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.
The ADT incorporates trails designed for hiking, bicycle and equestrian use. Because it connects five national scenic and 12 national historic trails, 34 national recreational trails, and many other local and regional trails — it is the backbone for the national trails system. It passes through metropolitan areas like San Francisco and Cincinnati, traces numerous pioneer trails, leads to 14 national parks and 16 national forests and visits more than 10,000 sites of historic, cultural and natural significance.
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 of people access to a trail system that improves quality of life and protects our natural resources.
Whether you set out for two hours, two days, two weeks, two months or more, your experience will be memorable. Nothing refreshes the human spirit more than being in touch with the natural environment. We're trying to ensure that this opportunity is preserved for you and future generations.
