American Discovery Trail Society

The American Discovery Trail (ADT) is a new breed of national trail – part city, part small town, part forest, part mountains, part desert – all in one trail. Its 6,800+ miles of continuous, multi-use trail stretches from Cape Henlopen State Park, Delaware, to Pt. Reyes National Seashore, California. It reaches across America, linking community to community in the first coast to coast, non-motorized trail. The ADT provides trail users the opportunity to journey into the heart of all that is uniquely American – its culture, heritage, landscape and spirit.
