When I was younger my dad would take us up to Lac Des Mille Lacs. There are several camping/resorts up there now. And they actually tarred the road to get into it a few years ago. I don’t have much info on it myself anymore, but try this url:

(or just search on Yahoo for “Lac Des Mille Lacs, Canada”
That lake is great for Walleye and Northerns! Just make sure the anchor is tied on good. We lost a few in the rocky bottom.
