Crater Camp: Sleeping at 5,729m Inside Kilimanjaro's Caldera

Crater Camp is the highest campsite on Kilimanjaro — and one of the highest on Earth. At 5,729 metres (18,795 feet), it sits inside the volcanic caldera of Kibo, just 166 metres below Uhuru Peak. Sleeping in the crater is a rare, otherworldly experience reserved for a small number of climbers each year — fewer than 500 out of the 35,000+ who attempt Kilimanjaro annually. In our expeditions, Crater Camp has consistently been the most unforgettable night our climbers have ever spent on a mountain. This guide explains what it takes to get there and what you will experience when you do.

What Is Crater Camp?

Crater Camp occupies a flat section of volcanic ash inside the Kibo caldera, between the Furtwängler Glacier and the Reusch Crater. The campsite sits at approximately 5,729m on the caldera floor, surrounded by the ancient walls of the volcanic rim. To the south, the remaining fragments of the Southern Icefield tower overhead. To the north, the Reusch Crater's ash pit releases faint wisps of sulphurous gas — a reminder that Kilimanjaro is dormant, not extinct.

The campsite itself is stark. There is no vegetation, no wildlife, no colour beyond shades of grey, black, and white. The ground is volcanic ash and scree. The air contains roughly 48% of the oxygen available at sea level. It is, by any measure, one of the most extreme camping locations available to non-technical mountaineers anywhere in the world.

Why Camp in the Crater?

The reasons are experiential, not logistical:

• Walk-up summit at dawnInstead of the gruelling midnight summit push from Barafu (4,673m), Crater Camp climbers wake at dawn and walk just 166 vertical metres to
  Uhuru Peak. The summit push takes 30-60 minutes instead of 6-8 hours. You arrive fresh, rested, and able to fully absorb the moment.
• Furtwängler Glacier up closeCamp sits adjacent to the Furtwängler Glacier — the iconic ice formation in the centre of the crater. As these
  glaciers disappear, the opportunity to camp beside them becomes increasingly rare.
• Sunrise and sunset from 5,729mWatching the sun rise and set from inside the caldera is an experience available nowhere else on the mountain. The play of light on the ice and volcanic walls is extraordinary.
• Bragging rightsSleeping at 5,729m on Kilimanjaro is a genuine achievement that separates a Crater Camp expedition from a standard Kilimanjaro climb.

The Itinerary: How to Get There

Crater Camp is not a separate route — it is an extension added to an existing route. The most common base routes are the Lemosho or Machame, extended by one day to include the crater overnight.

Typical 8-Day Lemosho + Crater Camp Itinerary

Day	Stage	Altitude	Hours
1	Londorossi Gate → Big Tree Camp	2,100m → 2,780m	3-4h
2	Big Tree Camp → Shira 2 Camp	2,780m → 3,840m	5-6h
3	Shira 2 → Lava Tower → Barranco Camp	3,840m → 4,630m → 3,960m	6-7h
4	Barranco Camp → Karanga Camp	3,960m → 3,995m	4-5h
5	Karanga Camp → Barafu Camp	3,995m → 4,673m	3-4h
6	Barafu → Stella Point → Crater Camp	4,673m → 5,756m → 5,729m	6-8h
7	Crater Camp → Uhuru Peak → Millennium Camp	5,729m → 5,895m → 3,100m	8-10h
8	Millennium Camp → Mweka Gate	3,100m → 1,640m	4-5h

The critical day is Day 6: you ascend from Barafu Camp to Stella Point on the crater rim (the same route as a standard summit push), but instead of continuing to Uhuru Peak, you descend into the crater and make camp. Day 7, you walk to Uhuru Peak at sunrise, then descend all the way to Millennium Camp.

