Forest Temple

The Forest Temple is the name of a location that has made two appearances thus far in The Legend of Zelda series, the first one being in Ocarina of Time. The second, in Twilight Princess, and it has been confirmed to appear in Spirit Tracks.

Ocarina of Time
Deep within the Sacred Forest Meadow in the Lost Woods lies the Forest Temple, inhabited by many fierce foes. Since the stairway leading to the temple is now broken, the only way to gain access to the temple is by obtaining the Hookshot from the Kakariko Graveyard and grabbing onto a tree branch hanging off the top of the entrance platform.

The Forest Temple is an eerie, complex temple filled with strange puzzles and bewilderment, such as an array of switches which invert hallways. Most of its rooms and corridors are covered with moss and vines and hold enemies like the Skulltula and Deku Baba. The dungeon's interior design is reminiscent of a mansion or castle, with portraits hanging in certain rooms and quaint red carpets decorating the floor. The temple is home to the four Poe Sisters that lurk deep inside and guard the way to its master; Link must hunt down and destroy them to complete the temple. The first two sisters can be found in passageways with staircases (where the Fairy Bow can also be found), the third sister appears after Link solves a jigsaw puzzle and the final one returns to the dungeon's main chamber after the other three are defeated. The dungeon also features two wells that are connected to each other. It is also one of the few dungeons such as the Stone Tower Temple, in the Zelda series, whose structure can be altered—in this case, by twisting and untwisting hallways, revealing new paths.

The temple's music will also become a monster of its very own with its eerie but gorgeous tune and unnatural sounds. It's also the first temple where Link meets the dreaded Wallmaster in Ocarina of Time, and its boss is the fierce Phantom Ganon. Link journeys here to save his childhood Kokiri friend Saria only to awaken her as the Sage of Forest. Her power helps Link continue on his journey to free the other imprisoned sages.

Master Quest
Mostly, the locations of keys and locked doors have been changed. The two Wolfos are no more at the entrance of the Temple, but at the room where the first Stalfos was fought. It appears instead in a small connecting room. There are two extra blocks in the room with the block puzzle, but they serve no purpose other than causing confusion. The first twisted room is straight when it is first found, and is twisted by activating a switch, not with arrows. Several puzzles requiring Time Blocks are found, too. There are more Skulltulas and Skullwalltulas in the dungeon. In the room where the Floormaster was originally found (which is now found in another room) is a single ReDead. The well is now emptied by shooting an eye with the bow.

Trivia

 * The Forest Temple is known as the "topsy-turviest" level in Zelda history, followed by the Stone Tower in Majora's Mask. Nintendo Power also mentioned this once.
 * The dungeon's layout design shows that the temple exterior is shaped like a dome.
 * The Forest Temple was originally the Wind Temple but was changed later in development. This can also be noticed by the Forest Medallion which has an image somewhat similar to a tornado.
 * It is strongly believed by Team Beta Triforce  that the Forest Temple and Ganon's Castle were Hyrule Castle at a very early point in development, due to how the Forest Temple resembles a castle from A Link to the Past.

Twilight Princess
"Ever since the boss went funny in the head, there have been scary monsters everywhere..."

- Monkey from Twilight Princess

The Forest Temple is the first dungeon in Twilight Princess. It is housed within a massive tree in the Faron Woods that some theorize to be the dead remains of the Great Deku Tree from Ocarina of Time. It houses the Gale Boomerang which is used to defeat its boss, the Twilit Parasite Diababa. The temple is infested with Deku Babas, Baba Serpents, Skulltulas and Bokoblins.

The Gale Boomerang is used inside the temple to manipulate wind powered switches and bridges allowing Link to access rooms deeper within the dungeon. Monkeys have been imprisoned in various locations throughout the temple by their "chief", the mini-boss Ook. They must all be freed in order to gain access to the boss's lair, which, after being cleared, is considered by many to be one of the most beautiful places in the entire game.

This dungeon is different from the Forest Temple in Ocarina of Time in that it has only one level as opposed to multiple floors, and is far more organic in its design — though the first room of this temple is notably similar to its Ocarina of Time counterpart. Twilight Princess's Forest Temple is also similar to the Woodfall Temple in Majora's Mask in that a lot of the rooms seem to be very swamp-like.
