The Ganja La pass situated at 5160m is one of the most challenging passes in Nepal. The Langtang trek takes you over this pass as you make your way south from Langtang village, which lies at 3500m & is the headquarter for Langtang National Park. The route from Gyang in Helambu, requires crossing the 5120 m Ganja La. The pass is often blocked by snow, so inquiries about local condition, good equipment & mountaineering experience are necessary for a safe crossing. The Helambu villages exude a Tibetan feel & you will see fields enclosed by stone walls as well as herds of yaks, the most important animal for the people here. From Tarke Gyang, we descend to Melamchi Khola before climbing to Patibhyanjyang, then trek down to Sundarijal, from where we drive back to Kathmandu.
