Just across from Smithgall Woods State Park lies Allison Ridge Road. This short, well-groomed trail follows the base of Ash Mountain and briefly crosses the boundary into the state park and then into the Chattahoochee Wildlife Management Area. Popular with hunters, this trail had no obstacles or potholes, making it suitable for most passenger vehicles. The narrow trail and lush green canopy provide a feeling of seclusion before winter, and the lack of leaves opens views of the surrounding mountains through the trees.
This seasonal road is only open a few weeks per month, from September through December. The dates vary slightly each year. Check the dates before visiting via the Forest Service website.
