I was sure my friend's party used a guide a couple of years back, this is from Google:

Hilton Head Inshore Guides

Hilton Head is loaded with smaller charters and guides that specialize in fishing the inshore waters around Hilton Head Island which includes the sounds and, creeks, and rivers. If fishing for redfish, trout, flounder, and those type of fish caught on light tackle is something you are interested in then you may want to look for a smaller charter boat in the 24' range and under, give or take a few feet of course.

Send us a report when you get back.
