Lobuche peak is an attractive summit, offering a variety of existing routes and wide scope for new lines. Seen from near Pheriche, the dark triangle of its rocky east face rises above the moraines of the Khumbu Glacier to and icy skyline. This skyline forms the south ridges, the junction of the east faces with the glaciated south west face and the line of the normal route of ascent. This in turn leads to the summit ridge running north west from the top of the east faces through several small summit to the east peak.
