High Altitude Sickness and Everest Base Camp. One of the major challenges facing trekkers heading to Everest Base Camp or any other high elevation trek in the Himalayas is dealing with the potential threat of High Altitude Sickness. The primary cause of High Altitude Sickness is a decrease in the amount of available oxygen with altitude.
Climbing Mount Everest is a four-day endeavor, not counting the seven day hike to Base Camp nor the two week layover where climbers allow their bodies to acclimate to the high altitude environment. Climbers begin their four-day Mount Everest climb at Base Camp located at the foot of the mountain. Climbers leave the 17,700 foot base camp, which borders Tibet and Nadas, and seek to reach Camp #1 located at 20,000 feet.
