Kala Patthar, Nepal

Kala Patthar, meaning 'black rock' in Nepali and Hindi, is a notable landmark located on the south ridge of Pumori in the Nepalese Himalayas. Although not a proper mountain with a prominence of only (10 m or 33 ft), the ascent of Kala Patthar is very popular with trekkers in the region of Mount Everest, since it provides the most accessible point to view Mt. Everest from base camp to peak (due to the structure of Everest, the peak cannot be seen from the base camp). "The views of Everest, Nuptse Nup II and Changtse are spectacular from Kala Patthar and there are glimpses of the northern flank and summit of Lhotse. The world's highest webcam, Mount Everest webcam, is located here.

The ascent of Kala Patthar begins at Gorakshep (5,164 m or 16,942 ft), the original base camp for Mt. Everest. After a brief dip to an ancient lake bed (which now contains a small lake and a helipad), the ascent makes its way up a series of steep switchbacks before levelling off somewhat as it traverses to the eastern side of the mountain. The trail then becomes steep once again until it reaches the wind-swept summit ridge. From there, a five to ten minute scramble over boulders takes one to the top, which is marked with prayer flags. The full ascent usually takes between 1.5 and 2 hours. If the attempt is made starting from Lobuche, an additional two to three hours (one way) is required.
