My neighbor said he hiked to Packwood lake Fri, I guess it is the same lake you are talking about. Is it like a 4.5 mile hike ? He hiked up at mid day, caught one 15" trout in a couple of hours. Just fished with small lures on a spinner. Said he had a great time. I've never been. He did say something about lure only, no bait ETC. I have not looked it up in the regs.
