Fire Temple keys, Goron cells and the Megaton Hammer

If you can see the boss door but lava cuts off the approach, remember that room. A pillar will drop into it later. For now, use the platforms on the left of Darunia’s room to free the first Goron and collect the chest key. Spend it across the entrance hall.

Rope bridge on 1F

Before crossing the long bridge, check both ends of the lava chamber. The northern platforms lead to a cell. At the southern wall, a bomb uncovers another. Take both chest keys, then cross east. When you reach the fire column, push the block onto it and ride the next eruption.

Boulders on 3F

On the maze floor, the northwest cell holds a key for the western exit. After the narrow walkways, follow the moving fire wall to the far steps. Push the block down to reach the upper ledges over the boulders. Bomb the cracked floor for one cell, then return upstairs. The southwest switch opens another cell across the ledges. Take both keys back toward the fire wall.

Invisible flames and the hammer chest

In the fire maze, check the north cell first. Work around the flame barriers to the inner southern door. Beyond it, carry a block onto the switch to keep the large barrier down. Defeat the Flare Dancer and ride the lift. At the timed chest upstairs, hit the small switch and run the inside edge of the slope. Open the chest for the Megaton Hammer.

Pillar down, boss door still locked

Hammer the large floor panels to descend. Near the Time Block, play the Song of Time and strike the switch to release the Goron. The round panel at the back of the cell drops the pillar. For the Boss Key, return to the entrance stairs on 1F, clear the east-side blocks with the hammer and follow that wing through a second Flare Dancer. The last cell holds the Boss Key. Return to Darunia’s room and cross the fallen pillar.
