From Yuksam we engage either porters or yak herder's to carry our loads on the trail. This can take several hours so for the first day a packed lunch may be the order of the day. We follow a well marked forest trail that winds high above the Rathong river. The trail winds through forests of conifer and oaks, mosses and ferns and past frequent side streams that tumble down the hillside. On route there are plenty of opportunities for bathing although you must remember to pack you're insect repellent as midges are a problem on this section, particularly during the pre monsoon walk. After four to five hours the trail crosses a substantial bridge just upstream of the confluence of the Rathong River and the Prek River. From the bridge it is a further one hour ascent to the small settlement of Bakhim (2750m), where a single Lepcha family live. The Lepchas, the original inhabitants of Sikkim were forced to move to the remote regions when large numbers of Tibetans migrated to Sikkim in the 17th century. Although there is a Rest House in Bakhim, we normally camp in the forest immediately below the village.
