In August they will be up high, as already mentioned...and there will be bugs. Don't know if you're going in/taking out on an alpine lake or sea level. Climbing on "the rock" can be pretty steep and interesting at times (especially salt to alpine)...dense alder thickets, thorned salmonberry vines, very slippery footing at times (especially when rain soaked), clouds that can move-in quickly and reduce visibility down to nothing up high...coastal mountain hunting in Alaska. That said, Kodiak is a very special place, and you are going to have an adventure for sure. I'll be back in November. Have a great trip sir!
