K2 expedition, south-east ridge
Overview
A 58-day expedition to K2 at 8,611 m by the Abruzzi Spur, the standard route from the Godwin-Austen glacier. Maximum six climbers, one high-altitude guide per two, bottled oxygen above 8,000 m. K2 is the hardest of the fourteen eight-thousanders to climb and the one with the worst summit-day record, and we sell it on that basis rather than around it.
Why the trip is 58 days long
Because K2 does not give you a summit window on demand. The expedition breaks into four parts: the approach up the Baltoro to base camp at 5,150 m, a rotation cycle building acclimatisation through Camps 1 to 3, a waiting period at base camp for a weather window, and the summit push itself. The waiting is not padding — in a bad year it is the whole second half of the trip, and an itinerary that does not budget for it is an itinerary that pushes people into weather they should have sat out.
The route
The Abruzzi Spur rises from the Godwin-Austen directly to the south-east ridge. Camp 1 at around 6,100 m sits above the first rock. House’s Chimney above it, then Camp 2 at roughly 6,700 m. The Black Pyramid — the hardest sustained rock and mixed ground on the route — leads to the shoulder and Camp 3 near 7,300 m. Camp 4 goes on the shoulder at about 7,900 m, and the summit day crosses the Bottleneck beneath the hanging serac, traverses left under the ice, and climbs the summit snowfields.
The Bottleneck is the crux and the reason for the mountain’s reputation. It is objectively dangerous ground, exposed to a serac that cannot be protected against, and the only mitigation is being there briefly and early.
Who we take
Previous 8,000 m summit experience, or a strong 7,000 m record with technical mixed ground and references we can call. We ask for a climbing history at enquiry, not a declaration at base camp. We would rather lose a booking than carry someone through the Black Pyramid who should not be on it.
Turn-back criteria, written down before you leave
A summit time, a weather threshold, a bottled-oxygen reserve and a client-condition standard, all agreed in writing before the push and all held by the lead guide. On this mountain the decision to descend is the skill, and we do not want it negotiated at 8,200 m by people who did not know the rules.
What is inside the price
Peak royalty and liaison officer, permits and park fees, the trekking visa file, all transport from Islamabad, the Baltoro approach with porter crews under our published charter, base camp with cook and full mess through the whole 58 days, rope and hardware on the route, bottled oxygen and masks, a high-altitude guide per two climbers, satellite communications and daily weather forecasting, and a written evacuation plan. Insurance covering helicopter evacuation above 6,000 m is mandatory and verified before departure.

Fixed departures
These prices are per person on a fixed departure, and they are the price — we do not discount a published figure. Deposit is 25%; the payment schedule and cancellation terms are published and sent with every quote. For your own dates, see the private pricing below.
Private departures and group pricing
Your party, your dates. The per-person figure falls as the party grows, because the guides, the vehicles and the camp cost the same split more ways. Everything in the inclusions list applies, and the safety standard is the one published above.
| Party size | Price per person | Notes |
|---|---|---|
| 2 | [PRICE] | Private guide and vehicle for the two of you |
| 3 – 4 | [PRICE] | |
| 5 – 8 | [PRICE] | Second guide joins at six |
| 9 – 12 | [PRICE] | By arrangement, season permitting |
Deposit is 25% of the trip price. The payment schedule and the cancellation terms are published and sent with every quote, before you pay anything.

Safety, evacuation and insurance
Helicopter rescue in the Karakoram is not guaranteed. Weather, altitude, daylight and clearance all decide whether a helicopter flies, so every stage carries a named drive-out or walk-out plan. Your insurance must cover helicopter evacuation and repatriation to the maximum altitude on your itinerary, and we verify the certificate before the trip starts.
A graded medical kit sized to the trip, oxygen, a portable altitude chamber, a satellite phone and a messenger, and a wilderness first responder in the crew.
The lead guide’s decision to turn back is final. Not a guest, not an agent, not this office — whatever has been paid.
Getting there
Islamabad
Met inside the terminal by a member of our team, not a driver with a sign outside it. Briefing the same evening, local SIM and cash sorted.
Islamabad to Skardu
A short flight that is weather-dependent, or a long road that is not. We build a buffer day either way and quote both.
On the ground
Our own 4x4s and our own drivers from Skardu onward.
Questions people actually ask
Why is K2 harder than Everest?
Sustained technical ground from low on the mountain, no easy descent, a shorter and less reliable weather window, and the Bottleneck — a traverse under a hanging serac that nobody can make safe. None of that is reflected in the altitude figure.
What experience do I need before you will take me?
Previous experience at the altitude band below this one, and we check it rather than take your word for it. If the experience is not there we say no. That is not a sales tactic — it is the difference between an expedition and an accident.
How long will I actually be on the mountain?
Most of the trip. The approach and the walk out are a fortnight between them; the rest is rotations, waiting for weather, and one summit push if the mountain gives you one.
What are the chances of summiting?
Weather decides most of it and we do not publish a success rate, because we have not run enough departures on this peak to quote one honestly. Anybody quoting you a percentage is quoting somebody else's season.
Who decides when to go up?
The lead guide, on the forecast and on what the mountain is doing. That decision is final and cannot be overruled by a climber, an agent or this office. It is written into your contract.
What happens if I have to go down early?
Someone qualified goes down with you — that is what the guide ratio is for. The expedition continues. There is no refund for an unused portion, which is in the payment and refunds page before you pay.
Is there a summit bonus?
If you choose to pay one it is yours to arrange and it is not in our price. We pay our crew their published wage whether or not anybody summits, and we would rather that were not confused with a bonus.
What communications are there?
Satellite phone at base camp, a messenger with the lead guide, and a daily scheduled call to this office. Your nominated contact at home gets an update every evening.
If this one is not quite right
The commonest reason a trip is wrong is that it is too hard or too easy, not that it is in the wrong place.
