Cho Oyu Expedition - 8201 M - 35 Days

Upon arrival at Tribhuvan International Airport, you are received by the Expedition Himalaya team and transferred to a 4-star  hotel in the quiet Lazimpat area. The rest of the day is free to rest and recover from international travel. The hotel offers a comfortable environment before the expedition begins spacious rooms for rest and recovery.

These two days are dedicated to expedition preparation. Climbing permits, Tibet Travel Permit, Chinese Group Visa documentation, and final logistics are completed.

You meet the Expedition Leader, climbing Sherpas, and support team for detailed briefings. Equipment checks are carried out thoroughly. High altitude boots are tested with crampons, oxygen masks are fitted, regulators are inspected, and all climbing gear is verified.

One evening includes a traditional Nepali welcome dinner with cultural performances, offering a relaxed and meaningful start to the expedition.

A spectacular trans-Himalayan flight brings you into Lhasa. Upon arrival, you immediately notice the thinner air. The day is kept light with short walks around the hotel to begin gradual acclimatization.

Today is dedicated to acclimatization. A gentle sightseeing walk is arranged to assist adaptation to altitude. You may visit cultural landmarks such as the Potala Palace area and surrounding monasteries, keeping physical activity light and controlled. Hydration and nutrition are emphasized.

The overland journey across the Tibetan Plateau begins. The drive takes approximately six to seven hours, gradually increasing altitude. The landscape becomes expansive and dramatic, with snow peaks visible in the distance.

Today we continue toward Tingri. As the elevation increases, views of the Himalayan range become more prominent. Mild altitude symptoms may appear, which is normal at this stage.

A short acclimatization hike to approximately 4,800 m / 15,748 ft is conducted before returning to Tingri. This climb-high, sleep-low strategy improves adaptation before reaching Base Camp. The afternoon is reserved for rest.

Drive to the Chinese Base Camp, the official starting point of the expedition. The camp is set on a wide open plain beneath the mountain. Here, expedition infrastructure includes dining tents, sleeping tents, communication equipment. 

Today is reserved for acclimatization and final preparations before moving higher. At 4,800 meters, the body continues adjusting to thinner air, so light walks around camp are encouraged while avoiding overexertion. Oxygen saturation levels are monitored regularly.

Climbing equipment is sorted and prepared for yak transport to Advanced Base Camp. High-altitude tents, personal summit gear, and oxygen systems (if applicable) are checked carefully. A short briefing reviews the route and upcoming movement to ABC.

The climbing phase begins with the gradual move to Advanced Base Camp, which becomes our operational home for the next three weeks. From here, the Northwest Ridge rises in broad snow slopes and glaciated terrain averaging 25–35 degrees. Ropes are fixed on steeper sections to ensure safety and efficiency. While technically moderate compared to other 8000-meter routes, the altitude above 7,000 meters is fully demanding and requires disciplined pacing.

The acclimatization strategy follows a structured rotation system. The first rotation reaches Camp I at approximately 6,400 m / 20,997 ft before returning to Advanced Base Camp to sleep lower. The second rotation progresses to Camp II at around 7,100 m / 23,294 ft, where climbers spend time adapting to the 7,000-meter zone before descending for extended recovery at ABC.

Once a stable weather window is confirmed, the summit rotation begins. The ascent moves steadily from Advanced Base Camp through Camp I and Camp II, and if required, Camp III. Oxygen-supported climbers typically begin supplemental oxygen at Camp II or Camp III to conserve strength for summit day.

Summit day starts before dawn, following steady snow slopes to a broad summit ridge. Reaching the summit of Cho Oyu at 8,201 m / 26,906 ft marks a significant high-altitude achievement, but safe descent remains the priority. The team descends methodically through the camps and returns to Advanced Base Camp for recovery.

Throughout this period, all decisions are conservative and guided by weather forecasts, snow conditions, and the health of each climber.

We begin the gradual descent across the moraine and glacial terrain back to Chinese Base Camp. The trek takes several hours, and the drop in altitude is immediately noticeable as breathing becomes easier and energy slowly returns.

Upon reaching Chinese Base Camp, vehicles are arranged for the drive back to Tingri. The transition from expedition camp life to basic town accommodation brings a sense of comfort after weeks at altitude.

Today we drive toward Kyirong (Gyirong), descending from the high Tibetan Plateau to approximately 2,700 m / 8,858 ft. The long drive follows wide valleys and dramatic mountain landscapes.

As altitude decreases, oxygen levels improve significantly and recovery accelerates. Kerung offers a more comfortable climate and better sleep after extended time at extreme altitude.

After completing border formalities, we re-enter Nepal and continue the scenic drive toward Kathmandu. The landscape shifts from the dry plateau of Tibet to the greener hills and river valleys of Nepal.

Upon arrival in Kathmandu, transfer to your hotel and enjoy a well-deserved rest after the expedition journey.

A full rest day in Kathmandu to relax and recover. You may explore the city, visit local markets, or simply enjoy the comfort of the hotel. In the evening, a farewell dinner is arranged to celebrate the successful completion of the Cho Oyu expedition.

On the final day, the team will assist you with your departure arrangements. You’ll be transferred to Tribhuvan International Airport for your flight home, leaving with unforgettable memories of your Cho Oyu expedition.
