E2 - Islet of Steel
This is without a doubt the strangest island in the Great Sea. The building is made entirely out of steel, hollow, and has a grassy hill on top of it. The entrance to the steel structure is guarded by three Cannon Boats and some wall-mounted cannons. The only way to get up to the hill is to control a seagull with a Hyoi Pear.
POINTS OF INTEREST
SEA PLATFORM - To the south of the Islet of Steel is a single Sea Platform. It is guarded by several enemies - the most annoying being two Wizzrobe Acolytes. A chest will appear after defeating all of them.
SILVER RUPEE - from Treasure Chart 35
TRIFORCE CHART 1 - The Triforce Chart can be found inside the hollow stell structure. Destroy the Cannon Boat blocking the entrance {and the others, if you feel like it} and play the Wind's Requiem on the Wind Crest to get the Chart.

E3 - Stone Watcher Island
Stone Watcher Island is a simple circular island named for the big stone head dominating the center of the top area.
POINTS OF INTEREST
SEA PLATFORM - The Sea Platform southeast of the island is armed with 8 cannons. After defeating them {and wasting a whole lot of Bombs, probably}, a treasure chest containing a well-deserved reward appears.
TRIFORCE CHART 7 - Lift the stone head that gives the island its name to reveal the entrance to Stone Watcher Island's Secret Cave. Enter each of the four rooms and defeat the enemies inside to gain access to the final room. Defeat the two Darknuts to unlock the door with the treasure chest containing Triforce Chart 7.
TRIFORCE SHARD - from Triforce Chart 3

E4 - Southern Triangle Island
Here, as with all the triangle islands, is the statue where you place one of your three pearls. Other than that, it's a pretty boring place.
POINTS OF INTEREST
BEEDLE'S SHOP SHIP - can be found circling the island
TRIFORCE SHARD - from Triforce Chart 6

E5 - Private Oasis
This nice little island is home to the cabanna, owned by Mrs. Marie of Windfall Island. You can't get inside until you get the Cabanna Deed, so you won't be coming here for the first part of the game. Once you get the deed, however, the Oasis becomes yours and you can enter the cabanna.
POINTS OF INTEREST
BIG OCTO - The 8-eyed monster inhabits the waters around the Private Oasis. Look for the circling seagulls to pinpoint its location as always.
SILVER RUPEE - from Treasure Chart 1
SLIDING PUZZLE MINIGAME - After you have gained entrance to the cabanna, you will see a sliding puzzle game on one of the walls {the picture on the opposite wall shows you the finished puzzle}. The door-butler will instruct you on how to play the game, but it's like the real-life sliding puzzles. Winning the first 15 puzzles earns you 50 Rupees each; the 16th puzzle has a 200 Rupee prize.
TREASURE CHART 27 - After you have the Hookshot, use it to get up to the raised part of the island where the waterfall begins. Open the chest there to get Treasure Chart 27.
TRIFORCE CHART 2 - Take out your Hookshot inside the cabanna and use it to swing from the post on the ceiling. This opens a secret passage via the fireplace. Drop down below to get Triforce Chart 2.
WITHERED DEKU TREE - appears after beating the Forbidden Woods.

E6 - Bomb Island
As per many of the islands in the Great Sea, Bomb Island is named after its shape. Yes, you guessed it: a bomb. Funny how that works, isn't it?
POINTS OF INTEREST
GHOST SHIP - Under the left half moon, the Ghost Ship can be found off the coast of Bomb Island.
PIECE OF HEART #1 - from Treasure Chart 20
PIECE OF HEART #2 - As you may have guessed, there is indeed something to do on Bomb Island that's related to bombs. {go figure!} On the main part of the island is a big cracked boulder. Bomb it, and you'll uncover the entrance to a Secret Cave. The treasure hidden in this cave is another Piece of Heart.
SEA PLATFORM - The single Sea Platform can be found southwest of Bomb Island. Defeat the enemies to make the obligitory treasure chest appear.
SUBMARINE - Find Old Man Ho-Ho and follow his gaze to see a Submarine. Sail over there and enter. A few Bokoblins and some rats are all you have to worry about here. After defeating the Bokoblins, a treasure chest containing an Empty Bottle will appear.
WANDERING MERCHANT - One of the three Wandering Merchants can be found here on Bomb Island.

