Everest base camps refers to two base camps on opposite sides of Mount Everest. South Base Camp is in Nepal at an altitude of 5,364 metres (17,598 ft.) while 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. South Base Camp is used when climbing via the South East Ridge while North Base Camp is used when climbing via the North East ridge. Every year thousands of individuals take up this challenge, many to fulfil a lifetime ambition often accompanied by a commitment to raise funds for a charity close to their hearts.
