This is nice little state park that preserves an overlooked later battle of the Revolution. There is a small museum that has information about the engagement (and the lighthouse on the property). The exhibits are fairly detailed but not overwhelming. There is a nice mix of information and artifacts, although an orientation film would have been helpful.
Outside the visitor center there is a walking trail that takes you to different points in the park. Trailside markers discuss the events at each location with good detail. Walking the grounds, it's easy to see why this was such an important strategic point and so difficult to assault. The pathway is a good climb at some points, but I think the worst was actually the hill they make you walk up from the parking lot to the visitor center.
