Introduction to Camp No. 1: Camp No. 1 is also called Ski Hill Camp. It is 2,400 meters above sea level. Because it is close to the base camp, the noise from planes taking off and landing is loud every day. You need to wear earplugs when sleeping. This is a major risk. It’s dehydration, snow blindness, sunburn and heat stroke. From Camp 1 to Camp 2, the ascent is 580 meters, the distance is 4 kilometers, the journey time is about 6 hours, and the slope is moderate. Major risk: severe weather.
