Cho Oyu Expedition

Cho Oyu Expedition

Mt. Cho Oyu is a technically easy and comparatively safe route which enables climbers with determination but not necessarily a high degree of technical expertise to reach an 8,201m summit. The safety precautions and logistical preparations are, of course, the same as for Everest and the standard of equipment is equally high. This is an ideal opportunity to experience the world of 8,000m and above with the least possible danger.

Mission Eco Trek has run expeditions to Cho Oyo since 2008, most of which have seen clients reach the summit. Cho Oyo is relatively easy to climb with minimal objective danger. It is a great opportunity to experience the surreal world of extreme altitude, to train for an Everest climb or to achieve a first 8,000m peak. Along with Everest, we specialize in this classic route and have a very high success rate. Although the challenge is perhaps less than that of the Everest climb, we ensure the same care and attention in the preparation of BC and ABC, the same detailed safety precautions on the mountain and, of course, the same degree of service from your guides and Sherpas.

Route Description

Above ABC (5,800m) we use three camps. Camp 1 (6,600m) is at the top of a long screen slope. From here the route is entirely on snow. We follow a gentle rounded ridge until we hit a short but steep ice cliff. We use a fixed rope to negotiate the cliff (normally about 20m) and then continue across a gentle glacier before we start another slightly steeper slope, again equipped with a fixed rope. Camp 2 (7,100m) is on an easy snow slope.

The day to reach Camp 3 (7,400m) is relatively short, about 3 - 4 hours, climbing more gentle snow slopes. From here we can reach the summit in 5 - 7 hours and return to Camp 2 for the evening. This final day consists of climbing intermediate snow slopes until we reach a series of rock bands, which we cross by way of their snow ledges. We come out onto a snow slope leading us to the summit ridge and then what is often mistaken as the summit. The real summit is still about 400m away on almost flat snow. The retreat is then fairly fast but with time to enjoy the spectacular surrounding scenery.

Mission Eco Trek is professionals at operating at high-altitude. Each trip we run has a realistic acclimatization programme. Our entire adventure trips are designed to allow gradual height gain, spread over a number of days. High altitude is not predictable sickness, so there is no way of predicting who will suffer from altitude but, for the vast majority of people, a slow ascent to height will produce minimal effects. We can provide 'Gamow Bag' as a precautionary measure as per your request on renting basis. Acclimatizing takes time and there are no safe shortcuts. All trips to altitudes in excess of 3,000 meters carry medicines essential to the treatment of altitude sickness, and our leaders, guides and staffs are well trained to administer them and to know the symptoms.
