This trek from Lachen to Green Lake at the base of Mt. Khangchendzonga in Zemu glacier in North Sikkim, is excellent for the close - up views of the Mt. Siniolchu, and Mt. Simvo. The views of the mountain peaks of the Northern ranges of Khangchendzonga from Green Lake are spectacular. It”s a high altitude expedition trek and one needs to be physically very fit to undertake the trek. The best time to trek is from April to November. In this trek the route to Green lake is the usual one followed by most trekkers, but on the way back we take a different route to end the trek at Chopta valley. Time permitting you will also go to the high altitude Gurudongmar lake.

The trail continues through forest on this day. After a short climb it crosses a bridge over Thombak Chu. There are several ascents and descends on the route, and is often wiped out of floods. Later we descend towards the bank of the Zemu Chu and follow the trail beside the river. After a tiring 8 kms day walk we reach the camping ground of Yabuk. Yabuk is a small but beautiful camping area very cold and windy near the glacier. Overnight in tents.

Day 7: Trek to Rest Camp (4500 M). (8 kms/ 3-4 hrs)
From Yabuk the trail enters the moraine field of the Zemu Glacier, crossing boulders and pebbles. It is a tiring route with increasing altitude and is like a walk in high altitude desert; though  later  one is rewarded with magnificent views of mountain peaks like Siniolchu and Simvo. At times one can also view Kangchenjunga rising in the distance. After a 6 kms walk we reach Rest camp at the mouth of Lhonak valley. Overnight stay in tents.
