Overnight camping; we walk gently uphill, following the Rathong River gorge, through dense mixed jungle with magnolia, rhododendron, ferns and several varieties of orchids, brightly colored birds, and the occasional monkey. After an hour or so we cross the Paha Khola Bridge, (1,733 mt). There is a swimming spot by the waterfall (for those who dare!) after two hours; we can stop for lunch by a bridge over stream. Passing by sweet smelling viburnum we cross the Prek Chu River and then ascend steeply for two or three hours to arrive at Bakhim. A little higher up is the picturesque Tibetan refugee settlement of Tshoka where we set up camp. This is a long trekking day and you should expect to be pretty tired by the time you arrive at the camp.

Overnight camping; a fairly steep climb above Tshoka takes you into beautiful rhododendron forests, and you continue along a well-defined uphill path to Phedang. Today we will cover a shorter distance in view of the climb to rarefied air.

Overnight camping; another short day's walking today, as we are now treading above the 4,000-meter mark. We will be setting up camp by lunchtime and suggest that you spend a relaxed afternoon acclimatizing. A brief climb beyond brings you to a meadow where we can pitch our tents in a campsite with views of Koktang, Rathong, Kabru, Kanchenjunga, Simvo and Pandim. As usual on trek the choice of campsite depends on many variables, one of the most important is the close supply of water.

Overnight camping; today we will explore the area, with the chance to climb the small peaks near to the campsite for tremendous views. This is particularly worthwhile in the early morning and the evening. While you can rest if you wish, there will be a short acclimatization walk around the local area to help prepare us for the next few days.

Overnight camping; today we ascend gradually over open hillside for a mile or so to a low ridge visible from the campsite (4,115 mt). From here, chortens and prayer flags overlooking fabulous views of Kanchenjunga and Pandim make ideal photo compositions. You then descend, at first traversing down towards Pandim on the far side of the valley, and then dropping steeply down on a good path through rhododendron forest to the Prek Chu River at 3,749 m for lunch (3 hrs). There is a new trekking lodge here that the crew may use for cooking. We cross the river and ascend gradually for one and-a-half-hour, through pinewoods to reach a grassy campsite, beneath the shapely unclimbed peak of Pandim. A new hut has been built here, which may be available for cooking and even sleeping.

Overnight camping; today's walk is fairly short to give you plenty of opportunity to rest before tomorrow's big day. You begin by continuing your walk parallel to the Prek Chu River. Sacred Samiti on the opposite side is a beautiful emerald green lake nestled in the midst of brightly colored wind-torn prayer flags.

Overnight camping; we have an early start today to beat the inclement weather condition that is common during the latter part of the day. Set off in the early morning climbing the hill behind the Lake before traversing the moraine and then descending to the sandy bed of an empty lake. The whole area above Samiti Lake is called the Zemathang Plateau. You cross this under the shadow of Pandim and then ascend moraine to a height of about 15,700 ft where you rest above a glaciated lake mottled with snow and icy pinnacles. The Goecha La Pass is another hour away. We traverse the lake and proceed across a slope, and then on a well-trodden path to our objective, which is festooned with brightly colored prayer flags. The views of the east flank of Kanchenjunga and the mountains and valleys in the distance are stunning. We then return to our campsite at Samiti Lake.

Overnight camping; it's worth getting up early to take a short hike to the ridge behind the camp. From here there are fantastic views of Kanchenjunga and one can look back up to the Goecha La. Leaving Thangsing, you take a different route, avoiding the long climb to the Dzongri Plateau. Descending to the Prek Chu, you contour around jungle to emerge at Phedang. Continue to Tshoka along another steep descent. This will save us a day on the return march, but does involve quite a long day.

Overnight in hotel; today you descend to the Prek Chu following the route you took up on the first day, and then contour gradually downwards to reach the village of Yuksum our starting point.
