Book early because Hunting Island is the most popular SP in SC. Also, early bookers get the sites close to the beach. We were interested to learn last winter while there for two nights that they have a discounted rate for longer term stays in that season.
Wonderful walk to the lighthouse. Close to Beaufort for day trips. Great shrimp off the boats nearby a la Forrest Gump.
We had a double rainbow over the beach as the day ended. I love the place, going back in 2014.
