If your doing a fully guided hunt, and everythings basically done for you besides your hunting gear. Then don't over stuff your pack. I did this, and found 70% what I had didn't even use. Be sure to carry alot of water or good sized hydration system. I kept 4 bottles water in my pack daily. The one thing I did use. Also for altitude adjustment expect headaches almost daily. If your from lower elevations you will most likely experience some sort of alititude sickness. Carry Alieve & rolaids. They helped alot, and what my outfitter recommended when I went.