Physical Requirements

Crater Camp demands more from your body than a standard Kilimanjaro climb. You are spending a night at extreme altitude — 5,729m — where acclimatization is critical and sleep is difficult. Requirements:

• Prior altitude experienceWhile not strictly mandatory, we strongly recommend that Crater Camp climbers have previous experience above 4,000m. This could be a prior Kilimanjaro climb, Mount Kenya, Mount Meru, or high-altitude trekking in the Himalayas or Andes.
• Excellent fitnessYou need the endurance to ascend from Barafu to the crater rim (same as a summit push), then descend into the crater, all while carrying the knowledge that you will spend the night at extreme altitude. A thorough
  training plan is essential.
• Strong acclimatizationThe 8-day minimum itinerary provides adequate acclimatization for most climbers, but you must be acclimatizing well throughout the trek. If you are showing significant altitude sickness symptoms at Barafu, your guide will advise against the crater extension.
• Mental resilienceSleep at 5,729m is minimal. The cold is extreme (-15°C to -25°C). The air is thin. You need to be comfortable with discomfort.

What to Expect at Crater Camp

The Environment

Crater Camp is lunar. The ground is grey-black volcanic ash. The Furtwängler Glacier rises like a blue-white wall nearby. The caldera walls encircle you on all sides, blocking the wind but trapping the cold. Sound carries strangely in the thin air — voices seem both close and distant. At night, the stars are extraordinary — you are above most of the atmosphere, and the Milky Way arcs overhead with an intensity impossible at lower altitudes.

Temperature

Expect nighttime temperatures between -15°C and -25°C (5°F to -13°F). This is significantly colder than Barafu Camp due to the higher altitude and the caldera's cold-trapping geography. A sleeping bag rated to -20°C or lower is essential. Your gear must be summit-grade.

Sleeping

Genuine sleep at 5,729m is rare. Most climbers doze intermittently, waking frequently to breathe more deeply. This is normal — your body is working hard to oxygenate at half the sea-level oxygen concentration. The short summit walk the next morning means that imperfect sleep is far less consequential than on a standard summit night, where you need energy for a 6-8 hour push.

Water

There is no water source at Crater Camp. All water must be carried up by your porter team or melted from ice (when permitted by KINAPA). Hydration is critical at this altitude — dehydration accelerates altitude sickness. Ensure your team carries adequate water for cooking, drinking, and bottles.

Cost

Crater Camp adds approximately $400-600 to the cost of a standard Kilimanjaro climb. The premium covers the additional camping fees, extra porter wages for carrying gear to extreme altitude, and the specialized equipment required. See our pricing page for current rates.

Frequently Asked Questions

Is Crater Camp safe?

Yes, when properly managed. The risks are altitude-related: acute mountain sickness (AMS), high-altitude pulmonary edema (HAPE), and high-altitude cerebral edema (HACE). Our guides carry pulse oximeters, supplemental oxygen, and Gamow bags, and are trained in high-altitude emergency protocols. The key safeguard is thorough acclimatization — if you are not acclimatizing well, your guide will recommend skipping the crater extension and summiting via the standard route instead. Safety is never compromised.

How many people camp in the crater each year?

Fewer than 500. KINAPA limits the number of groups that can camp in the crater at any given time, and the logistical demands of carrying full camping equipment to 5,729m mean that only a small number of operators offer this option.

Can I add Crater Camp to any route?

In theory, yes — any route that summits via Stella Point can be extended to include a crater night. In practice, the Lemosho (8-9 days) and Northern Circuit (9-10 days) are the best base routes because they provide the strongest acclimatization before the crater night.

Do I need special gear for Crater Camp?

Your standard Kilimanjaro gear is sufficient, but your sleeping bag must be rated to at least -20°C. We also recommend an insulated sleeping pad with an R-value of 5+, chemical hand warmers, a balaclava, and expedition-weight base layers. Your feet will get cold — bring the warmest socks you own.

What about the glacier — will it still be there?

The Furtwängler Glacier is retreating rapidly. Scientists estimate it may disappear entirely within 10-20 years. If camping beside one of Kilimanjaro's last remaining glaciers is important to you, sooner is better than later.

Can beginners do Crater Camp?

We generally advise against it for first-time high-altitude trekkers. The extreme altitude of the overnight stay adds significant physiological stress. If you are determined, choose a 9-day itinerary for maximum acclimatization and discuss your fitness level and altitude history with our team before booking.
