As is the case with Charleston [1], Savannah’s outlying areas still bear the indelible marks of the plantation era. The marsh still retains traces of the old rice paddies, and the economics of the area still retain a similar sense of class and racial stratification.
While history is no less prominent, it is more subtle in these largely semi-rural areas, and the tourist infrastructure is much less well-developed than Savannah [2] proper. This area contains some of the most impoverished communities in Georgia, so keep in mind that the locals may have more on their minds than keeping you entertained—though certainly at no point will their Southern manners fail them.
And also keep in mind that you are traveling in one of the most unique ecosystems in the country and natural beauty is never far away.
