U.S Geological Survey National Digital Trails Network Project

The National Digital Trails Network project was developed in support of the Department of Interior’s vision to promote accessibility, connectivity, and the expansion of recreational opportunities on our Nation’s public lands. The overall objective of this project is to provide the data and the tools to enable land managers to visualize opportunities to increase connectivity within this network. The nationwide digital (GIS) trails database developed from this project has integrated Over 120,000 miles of trails (federal, state, local) since project launch, bringing the total of public domain trail miles to over 295,000 miles.
