Well, obviously Rumple knows about all of the realms, as well as being able to travel at will in all of the magical ones. I mean, he goes to the LWC using his magic. His comment when he hired Robin would seem to indicate that he has the ability to go to Oz, and just knows that his presence would cause a few more problems than he has time for.

Regina was WELL aware of Wonderland. Even if she didn't know when she first shoved her mom through the looking glass, One of her first comments was about escaping the looking glass, to which Cora responded about Wonderland. And I feel confident that Rumple would have included some knowledge of other realms in his teaching, since his goal was to use the Dark Curse as a means of realm jumping on a massive scale.

Thing is, Regina is not powerful enough to jump realms by herself, or even spy on other realms. If you remember "The Jolly Roger" she had Emma open the mirror to find Ariel and Eric on Hangman's Island back in the EF.

Now, it may be possible for Emma, now that she is really gaining control of her magic, to open a portal back to the EF. And I kinda hope they do that at some point. Being able to adventure in the EF (or even other realms) in the current day opens some possibilities for stories that would simply not work in Storybrooke.
