Isle of Dubois is a very nice campground on the Lake. When you to Aubrey, there are 2 state park campgrounds, you definitely want the one called Isle of Dubois. You can reserve a site but not THE site. Basically a reservation guarantees you a spot but the spot won't be assigned until you arrive. They have a computer screen at the front desk that will show you the sites available or you can just drive around before you take a spot. We live nearby and like to go there for quick weekends.
