We will meet in Dahlonega at 9am and end up at Toccoa Falls by about 3 and return to Dahlonega by 5:30 or so.
So the whole thing is over in a day - but if you'd like to come to it, you could turn it into a weekend trip as there are other "tours" you could go on, Sunday. I might think about leading a smaller group on Sunday to other attractions/roads in the area. There are good hotels in Cumming, where I live, less than 45 minutes from Dahlonega.
