Introduction,
On our trek we start in the lower Langtang Valley, trekking through its forests and among the villages and farmlands of its people, many of who are of Tibetan origin. Once an important trading route with Tibet, this influence is reflected in the character of the villages and peoples. During part of the trek you will be walking through National Park, and though wildlife is never easy to spot in a forest setting, there are chances of seeing some interesting animals and birds. Among those found in the park are monkeys, musk deer, pika and the national bird of Nepal, the colourful Danphe.

From Langtang village, the track continues to Kyangjin Gompa (3,740 m). This is the site of the Yala Cheese Factory. There is a STOL airstrip at Chhaldang, a short distance east of Kyangjin. Visiting to the Yala Cheese Factory (4.633 m) and the small lakes beyond Yala are worthwhile. Yala can be reached within half a day from Kyangjin Gompa.

From Kyangjin Gompa, a continuation to the pastures of Langsisa (4.084 m) provides the good views of numerous glaciers. There are some huts in Langsisa that can be reached within one day's walk from Kyangjin Gompa.
