You can find this pier behind Nono's castle. Just follow the arrows and you should find it fairly soon.
You will recognize the entrance by the torch spam in the mountains.
There's a bunch of materials in the chests. Take some if you need it, just don't go overboard :p
If you climb the ladder to the left side, you will find a bridge that will lead you to my farms.
Here's a closer look at it. Feel free to use them, just replenish them later.
