Of course you would do it the other way round (first the castle, then the ferry ride).

Also it is worth knowing that tickets are checked inside the ferry companies building before entering the gangway, but not on the boat or upon leaving. Furthermore you are not required to disembark from the ferry once you reached the other side of the Öresund. Reason is that there is a bar and a restaurant on the ferry so people often choose to stay and ride the ferry back and forth for a while on a single trip ticket which is kind of intended by the system. Then you should make up your mind on which side you want to leave and make sure to not leave accidentally on the wrong shore.

Third thing coming to my mind: There is the "Around the sound" 249 SEK round-trip ticket, which allows you to take the trains around the Öresund on both sides as much as you like as well as to cross the bridge once and to cross by ferry in the other direction. You can start wherever you like, you got two days for the travel and in my opinion this i a really nice offer. I did it last weekend with stops in Helsingborg, Helsingør, at the Louisiana museum and "København". You need a full day to do that though and you can easily fill two days if you prefer.
