A beautiful little park about 15 minutes outside of Charleston. Not particularly well advertised or famous (likely the reason it remains pristine), it has a good reputation with local botanists and mountain bikers as well as those who just want to walk and enjoy the woods.
A note for the unwary: You will have NO PHONE SERVICE here. It doesn't matter what your carrier is. Take a map to get you out of the area and be prepared for a few hours without phone calls, texts, or internet service.
