Reading a walk report at https://www.wildernessprime.com/expeditions/great-himalaya-trail/trail-notes/, the author says of the section from Khangpachen to Lhonak: "Trail was usually easy to follow with a few tricky areas. I made a mistake and ended up higher up the bank of the river traversing across a very dangerous landslide area. In the end I managed to descend safely to the river bed but then spent an hour scrambling over large boulders before I found the trail again."

It would be helpful to add difficulty tags here (e.g. sac_scale, trail_visibility). #surveyme
