Re: fishing near Ft. Collins, Co.--where to go?
Rocky Mountain National Park
Plenty of camping and fishing in the park. If you google it, you can find info on it with maps and campground info.
Great opportunity to chase some nice brookies, bows and brownies.
Felt soles are fine in CO.
If you want to stay closer to FTC, you could fish the Big Thompson and the Poudre. There's lots of "road side" campgrounds available.