E7 - Bird's Peak Rock
Bird's Peak Rock consists of a small island and six spires rising from another bigger island. The area is populated heavily with Kargarocs and seagulls.
POINTS OF INTEREST
SILVER RUPEE - from Treasure Chart 36
TRIFORCE CHART 3 - To reach the Secret Cave hiding the third Triforce Chart, you will need to trigger the 6 switches atop of each spire. To make life easier, kill the four Kargarocs on the smaller spires. Use a Hyoi Pear to control a seagull and hit the 5 lower switches. Fly back towards you and climb to the same height as the highest rock. Dodge the Kargaroc and hit the sixth switch. Once you do this, the gate blocking the Secret Cave is opened, and you can claim Triforce Chart 3.

F1 - Diamond Steppe Island
Predictably, Diamond Steppe Island is in the shape of a diamond, and has several "steps" leading to the top of the island. You'll need the Hookshot before you can get anywhere here.
POINTS OF INTEREST
BIG OCTO - Look for the circling seagulls to locate the 8-eyed Big Octo. Once you defeat it, a ring of light hiding an Orange Rupee is left behind.
GHOST SHIP - Under a left gibbous moon, the Ghost Ship will appear off of Diamond Steppe Island.
GHOST SHIP CHART - Use your Hookshot to climb the island's "steps" by targeting each tree. Drop into the Secret Cave at the top of the island to recieve the Ghost Ship Chart. With this chart, you will be able to tell where the Ghost Ship will be under each phase of the moon, and you will finally be able to enter it.
PIECE OF HEART - from Treasure Chart 23

F2 - Five-Eye Reef
As with all the reefs, clear out the wall-mounted cannons for a prize. Strangely enough, there are no Cannon Boats to deal with this time.
POINTS OF INTEREST
SEA PLATFORM - The lone Sea Platform off of Five-Eye Reef has an interesting reward: a Golden Feather. If you've already given your 20 to Hoskit, you can sell it to Beedle.
SILVER RUPEE - from Treasure Chart 12
TREASURE CHART 41 - appears after you clear out the reef

F3 - Shark Island
Continuing the pattern, Shark Island looks exactly like a shark. There are actually several things to do here, so don't pass it by.
POINTS OF INTEREST
SILVER RUPEE #1 - from Treasure Chart 16
SILVER RUPEE #2 - The Secret Cave on Shark Island, which contains a Silver Rupee, is blocked by a ring of fire. To get past it, you'll have to hit all 4 switches scattered on the island. To start, I would recommend cutting down all the small trees. You'll have to hit the switches quickly, so you'll need room to run. Head to the "tail" of the island to hit the first switch by using your Iron Boots. Draw your sword as you run down the "tail" and hit the crystal switch there. Turn and run towards the "head" and step on the pressure switch. Get out your Skull Hammer and jump to the other "fin" and pound down the stake - which is the fourth switch. Drop down into the Secret Cave and prepare to fight! To get the Silver Rupee, you will face waves of Miniblin, Bokoblin, Moblins, Darknuts, and Wizzrobes. Once you defeat all of them, your well-deserved Silver Rupee will appear.
WITHERED DEKU TREE - appears after beating the Forbidden Woods

F4 - Southern Fairy Island
Just like all the other fairy islands, you can find the home of one of the Great Fairies here.
POINTS OF INTEREST
BOMB BAG UPGRADE - Use a Bomb to clear the entrance to the Fairy Fountain. The Great Fairy who lives there will grant you the ability to carry more bombs.
PIECE OF HEART - from Treasure Chart 4
SEA PLATFORM - The trio of Sea Platforms can be found to the southeast of Southern Fairy Island. Destroy cannons and enemies to earn your prizes.

