Common Mistakes on Borasu Pass Expedition
Most injuries and failures on this trail can be avoided by making smarter decisions early on.
Assuming Har Ki Dun (11.6k) is the peak — it's just the start.
Bringing low-ankle shoes — lethal for a 17k ft pass.
Not checking the HP side snow-bridges — crevasse risk.
Lack of technical gear like gaiters and ropes.
