These line features depict official visitor\u2011use trails, including hiking paths, walking routes, nature trails, multi\u2011use 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\u2011sensitive, or non\u2011public 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.
