About North Georgia. Leaf change brings thousands of people into the north Georgia mountains every year. In response to a number of inquiries, we have come up with our tips on observing the beauty of this yearly show of color and our favorite places to witness this splendid time of the year.

Though I got married in Hawaii (no leaf-changing color) and lived on the West Coast for many years, in the past 11 years in New England, I always expect peak color around my anniversary! My husband and I went up to the mountains 2 weeks ago (on the parkway) and the leaves were just starting to change. I have noticed that in the last week or so, the leaves are starting to change in Durham. If you are a picture person, wait for the sun to hit the tree colors just right for the ultimate picture.