F5 - Ice Ring Isle
This frozen island is the home of another one of the game's essential items. To even set foot on the island without being frozen solid, you will have to shoot a Fire Arrow at the icy air shooting from the center of the island.
POINTS OF INTEREST
IRON BOOTS - Sail to the northwest side of the island before thawing the island with a Fire Arrow. Be careful not to run too fast; the surface of the island is still very slippery. Navigate the island until you reach the floating icebergs and jump on for a ride. Once you reach the third iceberg, jump into the dragon's mouth and drop down into the Secret Cave. You'll need to slide down the narrow...slide...to reach a platform. Climb to the next slide and slide down again. Open the treasure chest to get the Iron Boots.
ORANGE RUPEE - After you get the Iron Boots, look for a ledge between the chest and the light beam. Put on the Iron Boots so you don't get blown away and walk toward the wind into the second Secret Cave. The enemies in this cave are frozen in blocks of ice; melt them one at a time with your Fire Arrows. After they are defeated, a chest containing an Orange Rupee will appear.
SILVER RUPEE - from Treasure Chart 17
TREASURE CHART 36 - Once you've gotten the Iron Boots and reemerged onto Ice Ring Isle, look around the perimeter for a chest frozen in a block of ice {there is a Yellow Rupee, too}. Thaw it with a Fire Arrow to open the chest containing Treasure Chart 36.

F6 - Forest Haven
This massive island is home to the Great Deku Tree and the Korok tribe. It is here that you will face your second dungeon: the Forbidden Woods. There are also many other things to do here, so you'll be coming back often.
POINTS OF INTEREST
BEEDLE'S SHOP SHIP - can be found circling the island
BOOMERANG - After defeating the miniboss of the Forbidden Woods your prize will appear: the Boomerang! This wonderful weapon can hit up to five targets at once and makes life so much easier. Treasure it dearly.
DEKU LEAF - After you get rid of the ChuChus infesting the Great Deku Tree, he gives you a special leaf to help you fly. The only problem is, it's located way up high in his branches. Use the Boko Buds surrounding him and your Grappling Hook to reach it. Remember to line yourself up carefully: it's a long fall!
FOREST FIREFLY - Once you have completed Lenzo's Pictograph Quest, he instructs you to bring him a Forest Firefly in order to convert your PictoBox into the Deluxe PictoBox. The Forest Fireflies are large lights that shine in rainbow colors: not the little green lights that are everywhere in the Forest Haven. You'll need to catch one in an Empty Bottle and bring it to Lenzo.
NINTENDO GALLERY - On the small island north of Forest Haven is the entrance to the Nintendo Gallery: the biggest sidequest in the game. To enter the Gallery, you need to get to its "island" off of Forest Haven. Use the Boko Buds and your Grappling Hook to reach the branch you first found the Deku Leaf on. Use the Deku Leaf to glide from here to another Boko Bud at about the same level. Glide from here to a large ledge and exit the Forest Haven. Once outside, a cutscene will show you the island with the entrance to the Nintendo Gallery. Set the wind to the north and glide over there. Once you're there, use a Hyoi Pear to gain control of a seagull. Fly back to the side of Forest Haven and look for an alcove with a crystal switch. Once you hit the switch, the Nintendo Gallery entrance opens and a ladder drops down from the island to make life easier for you. To become an official member of the Gallery, show the sculpter Carlov a color Pictograph of anything you feel like.
PIECE OF HEART - from Treasure Chart 31
TREASURE CHART 3 - To the south of Forest Haven is a tall island. Start your path inside Forest Haven, but when you reach the second grappling post, don't swing across, but climb to the top of the pole. Set the wind to the south and glide to the island. There you will find the chest containing Treasure Chart 3.
WITHERED DEKU TREE QUEST - In the cutscene after the Forest Haven annual ceremony, you will see 8 Koroks flying away to the Great Sea. Talk to the Great Deku Tree or visit any of the specified islands and you'll find out that the new trees aren't doing well. You will need to give each of them water from Forest Haven. Easy enough, right? Not really. After you get the Forest Water in an Empty Bottle, you have 20 minutes to water all 8 trees before it becomes regular water. You will obviously need the Ballad of Gales for this to work. If you use this route, you should be able to do it in time:

