According to TripSavvy.com, the best time to see Fall color in the upstates of GA and SC is from now through the middle of November.  If you need a destination, the reviews at Mountain House Restaurant in Cleveland, SC are mostly good.  This is very near Caesars Head State Park and is about an hour and a half from Fair Play, SC at I85.  Click here for a route with great views of Lake Keowee on the way by.  The Mountain House is open Tuesday through Saturday through mid-November for lunch, but you may want to give them a quick call to make sure.  And if you happen to miss meal-time, don't worry, they have fudge and ice cream, too.
