CHO OYU EXPEDITION

A comprehensive briefing covers the full route, the Tibet-side logistics, camp structure, oxygen system management, acclimatization plan, safety protocols, Chinese permit formalities, and weather monitoring strategy. Equipment is confirmed and checked. You receive your Alpinist Climber Expeditions duffel bag, cap, and T-shirt. Any last-minute gear requirements are addressed here in Kathmandu while alternatives are still available.

An early helicopter flight from Kathmandu to Timure on the Nepal–Tibet border. From Timure, a road transfer through the Chinese border formalities and into the Tibetan plateau delivers the team to Gyabrag Base Camp at 5,700m — arriving the same day as departure from Kathmandu. The altitude gain from 1,330m to 5,700m in a single day is significant. Activity on arrival is kept to an absolute minimum. Tents are established, a light meal prepared, and the team rests early.

A full rest day to begin altitude adaptation. The Puja ceremony is conducted in the morning — a traditional Sherpa blessing led by a lama, attended by the full expedition team, with all climbing equipment blessed before use on the mountain. At 5,700m on the Tibetan plateau, with Cho Oyu's northwest ridge visible directly above, the ceremony marks the formal beginning of the climbing phase. The rest of the day is for light acclimatization movement and rest.

An IFMGA guide leads a technical training session at Base Camp covering oxygen system use and mask fitting, crampon technique on the glacier approach, fixed rope management, ascender use, and the protocols for moving efficiently as a team above 7,000 metres. Oxygen regulators and masks are tested on all members. This session ensures the team is fully prepared technically before the first altitude rotation begins.

The first controlled altitude move above Base Camp — ascending to approximately 6,000m on the lower section of the northwest ridge before returning. This rotation confirms equipment function, initiates physiological altitude adaptation above Base Camp, and familiarizes the team with the route conditions above. An early return ensures the acclimatization benefit without unnecessary fatigue ahead of the Camp 1 rotation.

A rest day at Base Camp. The body consolidates its adaptation to 5,700m. The team eats well, rests, hydrates thoroughly, and prepares for the first camp-to-camp move beginning the following morning. Weather forecasts are reviewed and the plan for the Camp 1 ascent confirmed.

The team moves from Base Camp to Camp 1 at 6,400m — ascending the lower northwest ridge on glaciated terrain. The mountain's scale reveals itself more completely with every hundred metres gained. Camp 1 is a well-established position on the ridge. Tents are occupied, a hot meal prepared, and the team rests with Camp 2 and the upper mountain now visible above.

From Camp 1, the team pushes up the ridge toward Camp 2, reaching approximately 6,700m before returning to Camp 1. This move gives the team its first exposure above 6,400m on the Cho Oyu route — the terrain between Camp 1 and Camp 2 is steeper and more demanding, and this controlled push begins altitude adaptation at the next level before the full summit rotation.

A full descent from Camp 1 to Base Camp. The altitude drop from 6,400m to 5,700m allows meaningful physiological recovery — appetite returns, sleep quality improves, and the body restores the energy reserves that the previous two days have drawn on. This descent is a critical part of the acclimatization process, not a concession.

A dedicated recovery day at Base Camp. The team rests, eats generously, and allows the body to fully consolidate the acclimatization gains from the first rotation. Weather forecasts for the upper mountain are reviewed. The second rotation to Camp 2 begins the following morning.

The team returns to Camp 1 at 6,400m — familiar terrain now, climbed with noticeably greater efficiency than the first rotation. The body is better adapted, the route is known, and the focus shifts toward Camp 2 and the upper mountain. The team occupies Camp 1 tents and rests for the push to Camp 2 the following morning.

The team pushes from Camp 1 to Camp 2 at 7,200m — the most significant altitude gain of the acclimatization phase. The terrain between Camp 1 and Camp 2 is sustained and demanding at this altitude. Camp 2 at 7,200m places the team above the vast majority of climbers who have ever been at altitude on this mountain. This is the moment when the scale of an 8,000-metre expedition begins to feel fully real. Hot food and drinks are prepared on arrival. The team rests carefully with the upper mountain now directly within reach.

Full descent from Camp 2 to Base Camp — a significant drop from 7,200m that delivers rapid and substantial physiological recovery. Energy, appetite, and cognitive clarity return quickly at lower altitude. This recovery is the foundation of the summit push. The team rests at Base Camp and prepares for the summit rotation that begins within the high-altitude climbing window.

This 11-day period is managed entirely in the field by Mr. Prakash Sherpa. It encompasses rest and recovery at Base Camp following the acclimatization rotations, a second push to Camp 2 and the first ascent to Camp 3 (7,700m), weather monitoring and summit window assessment, the summit push to Cho Oyu (8,188m), and the descent to Base Camp.

A typical sequence within this window: 2–3 days rest at Base Camp → Ascent Camp 1 → Camp 2 → Camp 3 (7,700m) → Summit push → Descent to Camp 2 → Base Camp. Summit day begins from Camp 3 in the early hours — typically midnight to 2 AM — targeting the summit plateau at 8,188m before midday and descending to Camp 2 or Base Camp the same day. Unlimited supplemental oxygen is in use above Camp 2 for all members and guides throughout this window.

All high camps are cleared and the team descends to Gyabrag Base Camp for the final time. Base Camp is broken down — tents struck, equipment packed, and the site left clean in accordance with the expedition's environmental management standards. Arriving at Base Camp with the summit of the world's sixth highest mountain behind you marks one of the most significant moments of the expedition.

The team departs Gyabrag Base Camp by road for the drive back through Tibet to the Timure border crossing. The road descends steadily from the plateau, and the dramatic altitude drop — from 5,700m to 1,400m — is a physical and psychological transition that marks the end of the high-altitude phase. Overnight at a local guesthouse near Timure.

A helicopter returns the team from Timure to Kathmandu — the same corridor used on arrival, now crossed in the opposite direction with the summit of the world's sixth highest mountain accomplished. The flight arrives in Kathmandu in the late morning. The team transfers to the 4-star hotel for the final days before departure.

A free day in Kathmandu for rest, recovery, and exploration. Thamel, the UNESCO heritage temples, Boudhanath Stupa, and the restaurants of the old city are all accessible. A farewell dinner in the evening is a proper celebration of 30 days, a 8,188-metre summit, and everything it took to reach it.

Private airport transfer for your outbound flight. The Cho Oyu Expedition concludes — 30 days from Kathmandu to the summit of the world's sixth highest mountain and back.
