Here is a great link for the Leaf Peepers! NHTourGuide.com offers details about the Fall Foliage season that includes a map of NH and the expected leaf color changes for the year. Check out the Fall Foliage Season Report & Details page of our site.
UPDATE: We had to remove the fall foliage report tool from our site. Best to read the posts, or ask a question in the fall foliage forum.
