For a $5 parking fee, you can explore this lovely island park. It's a peaceful retreat not too far from the faster pace of Savannah. There were bike rentals, but we decided to enjoy the park on foot. Since it was a warm, sunny day, we did not spend much time in the interpretive center. That will be a rainy day activity. We did not stay in the park campground, but it looked like a nice place to spend a few days or longer.
Georgia has a great Smartphone app that gives you lots of searching options. I like being able to find nearby parks with it.
