Ganja La Pass
A remote 5,130 m glaciated pass linking the Langtang valley to Helambu, semi-technical and guided.
Ganja La is a 5,130-metre glaciated pass that links the Langtang valley with the Helambu region north of Kathmandu — and it is the most serious crossing among Nepal's great trekking passes. Unlike the well-trodden teahouse passes of Everest and Annapurna, Ganja La is a remote, semi-technical undertaking over steep snow, ice and scree, with no lodges on its high section and real exposure near the top.
Where it is
The pass crosses the high ridge south of the Langtang valley, connecting Kyanjin Gompa with the Helambu villages on the far side. It sits within Langtang National Park and is one of the seven great Himalayan passes of Nepal. It is the most committing route out of the Langtang region and a wild alternative to the gentler Helambu trek crossing.
Crossing the pass
The crossing is usually made south from Kyanjin Gompa, climbing past a high camp to the foot of the pass. The final ascent involves steep snow and ice to the prayer-flag saddle, after which a loose, exposed descent leads down toward the Helambu side. There are no teahouses on the high section, so trekkers camp and carry their own food, fuel and snow equipment. The full crossing typically takes several days of self-sufficient travel.
Difficulty and altitude
Ganja La is graded as semi-technical. Crampons, an ice axe and a rope are normally needed, and steep snow, hidden crevasses, loose scree and exposure all add risk. It demands an experienced guide and prior high-altitude experience; it is not a beginner's pass despite its modest height. As always, acclimatise carefully and watch for altitude sickness in Nepal on the high camps.
Best time and conditions
Aim for autumn (October to November) or late spring (late April to May) when snow conditions are most stable. Fresh snow, winter cold and monsoon rain all make the pass dangerous, and even in season a recent snowfall can render it impassable, so a flexible schedule and an honest assessment of conditions are essential.
Plan your crossing
Ganja La should only be attempted with an experienced guide, full camping and snow kit, and a conservative weather plan. Read the Nepal trekking guide for high-altitude preparation, and consider the easier Lauribina La pass above Gosaikunda if you want a Langtang-area crossing without the technical risk.

Frequently asked questions
How high is Ganja La pass?+
Ganja La sits at about 5,130 metres, crossing the ridge between the Langtang valley and the Helambu region north of Kathmandu. Though lower than the Everest and Annapurna passes, it is far more demanding because of its glaciated, semi-technical terrain.
Is Ganja La technical?+
Yes, by trekking standards. The pass involves steep snow and ice, a glacier, loose scree and exposed sections, so it is treated as a semi-technical crossing. Crampons, an ice axe, a rope and an experienced guide are normally required, unlike the easier teahouse passes.
Do you need a guide and gear for Ganja La?+
Yes. Ganja La is remote with no teahouses on the high section, so you must carry a tent, food and snow equipment, and trek with an experienced guide. It is not a route for unsupported or inexperienced trekkers and should only be attempted in stable conditions.
When is the best time to cross Ganja La?+
October to November and late April to May are the windows when snow conditions on the pass are most stable. In winter and after fresh snowfall the pass is dangerous or impassable, and the monsoon makes the steep terrain hazardous, so timing and a flexible schedule are critical.
