We stayed at Lake Hartwell State park in stie 98 which was a lovely lakeside site.  The sites on either side (96, 99) all shared a path to a small beach with lake access.  Most other sites in the Wiggins Loop did not seem to have lake access- exceptions being tent sites and the cabins.  There was some privacy and the sites were decently spread out, but since they were staggered a bit you could definitely see into other sites.

Nice camp store with helpful staff and firewood for sale.

Place was packed over the weekend but cleared out Sunday.
