The American Discovery Trail

The American Discovery Trail 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.


Help us get the National Discovery Trails Act (H.R.726) passed!

General Information

What is the American Discovery Trail?

The American Discovery Trail (ADT) is a cross country trail composed of many other existing trails and some unique connector routes between them. The trail is already contiguous across the continent, but the goal is to create a completely off road trail, that is still a work in progress. The ADT is different from trails like the Appalachian or Pacific Crest in that it is not a wilderness trail, it passes through cities, towns, farmland and wild areas.

Who operates the ADT?

The ADT is run by the American Discovery Trail Society (ADTS), a 501(c)3 non profit organization. The society is managed by a board of directors, all volunteers, and one paid part time employee – the administrator. Each state that the trail passes through has a state coordinator. There are of course many other helpful volunteers.
