Create a Hidden Page

I want to create a hidden page (not one that requires a password). I only want people to be able to access it if they have the link that I send them... but I don't want it visible on my site for all visitors. 

Create the page in the unliked section of your site, can't be seen on the nav bar or anywhere else without knowing the address of the page itself, which you can create in page settings in the slug field. So in effect it could be something like this "mydomain.com/hiddenpage" no password required.
