I've never been there, but ... out of principle for a mountainous region ... my suggestion would be this A) Really long primes. -- 300mm or 500mm B) Really short primes. -- Like a 17mm, 20mm, or 21mm C) zooms for the middle ranges. -- The 80-200/2.8 would be in the mid ranges. -- Just add a 35-70 & no more zooms. D) Extension tubes & 1.4x TC. Use the combination for your macro work. You won't need to add a macro lens to the kit by doing this.
May sometime I'll get a chance to go. Collin
