Langtang valley trek begins from the lower Langtang valley, through the forests and along with the Sherpa villages and farmlands of the people. Many villagers are originally from Tibet. Once this route was an important trading route with Tibet, therefore, most of the villagers and peoples here still are involved in trade.

On the way of trekking, you can have a trek through Langtang National Park. But, wildlife is not easy to spot in a forest setting, we also have chance to see some wild animals and birds. Among them are the monkeys, musk deer, Pika and the national bird of Nepal, the colorful danphe.

We continue our Trekking to Kyangjin Gompa (3,740 m), which is the site of the Yala Cheese Factory. There is a STOL airstrip at Chhaldang, a short distance east of Kyangjin. While our visit to the Yala Cheese Factory, we can have a view of small lakes beyond Yala, where we reach within half a day walkfrom Kyangjin Gompa.
