Earth Sandwich

Earth Sandwich / Corridors

Corridor guides · 10 corridors

Where on Earth you can make an Earth sandwich.

An Earth sandwich needs dry land at both ends, and most land has ocean on its far side. What is left comes in a handful of corridors, pairs of regions that sit exactly opposite each other. Each has a guide: where every city on both sides lands, the towns that are each other’s antipode, the highest pairs, and how to time the bread. For the whole planet at once, see the map of where it’s possible; for any single spot, the live map.

Spain & Portugal ↔ New Zealand

Central Spain sits under New Zealand’s North Island: the most famous antipodes, with towns at both ends.

China & Mongolia ↔ Argentina & Chile

The biggest corridor by far: a billion people in eastern China and Mongolia live opposite Argentina and Chile.

975.0 million people in China live with land opposite · 3 town twins · top bonus +6,160 m
