Parks and trails are a cornerstone of public health and quality of life. The Open Trail System Specification (OpenTrails) helps citizens get outdoors to enjoy them.

What is OpenTrails?

The Open Trail System Specification (OpenTrails) defines a simple, common format for public trails and associated geographic information. OpenTrails allows public land agencies to publish their trail data and developers to write applications that consume that data in an interoperable way.
