WATCH: What Is It Like To Climb Everest?

Three people who have scaled Mount Everest explain what it is like to stand on top of the world. Bonita Norris is the youngest British woman to reach both the summit of Mount Everest and the North Pole. Ranulph Fiennes made it to the summit on his third attempt.

Kenton Cool is one of Europe’s best mountaineers and holds the highest success rate of any Everest guide. In May 2007 he summited the peak twice in one week.
