Faron Spring
From Zelda Wiki.org
Faron Spring is located just before the Faron Woods. This is where Link found one of the Light Spirits, Faron. He asked him to find the parasites that took his light. Once the Tears of Light, were retrieved, Link came out of his wolf form and received the Hero's Clothes.
In the Cave of Ordeals, upon reaching the 20th floor, the fairy will set free those little fairies into the spring.
