Route, acclimatisation and permit notes for Langsisa Ri from the Nepal Side side, plus practical safety advice.
Stands at 6,427 m (21,085 ft) in the Langtang Himal range.
Guards the headwaters of the Langtang Khola glacier network.
Remote Valley: The approach passes Kyanjin Gompa and extends into the uninhabited Langsisa Kharka pastures.
Involves setting up base camp at Langsisa Kharka, followed by high camps on ice fields.
The standard season on Langsisa Ri is Spring & Autumn (Mar–May / Sep–Nov). Expedition Logistics: Requires full tented support beyond Kyanjin Gompa.
Approaches to Langsisa Ri begin from Nepal Side in Rasuwa District, where the main objective is the South Ridge. Confirm current permit, insurance, and national park requirements before departure.
Plan for road travel to the Nepal Side trailhead, then several days of walking before you reach the foot of Langsisa Ri. Gain height gradually, take a rest day before moving to high camp, and keep a spare weather day in reserve during Spring & Autumn.
Summit day on a 6,427 m objective is long, so start early and set a clear turn-around time. If the South Ridge is crowded or the snow is unstable, waiting a day is almost always better than pushing on.
