The drive through the park is lovely, palm covered, "Don't feed the Alligators" sign on the bridge...There is a lighthouse, and gift shop, which I've never checked out. Try to plan your beach walk at low tide....there is not so much beach in places at high tide, due to erosion.
you will see the remains of trees bleached from being exposed to the elements on the beach for years. If you enjoy driftwood, there are very interesting formations on the beach...There is a Visitors Center where you can learn about the park, and plenty of facilities between the beach and parking, for restroom, shower and changing. Down the road past the entrance to the park there is a pier and Biology center with lovely views and wildlife is plentiful. Also there is a very long boardwalk which goes out over the marsh, which makes a nice sunset walk...just be sure to get back before dark! Hunting Island has a lot to offer...I didn't even mention the campground.
