Worth knowing

Some non-state beaches are unrestricted.

This is a plain-language starting point, not legal advice. The rules change and vary by county, city, park, and parcel, and federal land carries its own restrictions. Always confirm with the specific land manager or agency before you search, and record and report finds where the law requires it.
