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 Duke Creek Marina, as it is mapped here, you can explore part of the South-East side of the lake. With lots of private residences, it might be tough to find a shore location to rest.
