As you enter this dungeon you’ll encounter numerous White Boes, simply do a Ground Pound to defeat them. Break the crystals in front of the stone, then push it forward.
In this next room you’ll find a White Wolfos, defeat it then head into the eastern room.
In the next room you’ll need to use the Goron Mask and jump a gap in the bridge. Start your roll as the first Freezard begins blowing and you’ll be fine.
From here, take off the Goron Mask and use the Hero’s Bow to shoot the bubble around Stray Fairy #1 to the right of the bridge. Stray Fairy #2 is in the middle pillar, both will need the Great Fairy’s Mask to lure them in.
The Dungeon Map
Jump the gap and go up the steps to reach a new room and find Stray Fairy #3 to your right. There is a Real Bombchu in this room, shoot it or walk into with your shield up to prevent damage. The large chest in the corner contains the Dungeon Map !
