The Green Flare Puzzle in Big Walk looks straightforward from a distance: fire a flare, follow it, grab a box. In practice, it is a two-player coordination test where the flare lands in a general area, but the actual prize — a hidden seaside box containing a red gourd — is tucked out of sight under rocks in a waterfront alcove. If your partner sprints toward the impact point and finds nothing, that is expected. This guide breaks down the full workflow, from communication setup to the exact location of the box, so you do not waste ten minutes circling the coastline.
What the Green Flare Puzzle Actually Does
The puzzle requires exactly two players. One fires the green flare from the designated launch spot; the other tracks its trajectory and follows the direction of travel. The flare points toward a box hidden along the coast, but not at the landing site. The box sits in a small alcove, concealed beneath rocks at the waterline. 
This is one of several green-themed puzzles in Big Walk, and if you are working through them systematically, you will also want to check out the Green Seat Speaker Headphones Sound Button Puzzle — a different challenge that uses the same color coding but a completely different interaction pattern.
Prerequisites: Two Players and a Communication Plan
There is no solo workaround here. You need a second player, and you need a way to coordinate the firing moment. Walkie-talkies are the cleanest solution — Player 1 calls out the exact second the flare leaves the launcher, and Player 2 locks onto the trajectory immediately.
If walkie-talkies are not available, the game gives you a built-in alternative: the flare reset timer. After firing, the green flare takes roughly one minute to reset. Player 1 fires once, waits for the reset, then fires a second time. Player 2 uses the second firing to confirm the direction and adjust their position. It is slower, but it works.
For broader map awareness while coordinating, knowing all communication points helps. The All 7 Radio Station Locations Guide covers every station on the map, which is useful if you are ranging far from the puzzle area.
Step-by-Step: Firing and Tracking the Flare
Here is the full sequence, assuming you have two players and either walkie-talkies or the patience for the double-fire method.
- Player 1 takes position at the flare launcher. Player 2 moves to an open area with a clear view of the sky and the coastline.
- Player 1 fires the green flare. It launches in the direction of the hidden box — not straight up, but at an angle toward the coast.
- Player 2 observes the direction immediately. The flare arcs and lands somewhere along the shoreline. Note the general trajectory, not the impact point.
- With walkie-talkies: Player 1 announces the firing moment. Player 2 starts moving toward the flare’s direction as soon as it launches.
- Without walkie-talkies: Player 1 holds the flare button, fires, and waits for the reset (~60 seconds). When the green flare is ready again, Player 1 fires a second time. Player 2 uses this second shot to confirm the bearing.
- Player 2 walks along the coastline, not inland. The box is at the waterfront, and following the shore is the easiest way to spot the alcove.
- Locate the alcove. The box is under rocks in a small recess at the waterline. It is not visible from the flare’s landing spot; you need to be close to the water to see it.
- Hold the box to open it. Interacting with it retrieves the red gourd.
Tip: If you are Player 2 and lose the flare’s direction mid-flight, do not chase the smoke trail. The flare lands, dissipates, and the box is never near the impact point anyway. Keep moving along the coast and look for the rock alcove.
Where the Box Is Hidden (and Why You Will Miss It)
The box is tucked under rocks in a small alcove at the waterfront. The flare may land within visual range of the alcove, but the box itself is concealed below the rock line — you cannot spot it from a distance. You need to be standing at the water’s edge, looking into the recess.

Walking the coastline is the recommended approach. Inland routes give you a worse angle, and the alcove is easy to miss if you are scanning from elevated ground. Stay at sea level and check every break in the rocks.
Warning: Do not assume the box is where the flare landed. The flare indicates direction, not destination. The box is always in the alcove, and the alcove is always at the waterfront.
