Nanga Parbat (Pakistan)
Nanga Parbat provides a lot of technical complexity that even the best climbers in the world are perplexed with its layout. In this aspect, it can rival K2 in terms of difficulty in ascending to the peak. The very first person to climb this mountain, Hermann Buhl, trekked through a slender rim around the mountain. The peak is known for its Rupal Face, a 15,000 foot high facade located on the southern portion.
