From Samar, Gyan and I took a side route to visit the Rangbyung cave gompa, while the crew took the normal route via Bhena La (3830m) and Yamdo La (4010m). The trail was fairly dangerous to the top of a pass (about 4000m), steep, narrow and slanting with long drop-offs. If you visit Rangbyung, I would recommend going from Shyangmochen and then returning the same route, rather than this difficult and dangerous route. I had another excellent view of the Annapurna Massif and Nilgiri from the top of the pass (about 4000m) on the way to Rangbyung Cave in Upper Mustang. From left to right are Yakawa Kang (6482m), Thorung Peak (6144m), Annapurna (8091m), Tilicho Peak (7134m), and Nilgiri North (7061m).
