BETA - NPS Data Application Program Interface (API)

Welcome to the National Park Service (NPS) Data API. This API is designed to provide authoritative NPS data and content for internal and external developers creating apps, maps, and websites. You'll find photos and essential information about parks and their facilities, events, news, alerts, and more, as well as detailed articles about NPS natural and cultural features and important people and places.

The NPS Data API should be considered beta at this time. As the API expands over time, this documentation will evolve.
