Big Walk Coordinates & Secret Locations — Full Guide

How Big Walk's coordinate system works, every known coordinate location (4166 1899, Yellow Tower, tunnels), plus the game's best-kept secret locations.

Big Walk Coordinates & Secret Locations — Full Guide

Big Walk hides a full coordinate system under its chill exterior. Once you unlock the map room, the island becomes a navigable grid — and several puzzles and secrets only make sense once you can read it. This guide explains how coordinates work, lists every known coordinate we've confirmed, and rounds up the game's best secret locations.

Here's what you'll learn:

  • How to unlock and read the coordinate system (map room + GPS)
  • The famous 4166, 1899 puzzle, solved with coordinates
  • Every confirmed map coordinate (Yellow Tower, tunnels, control panels)
  • The secret shiny room and other hidden rewards

How Coordinates Work in Big Walk

Coordinates only matter once you've unlocked the tools to read them. Here's the chain:

  1. Complete the Red Tower — place five puzzle rewards in its console, shape the key, and open the room next to the session spawn point (some players call it "the gym")
  2. Inside, a massive 3D map on the floor shows the entire island — every puzzle location, every MacGuffin, every landmark (but no coordinates)
  3. A paper map on the table inside the same room does have coordinates — grab it
  4. Optionally, find the GPS device (a light-blue box showing your current latitude/longitude as two four-digit numbers) — it lives just southeast of the Green Tower near the ski lift station, and makes travel much easier

Coordinate format: two four-digit numbers — latitude (Y-axis) and longitude (X-axis). Big Walk's map uses four-digit grid coordinates like 4166, 1899; find the point on your paper map and walk there.

Unlock the map before any coordinate work

The 3D map, the paper map and the GPS are all gated behind the Red Tower. If you're staring at a number puzzle and haven't done the Red Tower yet, that's the missing piece — not the puzzle itself.

The 4166, 1899 Puzzle (Coordinates in Action)

The most famous coordinate puzzle in Big Walk: a gourd locked in a box under a sign reading 4166 and 1899. The numbers are map coordinates.

How to solve it:

  1. Complete the Red Tower and grab the map from the map room
  2. Plot the point (4166, 1899) on your paper map (X = longitude, Y = latitude)
  3. Walk to the rock at those coordinates
  4. Optional: carry the GPS box to verify your position on the way
  5. Press the button at the rock — the gourd box unlocks

Some sources list this under the Red Tower, others under the Green Tower — whichever you find it under, the solution is the same: 4166 1899 = coordinates, follow the map.

All Confirmed Map Coordinates

Confirmed coordinates from walkthrough sources (Screen Hype + Polygon + Destructoid):

Location Coordinates
4166, 1899 puzzle button (rock) 4166, 1899
Yellow Tunnel (southeast of Yellow Tower, across from a blue structure with a backpack) 3500, 1620
Yellow Tower itself 3310, 1560
Yellow control-panel puzzle: Easter Egg Hunt 3370, 1490
Yellow control-panel puzzle: Sound Check 3400, 1230
Yellow control-panel puzzle: Music Room 3200, 1260
Coordinates change per session

Big Walk's world is (at least partially) re-seeded between sessions — some walkthroughs note that puzzle positions and numbers can differ from one save to another. If a listed coordinate doesn't match your map, treat these as a strong starting point, not gospel.

Secret Locations & Hidden Rewards

Big Walk rewards exploration beyond the main path. The standout secrets:

The Shiny Secret Room (near the lighthouse)

The blue-lighthouse area hides a secret shiny room — accessible once the train is running (the train route passes near it). Inside you can get shiny — the paint/color change that pops the Big Makeover achievement. It's the same "get shiny" mechanic the community buzzes about: find the shiny material, paint your character, and the achievement unlocks.

The Easter Egg Hunt's secret orange tunnel

In the Yellow Tower's Easter Egg Hunt puzzle area (3370, 1490), there's a secret orange tunnel in the side of the mountain — one of the green puzzle pieces is only reachable by going through it. It's easy to miss if you stay at ground level.

Endgame remix secrets

After the first ending, the game offers a remixed endgame with seven remix challenges — a different arrangement of the island with new secrets to find. Replaying with a different group size also changes which puzzles and secrets are reachable.

The red barn — one of many landmarks visible on the island.

Mark your map as you go

Because coordinates can shift between sessions, the smartest habit is to mark new coordinate finds on your own paper map as you discover them — you'll build a personal atlas faster than any walkthrough can.
