Chinese base camp is located just below the Jabula glacier, also known as the Kyetrag or Gyabrag glacier (romanisations of Tibetan have not been finalized). You will rest for a day in Chinese base, to allow for packing and acclimatizing. Chinese basecamp is at around 5,000 meters/16,400 feet.
Advanced basecamp (ABC)-
ABC is located in a glacial moraine with views out to the Nangpa La glacier crossing between Tibet and Nepal. You then spend two days moving up to the "advanced basecamp" at 5,600 metres/18,500 feet, which is actually the true base camp for our climb. From here, you will complete your climb of Cho Oyu, not returning to Chinese base until your expedition is finished.
Camp 1 is located in a saddle at 6,400 meters/21,100 feet, at the base of the north-west ridge. The trail to Camp 1 crosses a flattish glacier, than a hill with loose scree and stone sometimes with snow. It is often referred to as the: "horrible hill" and is nearly always accomplished in sturdy trekking shoes, with good ankle support.
Camp 2 is placed just above a sloped section at 7,000 meters/23,100 feet.
Camp 3 is located on the northwest ridge-face at 7,450 meters/24,600 feet. You shall attempt the summit from Camp 3.
