The highest mountain in the world is Mount Everest, which is located in the Himalayas on the border between Nepal and the Tibet Autonomous Region of China. Standing at approximately 8,848.86 meters (29,031.7 feet) above sea level, Everest has long been the ultimate challenge for mountaineers. It was first successfully summited on May 29, 1953, by Sir Edmund Hillary and Tenzing Norgay. The mountain draws adventurers from around the globe, but climbing it poses significant risks due to extreme weather conditions, altitude sickness, and technical climbing challenges.
