Day 13–29 — Climbing Period & Summit Attempts (Manaslu Expedition)
This is the heart of the Manaslu Expedition, where climbers combine acclimatization rotations with actual summit attempts. Starting from Manaslu Base Camp (4,600 m / 15,091 ft), climbers rotate through High Camp I, High Camp II, and Advanced Base Camp, gaining altitude gradually to prepare their bodies for the 8,163-meter summit. These days involve technical climbing across glaciers, icefalls, and exposed ridges, with guidance from experienced Sherpas, ensuring safety and efficiency.
During this period, climbers alternate between climbing higher camps and returning to lower camps to allow for proper acclimatization. When the weather window is suitable, climbers make summit attempts, which involve steep snow and ice sections, fixed ropes, and careful navigation through crevasses. Each summit push is planned meticulously, with oxygen support available for those who need it, and climbers rely on team coordination and high-altitude experience. Along the way, the expedition passes through stunning Himalayan vistas, including Himalchuli, Ngadi Chuli, and Cheo Himal, as well as glacier moraines and snow-covered ridges.
The climbing period also includes rest days, during which climbers recover, hydrate, and perform minor training exercises, ensuring that they remain in peak condition for summit attempts. Spiritual practices, such as prayer ceremonies, are observed at camps, reflecting the local Buddhist culture of the Manaslu region. By the end of this period, climbers either have reached the summit of Manaslu (8,163 m) or have completed their rotations, ready to begin the descent safely back to Base Camp.
