Legend says Finn McCool — Fionn mac Cumhaill — built this road stone by stone across the North Channel to challenge his Scottish rival Benandonner. Forty thousand interlocking hexagonal columns, each one a stepping stone across the Irish Sea. The geology tells a different story: volcanic eruptions sixty million years ago, lava cooling and contracting into near-perfect hexagons. But here is what both stories agree on — the same formation emerges from the sea on the Isle of Staffa in Scotland, exactly as the myth describes. The road still runs. Whether Finn built it or a volcano did, the effect is the same: you stand here and feel the world tilt toward the impossible.
