Langtang trekking 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, one 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 an airstrip at Chhaldang to Kathmandu, 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 walk from Kyangjin Gompa.
There is Kyangin Gompa located on the top of the valley, where we stop overnight and visit the local yak cheese factory and have a view of the glaciers, which is also a gateway to Tibet and we return back to Syabru village and make a trip to Sing Gompa, a place where the holy lake Gosainkund is situated and we cross the Llaurebena Pass (4610m), and continue south leaving the Langtang region and reach at Helambu valley and subsequently at Chisapani and return back to Kathmandu.
