Lobuche East is the hardest of the trekking peaks that any mountaineers may try to attempt. There are two distinct summits to Lobuje Peak - Lobuje East (6,119m/20,070ft) and Lobuje West (6,145m/20,161ft). Although a continuous ridge connects them there is 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 is an attractive summit, offering a variety of existing routes and a 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 an icy skyline. This skyline forms the South Ridge, the junction of the East Face with the glaciated South-West Face and the line of the normal route of ascent. This in turn leads to the summit ridge running northwest from the top of East Face through several small summits to the East Peak.
