The Nangpa La is the key to an historic trading route still used illicitly today to bring wood from the Khumbu forests of Nepal to build houses on the barren plains of Tibet. Mountaineers driving south from Tingri toward this pass en route Cho-Oyu or in more recent years the Rongshar Chu and the challenge of menlungtse (7181m), will be taken by the scale of this deep divide in the Himalayan. Tingri (4350m) where we spend further two nights acclimatizing. Then we drive tingri to base camp 5000m along rough way with jerking and bouncing through grassy plain leading up to Chinese base camp. We set up our camp at Tibet side base camp and stay two nights or more, depending on how everyone feels. We also make schedules of the yaks by that time. Base camp is temporary but comfortable affair with Nepali cook and dining tent. Above the base camp is in the heart of the Himalayan at 5700m surrounded by celestial peaks. There is also the high pass called Nangpa La nearby which is an old but still used yak track trading route follows the big snow scoop on the right in the between Nepal and Tibet. Expedition begins when you arrive to Kathmandu where you meet the staff of Ramdung Expedition (P) Ltd. in the airport and transfer you to hotel. Next day, we have introduction section with other climbing members & Expedition crews. Since then we make your Tibet visa and other necessary document for Cho Oyu Expedition. After 3 day, we drive you towards Nepal-Tibet border up to the Friendship Bridge through Arniko Highway, where the Chinese liaison officer and Chinese transport meet us. The expedition gears go by truck while we travel by Land cruiser 4wd or with comfortable Minibus. We take time to acclimatize with one night at Zhangmu (2300m) and two nights at Nyalam (3750m), which also gives us the chance to trek up high hills for acclimatization.
