I live in Dundas, so the destinations I've been to are about the same driving distance. For me, Nakina is about my limit for an easy day's drive, being about 14hours....There's 2 very good outfitters there I've flown with in the past: Leuenberger's (leuenberger.ca/kag.htm), and Timberidge (timberidgefishing.com). With Leuenberger I can personally recommend Muskrat, Elbow, and Kapatawanga lakes. All fantastic fisheries, and great cabins. I'm fairly certain you'd have a good trip at any of their
