How to get into Wonderland?

So, I LOVE Alice & Peter Pan. -Fangirl Scream-
I just absolutely love it. But Wonderland seems so spunky. It seems so colorful, mysterious, and awesome. Talking flowers, hookah-smoking Caterpillars, disappearing cats? Oh lord! And a restless rabbit screaming, "Oh my, dear goodness, I'm late!"
And yes, I do believe in falling into a rabbit hole;P
I live in London, by the way. But also, anywhere else, is there a wonderland? SERIOUS ANSWERS, NO FOOLING.
