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. Opened in 2000, 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. (November 9, 2014)
The ADT is all about connections - people to people, community to community, urban areas to wilderness. It provides the opportunity for the most adventurous to travel from coast to coast, truly discovering the heart of America. More importantly, it provides millions access to a trail system that improves quality of life and protects our natural resources. The ADT connects five National Scenic, 12 National Historic, and 34 National Recreational Trails; passes through urban centers like Cincinnati and San Francisco; leads to 14 National Parks and 16 National Forests; and visits 10,000 sites of historic, cultural, and natural significance. It is truly the backbone of the National Trails System.
