Our 35-day technical expedition to 7129 m Baruntse via the Hinku Valley and Mera La.
At a glance
Trip overview
Our Baruntse Expedition is a technical high-altitude undertaking targeting the 7129 m summit situated between the Hinku, Barun, and Imja glacier systems. We designed this 35-day itinerary for mountaineers who have prior experience at the 6000 m level and seek a structured progression into the greater Himalayan peaks. The approach takes us through the remote Hinku Valley, offering an effective natural acclimatisation profile via Mera La before we establish our base camp.
We lead this route with our experienced Sherpa climbing teams, utilising full camping infrastructure at base camp and advance base camp while taking meals in teahouses during the initial trekking phases. The terrain involves glacier travel, fixed ropes on steep snow and ice ribs, and high-camp rotations. Climbers must be comfortable with crampon use, ascents on exposed ridges, and self-care in sub-zero alpine conditions.
The return route traverses the demanding Amphu Latsa pass into Chukung, descending the main Khumbu trail via Namche Bazaar before our final flight from Lukla to Kathmandu. This multi-valley traverse demands robust physical fitness, mental resilience, and rigorous adherence to our lead guide's safety protocols on the mountain.
