At a glance

Trip overview

Cho Oyu, known as the Turquoise Goddess, stands at 8,188 m on the border between Nepal and Tibet. As the sixth highest mountain on Earth and situated roughly 20 km from Mount Everest, it offers a rigorous objective for climbers stepping up to the 8,000-metre tier. Our expedition follows the conventional Northwest Ridge route, presenting a more approachable profile than neighbouring giants while still demanding respect for high-altitude hazards.

This 47-day itinerary balances thorough acclimatisation through Tibet with structured rotations on the mountain. We handle every operational detail, from permits and logistics in Kathmandu to transport across the Tibetan plateau via Lhasa and Shigatse, establishing a reliable support structure up to Advance Base Camp.

We design this climb for mountaineers who have solid experience on 6,000-metre and 7,000-metre peaks, comfortable with crampon use, fixed-line travel, and extended periods operating in low-oxygen environments. Our lead guides bring extensive hands-on experience on Cho Oyu, maintaining strict safety margins and managing every controllable factor to support your summit attempt.

Before you go

Good to know

Fitness expectations

This expedition requires advanced mountaineering competence and a high baseline of cardiovascular endurance. You should have prior summit experience on 6,000 m and 7,000 m peaks and be comfortable using crampons, ascenders, and ice axes on steep snow and ice.

Altitude & acclimatisation

Operating up to 8,188 m exposes the body to severe hypoxic stress. Our itinerary incorporates gradual ascent profiles through Tibet, scheduled rest days in Old Tingri, and systematic rotational climbs to higher camps before any summit attempt.

Logistics & permits

All logistics across Tibet, including group visas, travel permits, transport, and base camp infrastructure, require extensive advance planning. We manage these administrative requirements through our established operating networks.

Weather considerations

Himalayan weather is volatile, particularly above 7,000 m where jet stream winds dominate. We monitor forecasting data continuously and maintain flexibility in our schedule to capitalize on safe summit windows.
