Cho Oyu is a beautiful mountain in its own right, and an excellent choice for those thinking of climbing Mt Everest in the future.

Trip Overview

North West ridge route

Standing 20 km to the west of Mt Everest on the Nepal-Tibet, China border, Cho Oyu is a true Himalayan giant. At 8,201 m it is the 6th highest peak in the world and an excellent objective, be it for your once-in- a-lifetime 8,000m peak, or as your final preparation before attempting Mt Everest.

Our attempt to summit this mountain will be via the (normal) NW ridge route, which is the original route used by the Austrian team who were the first to climb the mountain in 1952.

Subject to conditions prevailing at the time, we will fly to Lhasa to commence the expedition from there, or we will cross the border between Nepal and Tibet, China, by land – either way, the cost is covered in the quoted cost for this expedition.

After we drive to and arrive at Chinese Base Camp, we then have a two-day trek before we arrive at Advance Base Camp, from where we tackle the mountain via the placement of three high camps.

The climbing on the mountain is relatively straight-forward, with the two cruxes being a short but steep ice-cliff between Camps 1 and 2, and a prolonged, steep rock band directly above Camp 3.

Given the extreme altitude, the mountain is a very serious objective and neither the climb nor your preparation for the climb should be taken lightly. You’ll need to be as fit as you can possibly be, and when you’re climbing through the rock band above Camp 3 on your summit push, you’ll understand why! Once we reach the cusp of the summit plateau in the early hours of the morning, you’ll have to summon the energy to cross the wide plateau at over 8,100 m before finally standing on the main summit. Many choose not to go the extra distance to reach the main summit, as the height difference is minimal – but with Expedition Base, we like to complete the mission – therefore across the plateau we will go. If the weather is clear, once you are on the summit the spectacular panorama will make it all worth it. From the summit, you’ll be able to see Shishapangma, Gyachung Kang, Kanchenjunga, Lhotse, and of course, Mt Everest! This is an amazing climb in its own right, and in addition, it is a great preparation climb before you decide to tackle other higher or more technically challenging 8,000m peaks.

Why join with Expedition Base?

When it comes to mountaineering expeditions, for any peak, we are known for our sound strategy, strong leadership and well-resourced approach to our expeditions. The mountains are fun and full of wonderful experiences. But, we also recognise that they also carry with them risk. For that reason, we approach the mountains on the basis of ‘safety first’. With safety as our first focus, fun and amazing experiences will follow. Few companies offer logistics as good as ours for a reasonable price point. Our goal is to put our clients in the best position for success, whatever their personal goal in the mountains may be. Our guides are some of the best in the business, with experience on a wide range of peaks from small, right up to the 8,000m peaks, many with multiple summits on the 8,000m peaks. We see strong leadership as critical to success on the world’s highest peaks and we can offer that leadership here at Expedition Base – and not all companies can. We offer the level of services historically offered by leading western companies, but without costly western overheads. In the mountains, your safety is our prime importance. We know our clients value our commitment to them and with that flows a great experience.
