We start our trekking in the lower Langtang Valley, trekking through its forests and among the Sherpa villages and farmlands of the people, many of them originally from Tibet.  Once this toute was an important trading route with Tibet, so that most of the villagers and peoples are involved in trade.
On the way of trekking, you trek through Langtang National Park. Although wildlife is never easy to spot in a forest setting, there we have chance to see some wild animals and birds. Among those can be senn in the park are monkeys, musk deer, Pika and the national bird of Nepal, the colorful danphe.
     At Langtang village, we continue 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.
As we visit to the Yala Cheese Factory, from there we view the small lakes beyond Yala, that can be reached within half a day from Kyangjin Gompa.
