There are things to see in Hilton Head away from the beach. This pretty little park has hiking trails and is blessedly uncrowded -- there was only one other car in the parking lot when I arrived.
Despite the Audubon name, there weren't a lot of birds. I could hear them, but saw only a few flashes of bright feathers in the undergrowth. It was still lovely to walk on the trails with the trees towering overhead and sit on a bench by the pond and absorb the quiet.
