Not going this year, instead trying Moose in BC. I have been 6 times and plan on going many more, but will never consider myself anything but a amateur. which part of BC? If coastal, it can be wet, foggy, snowing cold, windy and/or very hot and sunny. a couple things off the bat, flash light and small tarp, I would lose the spotting scope and tri-pod, outfitter likely has one and I have never had a use for. at altitude you want some sun screen. meat bags (keep stink and blood out of your pack), Get the best boots you can(and break them in), a water filter (steri-pen) just in case, expedition merino socks and some mole skin, Advil back and joint medicine. Take two knives (very rocky pelts)!I always take harness and half rope between me and buddy.
here is gear lists I have used in past:

I have learnt the hard way on many trips, what to take, how to prepare, etc. One big part of goat hunting everyone forgets or doesn't talk about is mental preparation and know how to push yourself but not to the point where your compromising safety (which is really important with goat hunting. I have learnt to push to get the best possible experience and trip but making sure I return to my family. I am not scared to say, I have cried, broke down, been awed, had the greatest experiences, all in several hours of a goat hunt.
Abs and legs are the most important, do squats, bells, running up very steep hills, balance exercises. "mental...mental....mental" empty your tank in several workouts (water, food-slow and fast sugars, etc.) and this will allow you to see your mental strength.
most important take lots of pictures until you think you have way to many and take a hundred more.
Please share what ever the outcome. good luck and savour the experience.
