I do this in RMNP. Some of our hikes are 5 miles one way to fish. Therefore it's hiking boots and that's what I fish in. Just carry rod, reel, flies, nippers, tippet, spare leader, floatant, powder fly drier and that's it for fishing stuff. The rest is water, clothing layers/rain coat for weather and food. It all goes in a Camelbak backback. I don't wade and catch plenty of fish.
