Dahlonega Square has been featured in many Hallmark Christmas movies. It'll be decorated for the holiday season in November. I HIGHLY suggest at least driving through if not walking around downtown Dahlonega while in town for our wedding.
My favorite wineries are Kaya, Wolf Mountain, and Cavendar Creek. There is a Wine Trail mapped out on the website. It's a great way to spend an afternoon.
Helen is a picturesque German town nestled in the North Georgia Mountains. Staying in a cabin is suggested for visiting Helen.
Dahlonega has incredible waterfalls. I suggest Amicalola Falls! Sawnee Mountain is a nice loop with a gorgeous view at the top of the mountain.
