We've had good luck with Cygnet Lake up by Minaki.  You can bring your own boat or rent one of theirs and if you have ATV's you can bring those up and do day trips to other lakes or trails.  It's a smaller camp but the people are friendly.  It's owned by some people out of Wisconsin.  Fishing has always been very good for us.
