Everest Base Camp is either one of two base camps on opposite sides of Mount Everest. South Base Camp is in Nepal at an altitude of 5,364 metres, and North Base Camp is in Tibet at 5,150 metres (16,900 ft). These camps are rudimentary campsites on Mount Everest that are used by mountain climbers during their ascent and descent.
Supplies are shipped to the South Base Camp by sherpas or porters, and with the help of animals, usually yaks. The North Base Camp has vehicle access (at least in the summer months). Climbers typically rest at base camp for several days for acclimatization to reduce the risks and severity of altitude sickness.
The Everest Base Camp trek on the south side is one of the most popular trekking routes in the Himalayas and is visited by thousands of trekkers each year. Trekkers usually fly from Kathmandu to Lukla to save time and energy before beginning the trek to this base camp. However, trekking to Lukla is possible. There are no roads from Kathmandu to Lukla and as a result, the only method of transporting large and heavy goods is by plane.
In 2015, it was noted that about 40,000 people per year take the trek from the Lukla airport to the Nepal Everest Base Camp.
