Mount Everest, known locally as Sagarmatha in Nepal and Qomolangma in Tibet, is the Earth's highest mountain above sea level. It is situated in the Mahalangur Himal sub-range of the Himalayas, its summit marking part of the China–Nepal border. Reaching a height of 8,848.86 meters (29,031 feet), Everest attracts experienced mountaineers and climbers willing to hire professional guides. The mountain is revered by local people and presents immense personal and physical challenges to those who attempt to climb it.
Everest has two main climbing routes: the standard route approaching from the southeast in Nepal, and another from the north in Tibet. The mountain's key features include the barren Southeast, Northeast, and West ridges that culminate in the Everest summit, with the South Summit a short distance away. The North Face rises above Tibet, while the Southwest Face rises above Nepal, presenting daunting challenges such as the Khumbu Icefall. Despite being the highest point above sea level, other mountains are sometimes claimed as "tallest on Earth" using different measurements.
