We are starting to see some color in the lower elevations. If I had to guess a time for peak leaf viewing, I would guess the third week in October. I am not a professional peak leaf predictor, I am just going on my twelve years experience of watching the leaves change from the top of the mountain. Please don't hold me liable if it is earlier or later. When ever it falls, it is my favorite time in the Smokies. I love the cool, crisp, blue skies that October brings to the mountains.
