Up to The bottom of the Well.

Zora's Domain:

Get two blue flames from the ice cavern, and melt
King Zora and the shopkeeper's red ice with it.
King Zora will talk to you and give you the
Zora's Tunic, a blue vest that will allow you to
stay underwater for an indefinate ammount of
time. Make sure to buy a bottled fairy from the
shopkeeper if you don't own one allready. You'll
definantely need it.

Water Temple:

The Water Temple is located under the island in
Lake Hylia that has a dead tree on it. Use your
Iron Boots to float down to the bottom of the
lake, and use the hookshot on the large gem above
the entrance. Hitting it with the hookshot will
allow access to the temple. The gem will float up
to the top of the water and will act like a
beacon to always tell you where the temple is

[Image]Some people say that its the hardest,
other say its easy, but all agree on one
thing: this level is HUGE! Find the large pool of
water and drop down (this room will be referred
to as the dungeon's "main" room) to the bottom by
wearing the Zora's Tunic and the Iron Boots. Find
the tunnel with two metal torches underwater and
enter it. You'll meet Ruto, the princess you
saved inside Jabu-Jabu's belly seven years ago.
She'll leave, and when she does, unequip your
Iron Boots. Float up to the top and you'll find a
triforce symbol etched into the wall. Play
Zelda's Lullabye to lower the water to the bottom
level. Go back down to the room where you met
Ruto and light the two torches by shooting an
arrow through the lit torch (huh?) or by using
Din's Fire. The metal bars will raise over the
doorway, and open the chest inside to get a
silver key.

Make your way back to the main room. Go to the
opposite side of the room, and push the moon
block into a hole at the tunnel's entrance. Enter
it and stop when you find a room with a crystal
switch. Hit the switch with any weapon and jump
on top of the water spout. This will serve as a
stepping stone for you to cross the chasm. The
next room contains a whirlpool. Trying to swim in
it will prove futile, so use your Iron Boots to
sink down to the bottom. Using the hookshot, hit
the crystal switch in the statue's mouth and
while the underwater gate is open, find the
hookshot target inside the passage to pull
yourself up to the passage. You'll find two
clam-like enemies. You can only use your hookshot
underwater to protect yourself, so avoiding them
will prove better off for yourself and your
hearts. Take off your Iron Boots at the dead end
and get the Silver Key at the top.

Go back into the dungeon's main room. Take a
right and look at the long pillar in the center.
Open the door, and go inside it. In order to gain
height in here, you must shoot the hookshot
targets with your hookshot. Find the Triforce
Symbol, and play Zelda's Lullabye near it. The
water will flood the dungeon half-way. Equip the
Iron Boots and sink down to the first floor part
of the pillar. Watching for spikes, find a hole
in the ground, and sink down to the Basement. Hit
the crystal switch in the room, and a few enemies
will drop down. Keep your distance and blast them
all with your hookshot. Float up where the grate
dissapeared (accessible after you defeat the
enemies) and get the silver key in the room.

Make your way into the pillar room. Float up to
the second floor and open the door. It will be
covered in Iron Bars after you exit. Go left and
swim to a door. Open it. Instead of hitting the
crystal switch immediately, go near the geyser
and wait for a Textike to drop down. Kill it, and
get on top of the water spout. Hit the crystal
switch to make the water rise. You'll go up to
the third floor. Exit the room and play
