The Legend of Zelda: Tears of the Kingdom Fire Temple Puzzle is what waits for you deep in the Chasm. A massive underground complex, it's where you'll conclude the main regional quest in Eldin/Goron City. Here's our guide to help you complete the Fire Temple Puzzle in Zelda: Tears of the Kingdom.

At the stopover point, there's a lower area with a breakable boulder. Use Yunobo's Rolling Fireball on it to reveal the first gong.

Continue along the tracks until you reach another stopover point. Turn around and have the arrow point to the right. This will let you ride the cart to the 2F junction.

Head to the left-hand side and switch the arrow. This will lower the rail, allowing the cart to cross the chasm. You'll then see a gong behind a barrier. You'll need to move the Zonai Hydrants so they make a continuous line of igneous rock platforms that you can cross.

While still at the 2F lock area, look behind you at the opposite chasm. Hit the same switch as before to raise the tracks. Ride the cart to the top now, which will take you to the 3F junction.