1. F7 - Cliff Plateau Isles
2. F3 - Shark Island
3. D2 - Greatfish Isle
4. E1 - Needle Rock Isle
5. E5 - Private Oasis
6. C5 - Eastern Fairy Island
7. B2 - Mother & Child Isles
8. A2 - Star Island

F7 - Cliff Plateau Isles
The Cliff Plateau Isles are basically a few small islands close together and a larger one apart from those. There really isn't too much to do here.
POINTS OF INTEREST
SEA PLATFORM - This platform to the southeast of Cliff Plateau Isles is guarded by several Wizzrobe Acolytes, but the treasure chest is there all along.
SECRET CAVE - Jump from the first few small isles and enter the Secret Cave on the third. The Cave itself doesn't have a prize; it's a way for you to reach the highest isle. To start, jump across the floating platforms to the grassy ledge. Defeat the Boko Babas and run {or walk, I suppose} the ramp. Go around the wall of thorny vines and kill the Boko Baba to turn it into a Baba Bud. Jump to the tree trunk from the Baba Bud and hit the boards across from you with a Fire Arrow to burn them away. Use the Deku Leaf to glide to the unblocked ledge and enter the light beam. You emerge on the highest isle where a treasure chest containing Treasure Chart 25 awaits you.
TRIFORCE SHARD - from Triforce Chart 5
WITHERED DEKU TREE - appears after beating the Forbidden Woods

G1 - Horseshoe Island
This island, named for its shape, is guarded by an army of Seahats and a Cannon Boat. Once you're on the island, you get to play a fun game golf.
POINTS OF INTEREST
SEA PLATFORM - Southeast of Horseshoe Island is a pair of Sea Platforms. Hitting the Pressure Switch on either platform makes a treasure chest appear on the other.
SILVER RUPEE - from Treasure Chart 9
TREASURE CHART 8 - To get this chart, you have to play 3-hole golf across the island. Pick up a Boko nut and throw it towards the flag in front of you. Don't go too close: vines will come up and block your way. If you miss, either blow the nut toward the hole with your Deku Leaf or try again. Once the nut gets in the hole, the vines dissappear and you can proceed. Use this same process for the second hole. On the third hole, you can only use your Deku Leaf. If you miss the hole, blow the Boko nut into the sea so another one grows into its place. After the third hole, enter the Secret Cave. After beating a Mothula and two Wingless Mothulas, the treasure chest containing Treasure Chart 8 appears.
TREAUSURE CHART 28 - When you win your game of golf, instead of dropping into the Secret Cave, set the wind to the east. Use your Deku Leaf to glide to the rock at the center of the island to claim Treasure Chart 28.

