This is an introduction to Langtang trekking in Nepal among some of the most beautiful scenery in the whole country. Lying 30 km north of Kathmandu, Helambu is the most accessible trekking region in Nepal. The Langtang & Helumbu trek starts from Syabrubensi after driving 150 km from Kathmandu. The trail gradually ascends upstream along the Bhote Kosi river, passing through the forests of the Langtang valley to the alpine meadows and yak pastures around Kyangjin. After an ascent of Kyangjin Ri [4350m.], from where the 360 degree mountain views are truly spectacular, the trail retraces to Syabru. From here we trek further to the sacred Gosainkund lake situated at an elevation of 4336 meters and to Kathmandu via the lovely Helambu region.
