“If that’s the case, then the property owner is in the wrong, and thd beach is open to the public.”
That is not the issue. The issue is whether the public has a right to cross on his private land to get to the beach.
Didn’t know about that. If there’s no easement or right of way to that beach spelled out in the deed, then the county or state have a problem. Any such access would have been clearly shown in the legal description and land survey.
