Gasherbrum I, 8,080 m, the Hidden Peak beyond Concordia. A remote, serious 8,000 m objective, run with Skardu and Askole logistics.
A booking deposit applies. See our booking terms & cancellation policy.
Gasherbrum I, 8,080 m, is the highest summit of the Gasherbrum group and one of the more serious 8,000 m objectives in Pakistan. It sits beyond Concordia in the upper Baltoro, far enough from the trailhead that the expedition has to be planned carefully from the first porter load in Askole to the last weather call at base camp.
Most teams use three high camps above base camp, with at least one acclimatisation rotation before committing to a summit window. The best season is the main Karakoram summer, usually late June through July into early August, and summit plans stay flexible because snow, wind and avalanche risk set the pace.
Experienced high-altitude climbers who want a serious Karakoram 8,000 m expedition. Honest about fitness, patient with weather, able to work with a team through delays and uncomfortable days at altitude. The summit is the goal; returning healthy as a team is the standard.
5 July 1958 — First ascent. Andrew Kauffman and Peter Schoening reached the summit by the southeast ridge, on the American expedition led by Nicholas Clinch. It remains the only 8,000-metre peak first climbed by an American team.
9 March 2012 — First winter ascent. Adam Bielecki and Janusz Gołąb of the Polish winter expedition made the first winter ascent.
Airport welcome, hotel transfer and a first briefing on the route, weather and logistics. The rest of the day is for recovery after the journey.

5,150 mThis block is held for acclimatisation rotations, rest, load carries, the summit attempt and the descent. The usual plan uses Camps 1, 2 and 3 above base camp; exact timing depends on route condition and weather.

DepartureGasherbrum I is generally the more demanding of the two: higher, more serious in character and less forgiving in poor conditions.
Summer, especially July and early August. We usually plan arrival in Pakistan in late June or early July.
Strongly recommended. At minimum you should have climbed a 7,000 m peak or a serious alpine route, and be comfortable with expedition camping and fixed lines when tired.
Oxygen can be added to the final proposal. We confirm bottle count, mask, regulator and carrying support before booking.
The fair price depends on group size, dates, porter allowance, oxygen choice and the level of high-altitude support. We prefer to understand your team first and then send a clear written proposal.
Yes. We handle the mountaineering permit, peak royalty, environment fees, liaison officer coordination and the official briefing and debriefing. We need your passport copies, visa details and insurance documents well before arrival.
