As of May 2023, climbers from more than 60 different countries have successfully reached the summit of Mount Everest (8,848.86 m / 29,031.7 ft). Total successful summits approach 6,000, with hundreds of attempts each season. Nepal and China (Tibet) lead in total summits, reflecting their role as host nations and the large number of Sherpa and high-altitude workers from these countries who support expeditions. The first confirmed summit was by Edmund Hillary (New Zealand) and Tenzing Norgay (Nepal) in 1953.
