After reading [this question](https://anime.stackexchange.com/q/22379/6166), I
looked through some One Piece world maps as you can see below and they made me
wonder. Where would [All Blue](http://onepiece.wikia.com/wiki/All_Blue) even
be at? All Blue is supposedly the place where the four seas meet.

> The All Blue is a mystical sea of legend, rumoured to be the only place in
> the world where the North, South, East, and West seas meet.

Since the four seas are separated from each other by the Grand and Red line,
how and where would they be able to meet? Where would All Blue be at?

There is even [this interactive world map](http://khooz.com/) if you would be
interested.

Where is All Blue located?


Reverse Mountain. That's the only logical option right now - the currents are
formed from water of the four Blues so it connects on top of it. Maybe there
aren't fish from all Blues, but there is definitely water from all of them.

There is no canon or non-canon answer from the One Piece universe. Sanji
referred to a lake on Fishman island as his All Blue but that was not serious
(I think). Until Oda says, we don't know.

We could speculate it could be reverse mountain, or a bay at Raftel, or a
cavern deep underground, or Vegapunk's research aquarium on the moon, or an
alternative dimension (an island ate a devil fruit?), or ..... The point is
that Oda is very creative. It could be many things as a result.

Episode 530 around 22:41 Hody Jones says that "We will take the center of the
world, Fishman island". Fishman Island should be all blue, but then again
Fishman island is deep down...

The most predictable location would most likely be reverse mountain. After
all, that is the only viewable location in which all the Blues meet. It
instead could also be a deep lake that has underwater currents moving through
it from the Blues through caves.
