Methodology & data sources

All listing data comes from the National Register database, the Recreation Information Database behind the National Park Service, via its full nightly database export. Data was last retrieved September 05, 2026; we refresh nightly and rebuild affected pages.

We normalize facility records, join campsite counts by type, roll campsite photos up to their listings, and link each reservable listing directly to its the National Park Service booking page. Where the export publishes no data for a field, we say so rather than guess.

Known limitations

• Reservability reflects the federal booking system; some first-come listings accept reservations through concessionaires we do not track.
• Site counts are as reported by managing agencies and can lag on-the-ground changes.
• Photos are the National Park Service media, credited as provided.
