California ParksMORE OUTSIDE. CLOSER TO HOME.

Good information.
A clearer picture.

Where our information comes from, when it was checked, and what we still need to verify.

How we build the directory

We checked all 283 entries in the official California State Parks directory and retained their evidence. One visitor page returned an error; its record remains an unpublished candidate. Protected parcels do not automatically qualify as public destinations. We retain unverified candidates outside the public directory.

The current directory has 279 public destinations and 21 candidates. The state directory is supplemented by selected federal and local destinations. Named OSM hiking routes and official state-park boundaries support trail and county associations. Wider federal, municipal, county, and nonprofit coverage remains incomplete.

Jurisdiction coverage

The statewide state-directory import is complete, including records withheld from publication where visitor access remains uncertain. County memberships use official park geometry where matched, or a documented visitor-map point. Local and federal inventories, practical details, and area-specific notices still have gaps.

Source checks

Notice and inventory checks have separate timestamps. Scheduled refresh is not yet enabled. A source failure leaves its prior notices in place. “Not yet checked” means that source has not been successfully ingested; it does not describe the conditions at a park.

Launch notice review

The October 20, 2026 review checked 487 visitor-page notice candidates: 108 were published, 360 rejected, and 19 deferred. Rejections include expired, duplicate, generic, and unsupported content. We also checked the agency’s significant-incidents dashboard for conflicts and gaps. Six source-backed guides explain recurring visitor issues. Supplemental notice checks appear with their own source dates.

Evidence and automated writing

Structured official notices are processed directly. AI-assisted interpretation and guides require recorded source evidence and an independent claim check. Ambiguous names, uncertain geographic impacts, or unsupported claims enter a review queue.

General seasonal guidance does not establish an infestation or closure at a specific park. Notices say whether their scope is a park, an area, or a region.

Maps and photographs

Park geometry is generalized for planning and is not a legal boundary or navigation product. Maps use OpenStreetMap tiles with attribution. Photograph credits and rights appear alongside the images. Destinations without reviewed photographs use compact text cards.
