Unconventional ways to get to different places
I was wanting to know more places that require some odd means or condition(s) in order to get there. Here's an example of the ones that I was able to think of: using a circle of mushrooms to enter Faeryland, or heading toward the second star on the right to reach Neverland. (I kind of thought that a rainbow was involved when it came to getting to Ponyland, but I can't seem to see any evidence of that, at least so far. The ponies just seem to fly up into the sky, and then down once at their destination.) I'm not sure if Oz counts, since I don't think the novels say anything beyond it being isolated by a (deadly) desert, and in the movie it seems to be a dream.
