The Lobuje Mountain consists of two different summits, viz. East and West with heights of 6,119 m and 6,145 m respectively. A continuous ridge connects them but there is still a sharp gap and a considerable distance between them. The East Peak is recognized as a trekking peak, whereas the West is known as an Expedition Peak.
Lobuje being an attractive mountain offers various existing routes and also a potential for new ones. The dark triangle of its rocky East face rises over the moraines of the Khumbu Glacier to a spectacular skyline, forming the south ridge.
The peak of Lobuje East is reached by descending a marked notch and climbing steep snowy slopes to the top. On most occasions, the mountain is climbed on the summit ridge only as far as a subsidiary snow summit, southeast of the true peak and before the notch. This peak is identified as the false peak. Laurence Nielson and Ang Gyalzen Sherpa made the first ascent to Lobuje East on 25 April 1984 although there are possibilities that others have reached the summit before. But no records are available.
