Lobuche east & Island peak (imja tse) expedition

Climbing two peaks is surely reason enough for excitement. Both over 6000m, Lobuche East and Island Peak are in east Nepal and the trek to these peaks leads through two high passes and Kala Patthar, the latter arguably the best viewpoint to see the mighty Everest range.

This expedition consists of not one but two climbs that present little technical difficulty and the crossing of two high passes. At first, we go up the Dudh Khosi, a river that has its source in the Gokyo lakes. The lakes are seen from the viewpoint of Gokyo Ri. After crossing the Cho La pass we head up towards Kala Patthar. We then embark on our first climb to the summit of Lobuche East (6,145 m) slightly more technical than Island Peak (a.k.a. Imja Tse at 6,189m) which we climb after crossing the second pass, Kongma La. We then descend from the valley of Imja Khola. On the way, we have a cultural moment as we visit the monasteries of Tengboche and Namche.

Besides the technical aspect of climbing that the guide will teach beginners, crossing passes above 5,500m can be stressful. Hence climbers are required to be in excellent physical condition.

- 2 ascents of trekking peaks over 6000 m can be undertaken even without mountaineering experience.
- 4 passes over 5000m to acclimatize to Gokyo Ri, Kala Patthar and the Cho and Kongma La passes.
- Excursions in the Khumbhu region, home to the highest peaks in the world including Everest, Lhotse, Cho Oyu and Makalu and many 7000m plus peaks like Ama Dablam and Pumori.
