Langtang Ganja la pass and helambu trekking starts from Sybru Bensi, ends at Melamchi Pul Bazar. From Sybru Bensi, you will follow the Langtang River to the east until you get to Kyanching Gompa (3,049.). In Kyanjing Gompa there is a small Buddhist monastery and a cheese factory started in 1955 by the Swiss Association for Technical Assistance. When you are crossing the pass there are spectacular views of Langtang Lirung and the Tibetan peaks beyond. Much of this route is spent above 3,000m.The highest point of this trek is Ganjala Pass (5,122m). On the very pass of Ganjala, the last few 100m trails are precarious so we use a rope there for safety, though the utmost care is enough. The descent from the pass is on a steep slope for over 1 km, which requires good care again. But the rest of the trail is easy and comfortable. As there are no lodges and no settlements for three days along the way, the group should be well equipped with enough food. Only organized camping treks are possible for this region. The use of firewood is also prohibited within the park, so all supplies should be taken with us.

After passing the Ganjala Pass, the trail takes you to Malemchi gaon and Tarke Ghyang. People here call themselves Sherpas but their relationship with the Sherpa of Solu Khumbu is distant. The dialects spoken are also different. People here follow the Buddhist religion so you will find many old Buddhist monasteries in the villages.
