X: -532 / Y: 66 / Z: 384
This is one of the many places where you can see the island village from the main village. The coordinates also tell you roughly where the villages are. They're not that far, even though neither has a blacksmith, the two villages are quite useful!

This is where the island village is. The exact coordinates are on the boardwalk, but I'm sure you don't need to know that.
