The snow range with Manaslu Peak (8,158 m) is aligned in north-south direction between the rivers Buri Gandaki (East) and Marsyangdi (West). The trek is a long course involving about three weeks but reveals many less frequented areas, particularly in upper Buri Gandaki Valley. The traditional approach route is from Trisuli Bazar that can be reached by bus from Kathmandu. From Trisuli to Arughat is about three days journey across inhabited hill country. Another shorter approach is to drive to Gorkha from Kathmandu and then a day's walk to Arughat. In any case, Arughat on the bank of Buri Gandaki river is the gateway to Manaslu area.
The first two days beyond Arughat is along low country with steep slopes. The next two days are across steep gorge which entails crossing the Buri Gandaki by suspension bridges at six places. It is a territory of dense forests and scattered Gurung villages. Beyond Jagat (1,350 m), Bhotia settlements become more numerous. Nyak village is at the confluence of Chhuling Khola (from west) and Shar Khola (from east). North of Deng, the valley opens out and there are impressive mountain views all around. These include Sringri (7,187 m) and Ganesh Himal (7,429 m) to the east, and Himalchuli (7,893 m), Peak 29 (7,835 m) and Manaslu (8,158 m) to the west. To the north appear innumerable small snow peaks that border on Tibet. From Prok village (2,000 m), it is another three days to Larke (4,450 m) camp site. In between are Bhotia villages of Namru, Lo, Sama and Samdu. Sama village (3,500 m) at the snout of Manaslu Glacier particularly provides close-up views of Manaslu.
Larke pass (5,213 m) marks the watershed between Buri Gandaki and Marsyangdi rivers. It is four hours climb from the Larke camp. Larke La opens vistas to the north-west of Himlung (7,126 m) and Annapurna II (7,937 m). The descent on the west side of the pass is much steeper until it levels at Bhimthang. It is two days descent to Dharapani on the Manang trail. Then begins the gorge section of the Marshyangdi until Bahundanda. This is again Gurung country. Dharapani to Bensishahar is an easy three days journey. During dry weather, vehicles are available at Bensishahar. During rainy weather, it is another two days walk to Dumre, on the Pokhara-Kathmandu highway.
