Water Temple

Water Temple (水の神殿, Mizu no Shinden) is the third major dungeon of the adult-Link portion of the game, and is where the Zoras pay homage to the water spirits. It is located beneath the waters of Lake Hylia at the base of the lake's largest island. The Water Temple is effectively a maze of chambers on four floors, some only accessible when the water of the temple is at a certain level. Part of the challenge of this temple is being able to raise and lower the water level effectively. The temple's main treasure is the Longshot. The Water Temple's Sage is Princess Ruto and its warp song the Serenade of Water. The Water Temple has been called the hardest temple in the game due to its water puzzles, although the difficulty has been greatly decreased in The Legend of Zelda: Ocarina of Time Master Quest.
