Mount Everest is the highest mountain of the world. It_fs height is 8,848 km. It_fs nick name are Qomolangma or Sagarmatha or Chomolungma. Mount Everest lies in the border of Nepal and China. Most of the part of the mount everest lies in the Nepal. So, it is said that mount everest lies in Nepal.

Trekking in EverestThe conditions on the mountain are so difficult that most of the dead body have been left where they fell. Some of them are easily visible in the climbing routes. Government of Nepal also requires a permit from all prospective climbers with a heavy fee. $25,000 (USD) fee is set for per person

There are mainly two route, southern and northeast climbing routes for climing Mt. Everest. Southeast is the frequently-used route to trek Mt. Everest because southeast routh is technically easier than northeast. Sir, Edmund Hillary and Tenzing Norgay had firstly climb in 1953.

The ascent via the southeast ridge begins with a trek to Base Camp at 5,380 m (17,600 ft) on the south side of Everest in Nepal.Expeditions usually fly into Lukla (2,860 m) from Kathmandu and pass through Namche Bazaar. Climbers then hike to Base Camp, which usually takes six to eight days, allowing for proper altitude acclimatization in order to prevent altitude sickness. Climbing equipment and supplies are carried by yaks, dzopkyos (yak hybrids) and human porters to Base Camp on the Khumbu Glacier. When Hillary and Tenzing climbed Everest in 1953, they started from Kathmandu Valley, as there were no roads further east at that time.

Base Camp Base Camp I In base _gCamp I_h climbers will spend couple of weeks, acclimatizing to the altitude. During that time, Sherpas and some expedition climbers (trekking guides) will set up ropes and ladders in the unfaithful Khumbu Icefall. Seracs, crevasses and shifting blocks of ice make the icefall one of the most dangerous sections of the route. Many climbers and Sherpas have been killed in this section. To reduce the risk, climbers will usually begin their ascent well before sunrise when the freezing temperatures glue ice blocks in place. Above the icefall is Camp I at 6,065 m (19,900 ft) Base Camp II _gBase Camp II_h, Advanced Base Camp (ABC) is established at 6,500 m (21,300 ft). The Western Cwm is a relatively flat, gently rising glacial valley, marked by huge lateral crevasses in the centre which prevent direct access to the upper reaches of the Cwm. Climbers are forced to cross on the far right near the base of Nuptse to a small passageway known as the "Nuptse corner". The Western Cwm as the topography of the area geneally cuts off wind from the climbing route. The high altitude and a clear, windless day can make the Western Cwm unbearably hot for climbers.

Base Camp III From ABC, climbers ascend the Lhotse face on set ropes up to Camp III, situated on a small ledge at 7,470 m (24,500 ft). From there, it is another 500 metres to Camp IV on the South Col at 7,920 m (26,000 ft). From Camp III to Camp IV, mountaineer are faced with two additional defy: The _gGeneva Spur_h and The _gYellow Band_h. The Geneva Spur is an anvil shaped rib of black rock named by a 1952 Swiss expedition. Fixed ropes help climbers in scrambling over this snow covered rock band. The Yellow Band is a section of sedimentary sandstone which also requires about 100 metres of rope for cross it.

On the South Col, climbers enter the death zone. Climbers typically only have a maximum of two or three days they can tolerate at this altitude for making peak bids. Clear weather and low winds are dangerous factors in coming to a decision whether to make a summit attempt. If weather does not cooperate within these short few days, climbers are forced to move down, many all the way back down to Base Camp.

Base Camp IV From Camp IV, mountainers will start their summit push around midnight with hopes of getting the summit (still another 1,000 metres above) within 10 to 12 hours. Climbers will first reach "The Balcony" at 8,400 m (27,700 ft), a small platform where they can rest and gaze at peaks to the south and east in the early dawn light. Continuing up the ridge, climbers are then faced with a series of impressive rock steps which usually forces them to the east into waist deep snow, a grave sudden large amount hazard. At 8,750 m (28,700 ft), a small table-sized arena of ice and snow marks the South Summit.

From the South Peak, mountaineer go after the knife-edge southeast ridge along which is known as the "Cornice traverse" where snow griping to irregular rock. This is the most bare part of the climb as a misstep to the left would send one 2,400 m (8,000 ft) down the southwest face while to the immediate right is the 3,050 m (10,000 ft) Kangshung face. At the end of this traverse is an imposing 12 m (40 ft) rock wall called the "Hillary Step" at 8,760 m (28,750 ft).

Tenzing and Hillary were the first mountaineers to rise this step and they did it with prehistoric ice climbing equipment and without fixed ropes. Now, climbers will ascend this step using fixed ropes previously set up by Sherpas. Once above the step, it is a comparatively easy climb to the top on fairly angled snow slopes - though the exposure on the ridge is extreme especially while traversing very large cornices of snow. After the Hillary Step, climbers also must traverse a very loose and rocky section that has a very large entanglement of fixed ropes that can be troublesome in bad weather. Climbers will typically spend less than a half-hour on "top of the world" as they realize the need to descend to Camp IV before darkness sets in, afternoon weather becomes a serious problem, or supplemental oxygen tanks run out.
