I think I'll have as many questions as I have answers. When you say camping,are you talking RV camping or tent camping? Do you want water and electricity or to really rough it.
You want to trout fish. Ok, fly or spin? Artificial or bait? Are you planning on bank fishing, wade, or boat? Solo or with a guide?
I'm partial to the White River and the Norfork River, but an hour further north puts you on North Fork of the White which is cool too. A little closer than the White is the Little Red which is a good place to fish, but I have zero experience there.
I'd be glad to help you fishing tips if you fish the White near Mountain Home.
