The Great Fairy Fountains' location is credited to
embjen@arn.net.
1) There is one at the Dead End near Hyrule Castle (When you're
a kid). Blow up the stone there and it should reveal a passage
to a Great Fairy's Fountain. The Great Fairy there gives you
Farore's Wind.
2) One is at the top of Death Mountain. Bomb the left passage
and it reveals a Great Fairy's Fountain. The one there gives you
Din's Fire.
3) There is one inside the Death Mountain Crater. Use the path
in Darunia's room and turn to the right and go across the bridge
(You need the Megaton Hammer to destroy the Red Stones there).
Once you destroy those stones, go inside. The Great Fairy there
will double your magic ability!
4) There is one in the Desert Colossus. Between the two palm
trees, there is a crack in the wall. Bomb it! It reveals a path
to yet another Great Fairy's Fountain. The one there gives you
the all-important Nayru's Love.
5) The last one is near Gannon’s Castle. Go down the path,
through the now destroyed gate, and there is a funny-looking
silver block at the Dead End (You must have the Golden Gauntlets
to lift it). Once removed, go inside the path to the Great
Fairy's Fountain. The Fairy in there gives you the most
important thing in the game---the ability to double your
defense!
6) At the east point of Zora's Fountain. (As a kid) Bomb the
stone that is connected to the east wall. Go inside to get the
magic ability.
