100's of them out there. Just cruise a favorite lake and find a place to pitch a tent on shore. It doesn't get any better than that! No firepit required in Ontario or outside provincial parks (when there are no fire bans on of course).
Most people won't advertise their favorite crowned land spots though since it lowers the odds of it being available the next time they want to go out and camp.
Rushing River has some nice looking lakefront sites though. So if you're talking places to pay to camp, that gets my vote for the best.
