The official Appalachian Trail Conservancy 12" x 12" wall calendar for 2025 features professional photography by users of the Trail. The captions include interpretive information about the Trail and points of natural and cultural history protected within its corridor by ATC and more than 6,000 volunteer maintainers in local clubs.
The dates grid is as large as possible at this size and appears atop a schematic locator map in the background for the image. The map pinpoints each location along the trail. Co-published by ATC and Rizzoli International/Universe Publishing since 2011.
