Thanks for this great info, carolinadreamin! That is a great help for everyone looking for a short getaway nearby.
For any RVers, I highly recommend in addition to the State Parks that you check out
Palmetto Cove, which is located in an incredibly beautiful valley in northern Greenville County, between Table Rock, Caesar's Head, and Jones Gap State Parks. Be sure to print a copy of the brochure (High Res. (broken link)|Low Res. (broken link)) as well.
