The Special page you are looking for is Special:Categories.

You can get to that page via the Admin Dashboard, which is linked from the navigation bar on any wiki you are an admin on.

Or you can just go straight to Special:SpecialPages for a list of all of the pages you can access.

Hope that helps!