G2 - Outset Island
Outset Island is Link's home, and the place where the game will start. He lives here with his grandmother and his sister, Aryll. You'll be returning here often.
POINTS OF INTEREST
BEEDLE'S SHOP SHIP - can be found circling the island
ELIXER SOUP - When you return to Outset Island to visit Jabun, take a minute to visit your grandmother. You find her in her rocking chair, sick and delirious. Stand right next to her and release a fairy from one of your bottles. {With your newly aquired bombs, you can get one from the fairy fountain in the forest on Outset} The fairy will heal her, and she gives you the Elixer Soup. This soup restores your health and magic power, plus doubles your attack power until you first take damage. Plus, the bottle is so full that you get two servings! Unfortunately, you can only have one bottle of Soup at a time, but come back to Outset any time for unlimited free refills.
HERO'S SHIELD - After you rescue Tetra from the forest on top of Outset Island, you'll need to find something to defend yourself with before Tetra will let you come on her ship. Go back to your house and climb to the loft. Oh no - the shield is gone! Go back down to the main floor and talk to Grandma. She gives you the shield {after a short speech} to help you on your quest to save Aryll.
HERO'S SWORD - After you see Tetra being dropped into the forest, head over to Orca's house. He notices your "troubled" look and offers you a chance to practice with a sword. Complete his lesson and he presents you with the Hero's Sword.
HURRICANE SPIN - After you collect ten Knight's Crests, visit Orca and show them to him. In return, he teaches you the Hurricane Spin Attack. It consumes magic power, but turns Link into a...well...hurricane to take down anything around him.
ORANGE RUPEE - Look for the opening under the porch of your porch and crawl into it. Crawling around, you will see a small opening. Inside is a chest containing an Orange Rupee.
PIECE OF HEART - To get this Piece of Heart you'll need the Power Bracelets and a stash of All-Purpose Bait. Carry Abe's giant pig across the bridge over by Mesa's weed patch. Look for the dark soil in the corner by the ledge to the weed patch and the rock cliff. Throw the pig into that corner and spread some Bait onto the black soil. The pig should dig in the soil and unearth a Piece of Heart.
PIG COLLECTING - In the beginning of the game, if you want to be able to get the Piece of Heart mentioned above {and get some easy cash}, visit Rose, the woman standing in the pig pen outside of her house. She tells you that she's looking for a pet pig. There are a total of three on the island. The wild black pig is in the grass patch being watched by Abe, who gives you advice on catching pigs. The location of the pigs seem to be random, but there are only two others, not counting the black pig. After you get each pig, throw it in the pen and then talk to Rose. She will give you a Rupee for each one. When you come back after beating the Forsaken Fortress, you will find a GIANT black pig there, which Rose has kindly named after you.
WALLET UPGRADE - Once you have your Bombs, go to the forest {where you first found Tetra} and visit the local Fairy Fountain. Since the bridge is gone, you will need to stand on the very top of the [former] wooden end of the bridge and glide over using your Deku Leaf. Remember to set the wind to the west. In the beginning of the forest, you will see a giant cracked boulder. Blast it open to gain entrance to the Fairy Fountain. The Great Fairy there will grant you the ability to carry more Rupees.
SAVAGE LABYRINTH - Deep in the depths of Outset Island lies the Savage Labyrinth, a deep cavern of all the enemies you've ever fought! *cue the onimous music!* Anyways, you'll have to go here to get the necessary Triforce Chart, but you can continue even further to get an insane amount of Rupees and a Piece of Heart. It's also a nice place to go if you really just want to take on a bunch of enemies without going too far. The Labyrinth contains 51 floors, but you only have to make it through 31 if you're just here because it's necessary. It's good training, though. {Let it first be noted that I refer to the rooms with just pots and the light beam to the surface as "resting rooms"} Anyways, here's the breakdown of the Labyrinth, floor-by-floor:

1. Resting room
2. An insanely large number of Keese
3. 6 Miniblin

51. A Piece of Heart

G3 - Headstone Island
Headstone Island is rocky and barren; named, as you guessed, for the stone head in the center of the island. But it doesn't hide the entrance to a Secret Cave - it covers the entrance to the Earth Temple. Until you have the Power Bracelets there really isn't much reason to visit. The island is guarded by a single Cannon Boat.
POINTS OF INTEREST
EARTH GOD'S LYRIC - Once you get the Power Bracelts, come to the island and remove the stone head to reveal the entrance to the Earth Temple. Here you will find a large stone engraved with a new song - the Earth God's Lyric. When you get out your Wind Waker, the Zora sage named Laruto appears and gives you instructions.
MIRROR SHIELD - Your prize for defeating the Earth Temple's miniboss is the Mirror Shied - a shield that reflects light! It can be used against many enemies and will be essential within the dungeon and outside of it.
PIECE OF HEART - Take out a Hyoi Pear to control one of the nearby seagulls. Fly up to the very top of Headstone Island and fly into the Piece of Heart resting there. Once you've hit it, switch back to Link. When you do, Link gets the Piece of Heart.
SILVER RUPEE - from Treasure Chart 40
SUBMARINE - Do not attempt to enter the Submarine northwest of Headstone Island. Some glitch in the game makes Link fall right into the minefield when he enters the Submarine. There are Bomb Flowers everywhere, and Bombchus run here and there, throwing even more bombs at you. Keep moving and L-target them; then destroy them with your Boomerang. Your prize is Treasure Chart 14.

