The Langtang Valley Trek commences from the lower Langtang Valley, weaving through the dense forests, picturesque villages, and farmlands inhabited by people with Tibetan roots. This region, once a vital trade route with Tibet, bears the influence of Tibetan culture in its villages and among its people. The trek offers a glimpse into the lives of the locals and their traditional practices.

As the trail progresses through the Langtang Valley forests, it takes trekkers into the Langtang National Park, known for its rich biodiversity. Though wildlife sightings can be challenging in a forested environment, there are opportunities to encounter intriguing animals and birds. Monkeys, musk deer, pika, and the vibrant Danphe (the national bird of Nepal) are among the fauna found in the park.

The trek leads to Langtang village and further to Kyangjin Gompa at an elevation of 3,740 meters. Kyangjin Gompa is notable for the Yala Cheese Factory, offering a unique experience for visitors. A short distance east of Kyangjin, there is a STOL airstrip at Chhaldang. Exploring the Yala Cheese Factory and the small lakes beyond Yala is recommended, providing additional highlights to the trek.

Continuing from Kyangjin Gompa to the pastures of Langsisa at 4,084 meters, trekkers are rewarded with stunning views of numerous glaciers. Langsisa, which hosts a few huts, can be reached within a day’s walk from Kyangjin Gompa. This section of the Langtang Valley Trek showcases the natural beauty, cultural richness, and diverse landscapes of the Langtang region.
