How do you get to veil falls in the Minish Cap?

First you need to have visited King Gustaf at Royal Valley. He will give you a Golden Kinstone and tells you to place it at the source of the flow which is Veil Falls.

To get there you need to your ocarina to warp to Hyrule Town. When you get there head to Northeast hyrule field .Here are two boulders that can be blown up. Head right to enter Veil Falls. Right away you can jump into the water and you'll see a piece of heart on a piece of land so grab it.
