The local build organizes the island into numbered zone labels. This index is a starting point for exploration—not an official map, and not a walkthrough. Zone names are internal labels, and in-game boundaries are unverified.

How big is the Big Walk map?
No official map size is published. The release build’s zone labels suggest a large island
organized into regions that run from an intro valley in the west to a far-north ending area,
with the Peak at the centre and rivers crossing the south. The labels reach 99
(Secret Zone), though numbered gaps exist and do not by themselves mean anything.
These names come from scene and terrain labels in the locally installed macOS Steam build
(v1.4.7). They are evidence that the zones exist, not proof of exact borders, official
names, or what happens in each area.

What the labels hint at
The Peak matches the reported Big Climb achievement (“Reach the highest point”) and splits into centre, north, south, east, and west labels.
Goodbye Gate and Far North Ending Area line up with the reported ending achievements Big Goodbye and Big Game.
Vereker appears repeatedly (North of Vereker, Vereker Coast Point, Vereker Backpack Pavilion), suggesting a named landmark in the north.
Secret Zone (99) is the only double-digit label after the terrain labels; what it contains is not known.
Green, Blue, Black, and Yellow tower ridges point to landmark towers spread across the island.
Treat every hint above as a lead, not a claim. Exact locations, routes, and puzzle roles
need in-game verification before they become guide content.
Evidence note: zone labels are derived from scene, terrain, and mesh references in the
locally installed macOS Steam build (v1.4.7) on August 5, 2026. They are not
developer-authored descriptions. Send a reproducible observation—platform, group size,
zone, and steps—to help turn these entries into tested guides.
