The day begins early from High Camp, usually before sunrise, due to the long and demanding crossing of Ganja La Pass. After breakfast, the trail immediately ascends steeply over rocky terrain and loose scree. As you climb higher, the landscape becomes increasingly alpine and rugged, often with patches of snow depending on the season.
The final push to Ganja La Pass (5,130 m) is steep and may require the use of crampons and ropes, especially in spring and early autumn. From the top of the pass, trekkers are rewarded with spectacular panoramic views of Langtang Lirung, Dorje Lakpa, Shishapangma (Tibet side), and Ganesh Himal. Prayer flags flutter at the pass, marking one of the most remote and adventurous crossings in the Langtang region.
After spending some time at the pass, the descent towards Keldang begins. The downhill section is long, steep, and technical, passing through snowfields, rocky slopes, and glacial moraine. Extra caution is required, particularly in icy conditions.
As the trail descends, the terrain gradually softens, leading to a wider alpine valley surrounded by dramatic mountain walls. By late afternoon, you reach Keldang (4,270 m), a beautiful and isolated pastureland used seasonally by yak herders. Camp is set here, offering a peaceful overnight stay beneath the towering Himalayan peaks.
This day is considered the most demanding and rewarding part of the Langtang Ganja La Pass Trek and is recommended only for experienced trekkers with good acclimatization.
