No amusement park, but if 0"0"0" interests you that can be found Only in Equador outside of Quito.
If you go there be careful there is the new place with a tall monument , and down the street to the right of that is a smallish museam which is where the GPS comes up as 0"0"0". Its not as fancy but a heck of alot more interesting, from being able to balance an egg on a nail head , to watching water go down the drain straight dwon, clock-wise alittle bit off 1way and counter clockwise when the sink is moved to the other side of the Real Equator. theres also a likeness of a native village and not filled like an Outlet Mall is and like the newer place is
