That’s a very beautiful area! Of course that’s true for pretty much the entire Lake District too. My wife and I did about a week of car camping and hiking along Lago Ranco and some of the streams that flowed into it, though we were not fishing at the time. I’d love to go back with fly rods, and I’ll bet you guys love it there. Do plan for rain! While mid summer is usually pretty idyllic weather, it can still rain anytime. I’m curious what month you are planning to go, for some reason I had though you were going this summer (ie more or less now). I’d think the time to go would be mid December through March, more or less?
