Lobuche East is a “trekking peak” in the Kumbhu Region of Nepal. It is classed as Grade PD+ (Peu Difficile+) on the Alpine Grading system although it is rated as one of the more technical climbs within this group of peaks.
Certainly it is more technical than it’s more commonly climbed neighbours, Island Peak, Pokalde and Mera Peak. There are two summits to Lobuche East, a “true” and a “false” with an expedition peak Lobuche West adjoining.
There are a number of similar routes to the summit and this page describes the South East Ridge route. The first recorded ascent of this peak is surprisingly as late as 1984 by Laurence Neilson and Ang Gyalzen Sherpa. The main photo shows the general line of the south east ridge route as viewed from Pheriche.
