The only attraction which I know is the Myrtle beach....becos its been for a long time I wanted to visit that . :cheers
The Riverbanks Zoo in Columbia is pretty nice and a great place to take kids, as is the EdVenture children's museum in downtown Columbia. and as the previous poster says, there's also Myrtle Beach. Not to mention beautiful and charming Charleston - which is great to visit anytime of the year, if you ask me. Plenty to see and do.
