National Digital Trails


Connecting trails to expand recreational opportunities on the Nation’s public lands. 

The National Digital Trails Network project was developed in response to the Department of Interior’s (DOI’s) vision to expand recreational opportunities on the Nation’s public lands. 

Our Nation is home to a vast network of recreational trails traveled by millions of citizens. The trails are managed by numerous organizations and jurisdictions and do not form a coherent, connected network. The overall objectives of this project are to provide data and tools to enable land managers to visualize opportunities to increase the connectivity within this network.
