Fortnite Lighthouse Beam Rare Chest Quest (Chapter 7 Season 3)

One of the Week 4 weekly highlight quests in Fortnite Chapter 7 Season 3 asks you to use the lighthouse beam to reveal a hidden Rare Chest and search it. The trick is that the chest only exists for a few seconds while the rotating beam is pointed at it, so timing and positioning decide whether you finish in one match or keep running in circles.

Quick answer: Go to the lighthouse on the west side of Calamari Canyon, climb to the top, interact with the lamp to ignite it, then open one of the Rare Chests that appears on the rocks to the north-west when the beam sweeps over them. Opening a single chest completes the quest and awards 12,000 XP.

Lighthouse location in Calamari Canyon

The lighthouse sits inside the Calamari Canyon point of interest, near the coast on the western edge of the island. It is a tall red and white tower that stands out against the yellow desert terrain, so it is easy to spot once you are in the area.

The fastest approach is to drop straight from the Battle Bus and glide onto the top balcony. If you are already on the ground, head inside and take the stairs all the way up to the top floor.

Ignite the lamp and open a Rare Chest

Reach the very top floor of the lighthouse. The large lamp sits in the center of the room.

Walk up to the lamp and press the button that appears next to the word “Ignite” to turn it on. You will hear an audio chime, and the beam will begin to rotate.

Step out onto the balcony and watch the beam circle around. When it sweeps over the rocks on the north-west side, two Rare Chests appear, one next to a small boat and another on the furthest rock to the right. A bright purple beam in the sky marks where each chest is.

Use the Launch Pad on the lighthouse roof to glide straight toward a marked chest instead of climbing down and running. This gives you enough time to reach one before it disappears.

Interact with a Rare Chest while it is visible to search it. Opening any one of the chests revealed by the beam completes the quest.

How the beam and chests work

The chests are hidden until the beam illuminates them, then they vanish again once the light rotates away. They reappear every time the beam circles back, so missing one is not a problem. Wait for the light to point at a spawn point again, or move on to the other chest.

Confirming the quest is done and why it may not trigger

The moment you open a chest revealed by the beam, the quest objective pops and the 12,000 XP is banked toward your Chapter 7 Season 3 Battle Pass. If it does not register, the most common reasons are simple to fix.

You are at the wrong lighthouse. Only the one in Calamari Canyon works for this quest.
You opened a regular chest instead of one lit up by the beam. Only beam-marked Rare Chests count.
You were too far away and the chest despawned before you reached it. Use the roof Launch Pad and wait for the beam to point at a chest before launching.

Once you have searched a chest and seen the objective complete, you can head back out and pick up the rest of the Week 4 challenges. These quests stay available until the final day of the season, so there is no rush if the lighthouse is busy early in a match.
