1- MOUNT EVEREST

Mount Everest it the Earth's highest mountain, with a peak at 29,029 ft (8,848 meters) above sea level and the fifth tallest mountain measured from the centre of the Earth. Its location is in the Mahalangur section of the Himalayas.

Mount Everest attracts many highly experienced mountaineers as well as capable climbers willing to hire professional guides. There are two main climbing routes, one approaching the summit from the southeast in Nepal (known as the standard route) and the other from the north in Tibet. 

 While not posing substantial technical climbing challenges on the standard route, Everest presents dangers such as altitude sickness, weather, wind as well as significant objective hazards from avalanches and the Khumbu Icefall. While the overwhelming majority of climbers will use bottled oxygen in order to reach the top, some climbers have summitted Everest without supplemental oxygen.
