It is necessary to take professional mountain guides to complete a successful climb and this highest mountain in the world challenges many well-experienced climbers who are willing to climb it. Mt. Everest is accessible by two main climbing routes, the southeast ridge from Nepal and the northeast ridge from Tibet as well as many others less frequently climbed routes. The southeast ridge is technically easier and is the more frequently used route. The first ascent was made by Edmund Hilary and Tenzing Norgay in 1953.
