Cho Oyu is the sixth highest Himalayan peak out of 14th Highest peaks in the world and one of the most beautiful mountains of the world, it means "Turquoise Goddess" in Tibetan. It is one of the prominent Himalayan peaks for mountaineering expeditions. It has a great history of mountaineering right from the time when many mountaineers were trying their luck of Everest. The date was on 19th October 1954 Herbert Tichy, Sepp Jocher and Pasang Dawa Sherpa Lama (Austrian Expedition) had conquered to reach on top of Mt. Cho Oyu. There was an interesting fact about the expedition that bottled oxygen was not used. From that time onwards, more than 500 mountaineers have conquered successfully on top. Most of them have climbed from the Tibet side because the mountain is steep on the Nepal side but it looks fairly plain towards the Tibet side.
