Langtang Lirung is a bulky mountain with a 10 km long west to east running ridge that culminates at its eastern end in the actual summit. From there the south face drops steeply for 2200 meters to the floor of a giant cirque from which the Lirung Glacier issues. Towards the western end of the long ridge is a significant notch beyond which rises the shapely peak of Chenge Lirung (6581m), also known as Langtang II, first- climbed in 1963 by the Canadian PeterTaylor.

This mountain is a serious challenge for any party, cause it is either technically very difficult (the west ridge), subject to a good deal of objective dangers (the east ridge), or both (the south face)However, for those who have just come to look, it is a beautiful peak in a very beautiful valley, the great cirque with the stunning south face being just an easy stroll from Kyanjing Gompa, the highest village in the Langtang Valley.

A very beautiful view of the southern and eastern aspects of the mountain might be obtained from the summit of Tsergo Ri (4984 meters), lying 10 kilometers southeast of Langtang Lirung, an easy daytrip from Kyanjing.The trip goes for 35 days.
