Kangchenjunga is the third highest mountain in the world. The huge massif of Kangchenjunga is buttressed by great ridges running roughly due east to west and north to south, forming a giant X. These ridges contain a host of spectacular 6-7,000 meter peaks, according to Summit Post. The climb is physically very demanding with long days and sections with a lot of exposure. The date rate is about 20 percent.
