Description: The National Park Service public Trails dataset provides geographic representations of publicly accessible trail routes across NPS units. These line features depict official visitor‑use trails, including hiking paths, walking routes, nature trails, multi‑use corridors, and other designated public routes commonly used for navigation, recreation planning, mapping, and interpretive information.This dataset is derived from the authoritative internal NPS Trails dataset maintained by park units and regional GIS programs. Only features appropriate for public distribution are included; restricted, administrative, resource‑sensitive, or non‑public trail segments have been removed. All spatial features are stored in NAD83 and undergo review prior to release.The dataset supports a wide range of public uses, including digital maps, trip planning applications, recreation tools, research, and cartographic products. It provides a consistent, nationwide representation of visitor‑oriented trail networks across the National Park Service.

Copyright Text: Trail data are contributed, reviewed, and maintained by individual park units and regional GIS programs across the National Park Service. The National Geospatial Program coordinates service‑wide data standards, quality assurance, and publication of this public dataset.
