Mount Everest
Base camps are at the bottom ("base") of the mountain. There are two base camps on opposite sides of the mountain: the South Base Camp in Nepal at  and the North Base Camp in Tibet, China at  high. The camps are simple places for people to rest, sleep, or eat when they go up and down the mountain. People often rest at the camps for about a week before they go up Mount Everest. Resting lets the body become comfortable with the thin air, so people do not become very ill with altitude sickness.
