Cho Oyu Climb with International Mountain Guides

Thanks for your interest in our Cho Oyu Expedition climbs and treks. Cho Oyu is the 6th highest mountain in the world (8,201m) and is a classic Himalayan climb. IMG was one of the very first 8000m Himalayan operators to run Cho Oyu expeditions, and 2012 marks 18 consecutive years for us on the mountain and 23 years of running expeditions in Tibet. Since 1995 we have seen 193 climbers reach the summit of Cho Oyu with our IMG teams on the 22 expeditions we have conducted via the original 1954 route from Tibet. We're proud to have the best climbing record on the mountain. Our programs are recognized worldwide as well organized with first-rate logistics and experienced leaders, conducted under the direction of legendary climber and expedition leader Eric Simonson. We take great pride in running the best possible programs.

For climbers that want additional support we are also offering a Personal Sherpa Option. We will assign exclusively to you one of our very best Sherpas, who has summitted Cho Oyu and Everest many times, been through the Khumbu Sherpa climbing school, and who speaks English well. As a small, two-person team, you will be able to take advantage of the "best of both worlds" with all the "horsepower" of the main IMG team at your disposal in case of emergency, but also having the additional flexibility afforded by a climbing partner who is committed to climbing exclusively on your own schedule, when you want to. Your personal Sherpa will also be available to help carry your personal gear to the higher camps, and if desired, additional oxygen.

Note on Dates

Dates are listed starting with the arrival day to Kathmandu to the arrival day back to Kathmandu at the end of the trip. The ending date for the CHO OYU TREK is fixed. The ending date for the CHO OYU CLIMB is flexible, depending on weather and conditions. It would be normal to add at least 7 extra contingency days on the itinerary for the climb. If necessary, climbers will change their departure flights from Kathmandu when they know exactly when the expedition is going to end.

Spring vs. Autumn

IMG is no longer doing Spring expeditions to Tibet, due to the ongoing problems obtaining the Chinese/Tibet visas in the spring season. We have not have these problems with the visas in the autumn season.

But in general, Spring vs. Autumn... it's a crap shoot. Spring has less snow and avalanche danger, but has more ice and is more technical. The autumn can be good, but if you get a big snow dump (more likely in the autumn than spring,) you could be out of luck.

Spring starts out cold and windy, and gets better. Autumn starts out warm and wet, hopefully has a good stretch, then gets cold and windy later in the season. We try to climb in the spring during mid-May, when the weather starts to improve, and in the autumn during late September/early October before it gets too cold, and there are big snow storms.

Generally speaking, Everest is good in the Spring, less reliable in the Autumn. Cho Oyu is good both Spring and Autumn. There are probably more expeditions on Cho Oyu in the Autumn, since many companies are on Everest in the Spring.
