"Hidden Page is only accessible in your control panel and not available from your site or search. Content can be viewed in preview mode or when editing the page. Its URL will not work." Hidden pages appear to be inaccessible after setting them to hidden. When setting a subpage to hidden it disappears from the subpage list of the parent page and can't be found again - you can find it if you go to 'your' pages, but if it is someone else's then you have no way of seeing it at all. Very annoying when you can't then delete said subpage to enable you to delete the parent page.
