To mountain climbers, Kanchengjunga is more difficult and more dangerous to climb than Mt. Everest, the tallest mountain in the world. To climb Kanchengjunga, they need more mountain climbing skills and physical strength than climbing Mt. Everest. The slopes are steeper and there are more dangerous snowstorms and avalanches than in Mt. Everest. Besides, the paths up to the summit are less known to climbers than those of the Everest. One in every four climbers has died while climbing this 8586-meter high mountain. This makes it the most dangerous mountain to climb. The first attempt to climb the mountain was made by a Swiss expedition in 1905, but they were pushed back by an avalanche which killed one climber and three porters. After that first expedition, several other expedition teams risked their lives trying to reach the summit; many of them were killed in an avalanche or died after falling off a cliff. Some of them simply disappeared in snowstorms. For 50 years, climbers challenged its dangerous slopes and faced with dangerous snowstorms, strong winds, and avalanches. No one was successful in getting to the peak.
