Chogolisa I (7668 m) is a remote and highly glaciated peak in the Karakoram of northern Pakistan, rising above the Baltoro Glacier near the famous Concordia basin. It is one of the most striking mountains in the region, with a broad, elegant profile and severe weather that keeps it far less visited than nearby giants such as K2 and Broad Peak.
The mountain is known for its technical climbing conditions, avalanche exposure, and long approach through high-altitude glacier terrain. Because of its remoteness and objective hazards, Chogolisa I attracts experienced mountaineers rather than casual trekkers, while the surrounding area remains popular with trekkers heading to Concordia and the Baltoro region.
Access usually begins from Skardu, followed by a drive to Askole and a multi-day trek over the Baltoro Glacier. Climbers typically rely on local support teams, porters, and licensed expedition operators. The mountain offers a classic high-Karakoram experience: dramatic scenery, thin air, and a demanding alpine environment.

There is no standard trekking route to the summit of Chogolisa I, but trekkers can view the mountain from the Baltoro Glacier approach to Concordia. The classic trek starts in Askole and follows a long glacial corridor past Jhola, Paiju, and Urdukas. It is a strenuous high-altitude route with river crossings, moraine walking, and camping on rough glacier terrain. The reward is close-up scenery of some of the highest peaks on Earth.
Chogolisa I is climbed by very few teams, and route information is limited compared with major commercial peaks. The most logical lines are on the glacier-facing slopes and ridges above the Baltoro Glacier, but these are exposed to crevasses, seracs, and avalanche danger. Climbers should expect a long expedition-style ascent with advanced glacier travel, fixed rope work, and high-camp logistics. Conditions can change quickly, making route choice highly dependent on weather and snow stability.
The nearest major populated hub is Skardu, the main gateway for expeditions in the Karakoram. From there, teams usually travel by jeep to Askole, the last village on the route and the usual starting point for the trek. Reaching Skardu is possible by domestic flight from Islamabad or by road via the Karakoram Highway. From Askole, access continues on foot through the Baltoro valley toward Concordia.
Climbing in Pakistan requires official permits, and foreign teams usually arrange them through licensed operators. Reliable agencies with strong reputations in the region include Adventure Pakistan, Jasmine Tours, Baltistan Tours, and Karakoram Expeditions. Prices vary widely by route, group size, and support level; a full expedition package for a remote 7000+ m peak can range from about USD 8,000 to USD 25,000+ per climber. Local guides and porters are essential for logistics and safety.
The best climbing window for Chogolisa I is usually from late June to early September, when the weather is relatively more stable and access routes are open. Even in this period, the mountain remains cold, windy, and prone to sudden storms. Earlier in the season, snow conditions may be heavier; later in the season, crevasses and unstable ice can become more problematic. Teams should plan for flexible schedules and extra acclimatization days.
Expeditions to Chogolisa I require full high-altitude mountaineering gear: insulated boots, crampons, ice axe, harness, helmet, ropes, ascenders, carabiners, and avalanche safety equipment. For glacier travel, crevasse rescue tools are essential. Camp gear should include a four-season tent, sleeping bag rated for extreme cold, stove, fuel, and layered clothing for subzero conditions. Oxygen is not always used on 7000 m peaks, but teams may consider it depending on route, weather, and acclimatization strategy.
Plan extra days for weather delays, road closures, and acclimatization. Carry cash in Pakistan Rupees for local expenses, and confirm all transport in advance, especially jeep transfers to Askole. Respect local customs in Baltistan, and hire experienced staff familiar with glacier conditions. Mobile coverage is limited or absent on much of the approach, so satellite communication is useful. Because the route is remote, medical evacuation can be slow, making conservative decision-making important.
Chogolisa I is often overshadowed by nearby giants, yet it is one of the most beautiful peaks in the Baltoro region. The mountain has a dramatic, broad summit profile that stands out from the sharper spires around it. It lies close to the legendary Concordia viewpoint, where several major glaciers meet. Despite its size and prominence, it has seen very few ascents, which adds to its reputation as a serious and elusive objective.
Is Chogolisa I suitable for beginners? No. It is a remote, technical high-altitude peak that requires strong glacier and expedition experience.
Can I trek to see the mountain without climbing it? Yes. Trekkers on the Baltoro Glacier route can view it from the approach to Concordia.
Do I need a guide? For a climb, yes. Local guides and support staff are strongly recommended and usually required for logistics.
How long does the approach take? The trek from Askole to the high glacier area typically takes several days, depending on pace and conditions.
