Cho-oyu Expedition

Imagine standing at 8,188 meters (26,906 ft)on the roof of Tibet. The view stretches endlessly in every direction through the Himalayas. To the east, the mighty Everest is only 30 kilometers away. To the north, the Tibetan plateau stretches as far as the eye can see. And above it all, the blue sky shines through the Karakorum range. That is Cho Oyu. The Turquoise Goddess. The sixth highest mountain on Earth. And the doorway to 8,000-meter(26,247 ft) climbing as nowhere else.

Cho Oyu is said to be the easiest of the fourteen eight-thousanders. But when it comes to climbs this high, there is nothing easy about it. But Cho Oyu does promise something unique: a real 8,000-meter (26,247 ft) climb experience on the mountain with the highest success rate and the lowest objective danger at this height. It requires good preparation, patience, and a serious approach to high-altitude climbs. 

The Cho Oyu Expedition 2027 with AltiPro Adventures is your doorway to this journey. If your target is the summit of an 8,000er, then the journey starts here. And for many climbers, this is the mountain they talk about forever.

The Turquoise Goddess is calling. Are you ready to rise?

Overview of Cho-Oyu Expedition 2027

Cho Oyu (8,188m / 26,864ft) means “Turquoise Goddess” in Tibetan. It is the sixth highest mountain in the world and is located 20km to the west of Mount Everest on the border between Nepal and Tibet. Cho Oyu was climbed for the first time in 1954 by an Austrian expedition without supplemental oxygen. It is also famous in climbing history as it was the first 8,000m peak climbed in autumn. The route taken by climbers is via the Northwest Ridge and is famous for its accessibility and high success rate. The route culminates at a large summit plateau with arguably one of the finest views in the Himalayas, encompassing Everest, Lhotse, and all of the other giant peaks of the Mahalangur Himal.

Cho Oyu Expedition 2027 is an Autumn Climbing Package for 49 days with full board, starting from Kathmandu and traveling overland to Tibet via the beautiful Tibetan plateau. The maximum number of climbers in this group will be 12, and there will be a guaranteed 1:1 Climbing Sherpa ratio for every climber. AltiPro provides high-level support for climbing this famous 8,000m peak. It is considered to be the best 8,000m peak for experienced climbers, with three planned rotations for acclimatization, Advanced Base Camp facilities, and weather forecasting for maximum safety and success on the summit.

Why Choose AltiPro Adventures for Cho-Oyu 2027?

Autumn 2027 — The Definitive Cho-Oyu Season

The best season for the Northwest Ridge route is autumn. The weather is more consistent after the end of the monsoon season on the Tibetan Plateau. Our schedule has been designed to take advantage of the good weather and the fresh snow. AltiPro’s early arriving Sherpa team will take care of all the challenging sections, including the serac wall, before your first rotation begins. This way, you can reach the top safely and efficiently.

Sharper Weather Planning

Climbers receive accurate weather forecasts for the summit, updated every six hours by our weather team. No more relying on luck! A confirmed 48-hour window of good weather is required before beginning the push from Camp III. This detailed planning allows climbers to be on the summit plateau when the weather is at its best.

Advanced Oxygen Support

Each climber is provided with five 4-liter oxygen cylinders, a personally fitted summit mask, and a regulator. The usage of oxygen will commence at Camp III (7,550m or 24,770 ft) and continue through the descent process in accordance with the rules and regulations of the region. Each Climbing Sherpa will also be provided with two cylinders of oxygen.

Smaller, More Focused Climbing Teams

In order to provide the highest safety and a personal experience, AltiPro has decided to restrict the total number of Climbers for the Cho-Oyu expedition to a maximum of 12 Climbers only. Each Climber will have his or her own one-on-one Climbing Sherpa for the entire duration of the expedition. This will provide a small team experience, and with the close health checks and support, Climbers are more likely to attain success on the summit.

Safety-Forward Climbing Structure

For the entire season, an Expedition Doctor will be stationed at Advanced Base Camp (ABC), where he will perform health checks on Climbers daily and keep a close eye on the amount of oxygen available. These safety arrangements will be in place even before the first rotation of Climbers, and thus, it is safer for Climbers to take up the challenge of climbing the 8,000er – Cho-Oyu.

Northwest Ridge Route — Cho Oyu via the Tibetan Plateau

The Northwest Ridge route, which began in 1954, is the main route for commercial expeditions on Cho Oyu. The route starts at Chinese Base Camp (4,900m or 16,076 ft) and goes through three high camps to reach the summit at 8,188m (26,864 ft). The route is accessed via Tibet, and it is a favorite route because it is easily accessible. The route consists of 30-40° snow slopes. It is a top-level goal for climbers because it has a large summit platform and is considered the best first 8,000ers for climbers.

Northwest Ridge Navigation - From ABC to Camp I (5,650m or 18,536 ft - 6,400m or 20,997 ft)

The expedition starts by trekking from Chinese Base Camp to Advanced Base Camp (ABC) at 5,650m (18,536 ft), which is the main center for the expedition. From ABC, the route follows the lower Northwest Ridge over glacier travel and steady snow slopes. This part is quite easy because a fixed rope has been set up by the AltiPro Sherpa team on this route. The climb from ABC to Camp I takes about five or six hours and is considered the main goal for this rotation. Camp I is at 6,400m (20,997 ft) on a safe ridge.

Acclimatization Rotations

1st Rotation: ABC (5,650m or 18,536 ft) – Camp I (6,400m or 20,997 ft) overnight – Return to ABC. First ascent of the Northwest Ridge. Initial high-altitude exposure above 6,000m (19,650 ft).

2nd Rotation: Camp I – Serac Barrier – Camp II (7,200m or 23,622 ft) overnight – Return to ABC. First crossing of the technical serac zone and overnight above 7,000m (22,965 ft). Full medical clearance assessment begins.

3rd Rotation (Optional): Camp II – Camp III (7,550m or 24,770 ft) overnight – Return to ABC. Recommended for first-time 8,000m (26,246 ft) climbers. Provides crucial exposure to supplemental oxygen and upper-mountain logistics.

Camp Breakdown

Camp I — Northwest Ridge (6,400m or 20,997 ft): This is the lower Northwest Ridge camp. It is a resting spot and a caching point before the difficult serac barrier.

Camp II — Above the Serac Barrier (7,200m or 23,622 ft):This is the main camp for the summit ascent. It is above the serac barrier and has excellent views of the Everest area.

Camp III — Upper Northwest Ridge (7,550m or 24,770 ft): This is the last camp before the summit ascent. Oxygen is required from here according to local regulations. This is the start point.

Final Summit Attempt (8,188m or 26,863 ft): Leave before midnight. The route is up a short rock step and then across the flat summit plateau. However, to reach the true summit, a difficult 1 km traverse is required at 8,100m(26,574 ft)or above. The lakes will be visible below at Gokyo. It takes 12–16 hours to complete the round trip.
