Overview
The National Park Service API provides data about US national parks, including park descriptions, alerts, visitor centers, campgrounds, and events. You need a free API key from the NPS developer site, which is quick to obtain. It is one of the most beginner-friendly government APIs with excellent documentation and consistent JSON responses.
Beginner Tip
Get your free API key instantly at www.nps.gov/subjects/developer/get-started.htm with just an email address. Use the parkCode parameter to filter results for a specific park, such as parkCode=yose for Yosemite or parkCode=grca for the Grand Canyon.