G4 - Two-Eye Reef
You should know the drill by now - clear out the reef for your prize. However, a trapped Great Fairy nearby will upgrade your Magic Meter if you free her.
POINTS OF INTEREST
MAGIC UPGRADE/BIG OCTO - Look for the circling seagulls and sail toward them. The 4-eyed Big Octo is different from the rest, though - when you kill it, a Great Fairy emerges! It turns out she had been trapped by the Big Octo for a while, as the Merman near this very reef hinted. As a reward, she doubles your Magic Meter.
SEA PLATFORM - The single Sea Platform southeast of Tow-Eye Reef is cannon-free, but it sure is crowded! After you beat all of the enemies you get a nice Purple Rupee for your efforts.
TREASURE CHART 13 - This Treasure Chart is your reward for clearing out the reef.
TRIFORCE SHARD - from Triforce Chart 8

G5 - Angular Isles
I'm not really sure if the Angular Isles should even count as islands - they're nothing more than two block structures covered with algae. Wait until you have your Mirror Shield to visit the Secret Cave here.
POINTS OF INTEREST
PIECE OF HEART #1 - This Piece of Heart is just waiting for you in a chest on top of the largest isle, but you'll have to work to get up there. Climb the block stairs on the eastern side and run around the lowest level. You should notice a very small indent on the ground - in front of that is a moveable block. {For future reference - the moveable blocks are the ones with the least algae on them} On the next level, look to your right for the next moveable block. Push that block off the ledge and along the wall. Climb up and you'll find yourself with two moveable blocks in front of you - stacked on top of each other. Pull out the bottom one halfway and climb them. From there, it's easy to get all the way to the top.
PIECE OF HEART #2 - from Treasure Chart 15
SILVER RUPEE - This Silver Rupee can be found in the Secret Cave under the smaller of the two islands. You can either use your Hookshot to reach the top of the island from your boat or glide there from the larger island using the Deku Leaf. Once you're inside, you'll see a pile of blocks the lead up to two intersecting light beams. Once you've solved the puzzle, reflect the light onto the transparent chest using your Mirror Shield. Reach it with the Hookshot or Deku Leaf to claim the Silver Rupee.

G6 - Boating Course
An island heavily guarded by Seahats, the Boating Course is a small little island where you can test your skills handling your boat {what else?}. The game is run by the sailor Loot.
POINTS OF INTEREST
BOATING COURSE MINIGAME - Talk to Loot to start this minigame. It's 30 Rupees to play, but it pays off. Basically, you have to sail around the roped-off area and get as many Rupees as you can and make it to the finish line before 4 minutes have passed. There are two kinds of barrels: ones floating horizontally, or ones floating vertically. Feel free to sail over the horizontal ones, but if you forget to jump the vertical ones you'll be thrown out of your boat. If you want to cheat a bit, go around the left side of the island instead of through the finish line. There are a total of 150 Rupees on the course. Each time you play, however, Loot lowers the time by 10 seconds.
SEA HEARTS CHART - from Treasure Chart 32
SUBMARINE CHART - Set the wind to the north and use your Deku Leaf to glide to the smaller part of the island. Among the grass you will see the entrance to a Secret Cave. To make the treasure chest appear, you have to trigger the three crystal switches. But to make life tough, a constant stream of Miniblin attack you relentlessly. As long as you don't get too frustrated by the Miniblin, this Secret Cave is actually pretty easy.

G7 - Five-Star Isles
Like the Seven-Star Isles and Star Belt Archipelago, Five-Star Isles is nothing more than five very tall spires guarded by Kargarocs. You won't be doing anything on the island; but near it there's some interesting things.
POINTS OF INTEREST
FULL MOON LIGHT RINGS - Under a full moon, 3 light rings appear near the isles, each hiding a Red Rupee.
GHOST SHIP - Under a right crescent moon, the Ghost Ship can be seen circling the isles.
PIECE OF HEART - from Treasure Chart 33
SEA PLATFORM - Destroying the cannons on the single Sea Platform southwest of Five-Star Isles makes a treasure chest appear on the platform itself. 2 Pirate Bokoblin guard it, as usual.
SUBMARINE - At the southeast corner of the Great Sea is yet another Submarine. Your only enemies here are a few Bokoblin and Keese. The reward is suprising, given the low level of difficulty.
