Drive to Yuksom through the tea plantations along narrow roads that drops  almost 1700m in 1& 1/2hrs. Crossing theRammam river on a suspension bridge , we enter Sikkim.  Another about 3 & 1/2 hrs drive  brings us to Yuksom, the old capital of Sikkim. Overnight stay in Lodge

After breakfast, set off on the first part of the trail from Yuksom (1,785 m). Trek through the village and its terraced before entering oak and pine forest high above the Rathong River. The trail is well defined, with substantial bridges over the side rivers. Just beyond the confluence of the Rathong and Prek rivers  the trail descends steeply to a substantial bridge. There follows a 600m ascent up the forest trail to the small settlement of Bakhim (2750m), offering fine  views down the Rathong Gorge to Yuksam. Overnight at Camp. Trek for 6/7 hrs.

The trail from Bakhim heads up through grazing meadows, and past the first rhododendron and magnolia trees, to the village of Tsoka (3000 M), from here you have fantastic views of the mountains. Tsoka is a comparatively new village, founded in the early 1960s when the Sikkim government granted this tract of land to Tibetan refugees who had fled over the border in 1959. The village consists of a dozen or so houses, a gompa (Tibetan Buddhist monastery), and rows of chortens (stone Buddhist monuments) lining the main trail..  From Tsoka, the path goes uphill at first, but once a reasonably high altitude has been attained, there are quite a few ups and downs. After about 4 hours of uphill walking we reach the clearing of Phedang ( 3650m)  where we spend a night  for acclimatisation before going up  above 4000m  at Dzongri. Overnight camp at Phedang.

A  short   uphill climb  from Phedang  brings us to the Deorali  view points  from where  we can have a good views of the snowy peaks. From Deorali we  go up and down on the ridge but they're all mild, and one invariably walks through gentle rhododendron covered slopes, with brilliant peaks and views on all sides. From Dzongri, the views of the mountains along the Singalila Ridge include Kokthang, Rathong and Kabru South, while Pandim and Jubonu (5936 M) are two of the highest peaks on the east ridge side of the Prek Valley. Overnight camp at Dzongri. Trek for 3/4 hrs.

Wake up early morning   and walk up to the Dzongri Top to see the sunrise over the mountains.  After breakfast side walk to Dzongri La , a pass  leading into the Bikbari valley and onwards to Nepal.  The walk to the pass takes and 1.30 hrs to 2 hrs one way.  Overnight camp at Dzongri.

After a breakfast, set off on the trail along the right bank of the river. After cresting the hill, the path drops into the valley and then crosses a bridge over the Prek Chu river. Thansing (3,800 m), an hour's climb due north from the bridge, is located below the slopes of Mt Pandim. Reach Thansing and camp near the Prek Chu river. Overnight tents. Trek for 4/5 hrs.

The trail from Thansing climbs gently north, up the valley, and follows a stream and alpine meadows. The trail along the valley has  a superb view of the south face of Kanchendzonga and the peaks of Pandim , Tingchinkhang and Juponu hover  above the valley. We camp a little below the Samiti Lake  at Lamune ( 4000m) as camping in the lake area is now not allowed due to enviromental reasons. After reaching camp, walk upto the Samiti Lake.  The trail then skirts a series of glacial moraines before crossing meadows again, and arrives at the emerald green lake at Samiti (4,150 m).  Overnight camp at Lamune

Thangshing. After an very early breakfast we head towards Goechala, crossing the Samii Lake The trail begins with a gentle upward gradient for about half an hour. The trail follows the glacial moraine north-east and then drops to a dry lake at Zemathang. A rough scramble over rocks and boulders with a rise of about 400 m will bring you to the top of the view point. The walk to the pass takes about half an hour more.  The climb from Samiti to Goecha La(5,002 m) would take between 4 and 5 hours. The Goecha La pass is formed by a depression between Pandim and the Kabru spurs. It overlooks the Talung Valley and commands a very impressive view of the south face of Kangchendzonga. Walk down back  to Thansing . This is a long day  of about 10hrs walk in total. Overnight in Tents
