Drive west of Thunder Bay to Quetico Provincial Park (http://www.ontarioparks.c...) - some of the best canoeing in the world awaits!
You can also canoe on White Otter Lake, near Quetico and Atikokan. Visit White Otter Castle (http://www.atikokaninfo.c...), a 3-storey wooden cabin single-handedly built by Jimmy McQuat on the shores of the lake. Legend is that Jimmy built it for his sweetheart and then got jilted. There is a walking trail from the castle area that leads to an abandoned WWII POW camp, but this has not been restored for tourists. Be careful of rusted metal and sharp edges in the camp.
