Lake Anna is very large and has several marinas, to put in at. Because of its size, it is impossible to cover the whole area in one outing. You are welcome to explore the lake from different marinas, so you can see different parts of Lake Anna. From Rocky Branch Marina you can explore the midsection of the lake as it is mapped here. You may choose to make this a whole day trip or an overnight event. The Rocky Branch Marina is equipped with a campground.
