We saw this alligator and a turtle from the boardwalk leading to the visitor's center. There is another boardwalk on the west side of the park on Highway 21. This looks similar to the ones we saw in the Everglades at the Anhinga Trail. It was still too cold when we were here to see much in the way of wildlife.
The war scenes for the movie Forrest Gump were shot near this marshwalk. (The park is near Parris Island Marine Corps Base.) During the summer months, a naturalist gives guided tours from this marshwalk and shares interesting facts about the marsh, vegetation, wildlife and it's importance to mankind.
I think the brick outline represents the place where the keeper's house was - it burned down. The other buildings are original to the lighthouse.
