Actually, I'm not sure about the "Pocket dimension" aspect of the Infinite forest. I more imagined just a large forest with a magical boundry atht teleports from one side to the other, but with a few "holes" so that there is actually a way in and out besides magic.

I'd have to go back and rewatch, but wasn't David sent to the Infinite forest (in the S1 Finale) after being taken by Regina,  and Rumple enchanted the Ring to guide David to Snow (which would obviously include guiding him to one of the exit holes of the forest). If that is the case, it would also seem to imply that Maleficent's castle is hidden inside the forest, since David had to visit there before Rumple returned the enchanted ring.
