Trip summary

Gasherbrum I, Also known as K5 or the Hidden Peak, it is the eleventh highest mountain in the world. It is located in the Karakoram range in Pakistan and is part of the Gasherbrum massif, a group of peaks that includes Gasherbrum I, II, III, IV, and V. Gasherbrum I, at 8,080 meters (26,510 feet), is considered a challenging climb due to its steep and icy terrain.

The group forms a semicircle around its own glacier, Gasherbrum South. A French expedition led by H. De Segogne made the first attempt in 1936 but failed to ascend beyond Camp V, at an altitude of 6,797 meters. Gasherbrum I was first climbed on July 5, 1958, by Pete Schoening and Andy Kauffman, of an eight-man American expedition led by Nicholas B. Clinch. Richard K. Irvin, Tom Nevison, Tom McCormack, Bob Swift, and Gil Roberts were also part of the team.

Gasherbrum I is the least popular of the eight-thousanders. It is also one of the peaks with the fewest fatalities, but this is probably because only experienced mountaineers venture onto such a remote and hidden mountain as Gasherbrum I. The peak was also the site of the world’s first ascent of an eight-thousander in pure alpine style. This means that the climb starts from the base of the mountain and all the equipment is carried along the way; if bivouacs are needed, they are found on the route. The most common way to ascend the peak is to attempt it via the west face, and all routes here lead to the “Japanese Couloir,” located at the top of the northwest face.

Seven Summit Treks’ Gasherbrum I expedition will begin the third week of June from Islamabad and continue with a flight to Skardu. The elevation gain from base camp to the summit exceeds 3,000 meters. At this point, we will establish three camps to facilitate your ascent and acclimatization. We will rotate frequently between each camp for optimal acclimatization. Base Camp is normally located at 5,000 m (16,404 ft), Camp I at 6,000 m (19,685 ft), Camp II at 6,400 m (20,997 ft), Camp III at 7,200 m (23,622 ft), and the summit at 8,068 m (26,470 ft).

More Information

Base Camp (5000 m/16,404 ft)
Fly to Skardu, travel to Jhola, and trek to base camp, where we will reach an altitude of 5000 m with magnificent views of the Karakoram. After 6 days of trekking, we will arrive at the base camp of Mount Gi. At base camp, our best team of Sherpas will be waiting for us. Seven Summit Treks boasts the best base camp setup. We will spend approximately one month at base camp. Each member will have an individual tent, and dinner will be in shared tents with kitchens, showers, communication, and toilets. Before ascending, we will perform a large ceromancy puja at base camp to wish for good luck and a safe climb.
Camp I (6000 m/19,685 ft)
Once at base camp, our personal climbing Sherpa or team leader will review the basic and advanced training for base camp. For better acclimatization, once the Sherpa team has fixed the rope, you will ascend to Camp I, located at 6,000 m (23,000 ft). This section of the climb involves numerous crevasses and a long, flat route covered in snow. This will take 6 to 7 hours of climbing. We will rotate frequently between Camp I and Base Camp. Up to Camp I, the climbing route is the same as for Camps I and II.
Camp II (6,400 m/20,997 ft)
The climb from Camp I to Camp II consists of flat, snowy sections. In this section, in addition to some crevasses, all climbers will be using the main rope. This section of the climb will take 4 to 5 hours.
Camp III (7200 m/23,622 ft)
The climbing section from Camp II to Camp III is a rocky and icy area. You will climb alongside the “Japanese Couloir.” The climb will take 5 to 6 hours. You will climb with a Sherpa and a fixed rope. It is somewhat risky due to avalanches. During the climb, your personal guide will always be with you. This section will last 5 to 6 hours.
Summit (8080 m/26,510 ft)
The most important day is summit day. It is the main goal of all climbers. It is a day that climbers dream of. The ascent to the summit is not too difficult. It is a dream come true. Therefore, most climbers begin their ascent to the summit at 1:00 AM and hike for approximately 8 to 10 hours, reaching the top around 8:00-10:00 AM. The summit of Mount Gi is breathtaking. You will be captivated by the stunning views of various 8,000-meter peaks and the many beautiful mountains of the Pakistani Himalayas. Later that day, after taking some photos, you will descend to Camp II, or Base Camp, which will take about 6 to 7 hours. The descent from the summit is also a challenging part of this expedition, so safety on the descent is paramount on summit day. Seven Summit Treks will have a climbing Sherpa and a team member accompanying you from Camp IV to summit day and back to Base Camp. The SST guide will carry the oxygen bottles for the team members and themselves. For a safe summit of Mount Gi, SST will always have access to the best weather recommendations, communication, and support from the Base Camp leader. Fixing ropes to reach the summit is the main task of our climbing sherpa, so we greatly admire his ability to fix ropes, open trails and make every effort to get the group to the top of Mount Gi.
