is down there

Kibo is a dormant volcano, not an extinct one, and its crater is the reason this is worth doing at all. Inside the outer rim sits an inner crater, and inside that the ash pit — the volcanic core, which TANAPA lists among the park's attractions alongside the summit itself.

The other reason is the ice. The Furtwängler Glacier stands on the crater floor, and TANAPA describes the formations here as bench-shaped glaciers found nowhere else on earth. Walking up to a wall of ice at that altitude, on a flat plain of ash, with the crater rim all around you, is unlike anything else on the mountain, and it is the thing everybody who has done it talks about.

It is also diminishing. A 2009 paper in PNAS reported that 85 per cent of the ice present on Kilimanjaro in 1912 had gone, and that the Furtwängler Glacier had thinned by roughly half at its drill site between 2000 and 2009. In April 2026, KINAPA's ecology officer told Tanzanian reporters that GIS analysis showed ice cover increasing again, which he attributed to conservation work. Those accounts are hard to reconcile. What is not in question is that the ice on the crater floor is a remnant of something much larger.

What sleeping that high does to you

Here is the honest version, and it is the reason this page exists separately from the route guides.

Descent is the treatment for altitude illness. Every other night on Kilimanjaro, if you get into trouble, the answer is to lose height and there is a great deal of height available immediately below you. In the crater, you are within a few hundred metres of the highest point in Africa, you are at the top of a large mountain, and the first part of any evacuation is upwards, over the rim, before it can start going down.

The research that bears most directly on this band is a ten-year retrospective study of 917 Kilimanjaro trekkers, published in 2014, which found that taking dexamethasone before ascending above 5,790 metres reduced the probability of showing altitude symptoms at that altitude. That is a study about medication, not about camping, and it should be read as a marker of how hostile that altitude is rather than as a green light — the same study found that two extra days on the mountain did not reduce how common symptoms were.

Sleeping is where altitude illness usually declares itself. Breathing slows and becomes irregular in sleep, oxygen saturation drops further than it does when you are awake, and the two serious forms of altitude illness — fluid on the lungs, and swelling of the brain — most often develop overnight. A crater night takes the most dangerous few hours of the whole climb and moves them to the highest point at which they could possibly happen.

People do this safely and routinely. They do it having spent a week or more acclimatising first. The general physiology is set out in the main Kilimanjaro climbing guide.

Which itineraries carry it

A crater night is added to long routes, because the acclimatisation it requires can only come from days already spent high. In practice it appears on:

• Lemosho itineraries of eight days or more, which is the most common pairing;
• the Northern Circuit, which provides more nights at altitude than anything else on the mountain;
• Machame at its longer lengths;
• itineraries that reach the caldera by the Western Breach, which enters from the western rim rather than climbing to it from the south-east — a route with a rockfall history and its own page, and one that is not always open.

A crater night bolted onto a short itinerary is the combination to refuse. If an operator proposes one on a six-day trip, that is a question worth asking directly. The published fee for a night that high, and how the rest of the Kilimanjaro fee stack is built, is set out in what a climb costs before an operator adds anything.

The permit and the rules

Crater camping is a special-product activity on TANAPA's own list, permitted and administered separately from your climbing permit. Your operator arranges it; it is not something that can be decided on the mountain because the weather looks good.

The ordinary park rules still apply and matter more here than anywhere: camp only at the designated site, carry out everything you carry in, and leave by the gate on your permit. Waste has nowhere to go at that altitude and nothing breaks down.

Two practical points. Your crew comes with you, which means porters sleeping up there too — the questions about their equipment and shelter in the main guide apply with more force here than anywhere on the mountain. And equipment that copes at Barafu can fail in the crater: water freezes, batteries die, and a sleeping bag that was adequate lower down may not be.

Who it suits

It suits climbers on a long itinerary who have acclimatised well, know how their own body behaves at altitude, and want the crater floor and the glaciers rather than a photograph at the sign. It suits people for whom the ordinary summit night — seven hours of scree in the dark — is the part they most want to avoid, since a crater night replaces it with a short morning walk.

Do not take it if this is your first time above 4,000 metres; if you have felt rough at any point on the ascent; if you are on a short itinerary; or if anyone in your group has a medical history that makes a slow evacuation a serious concern. The honest position is that this is an optional extra that increases both the reward and the risk, and the increase in risk is not marginal.
