One of Romania’s most dramatic corridors: eight kilometres of sheer 300 m limestone walls pinching to a single lane through the Gâtul Iadului, the Neck of Hell, before the red-tinged Red Lake.
From Lacu Roșu the DN12C enters the Cheile Bicazului canyon, carving through limestone cliffs that rise vertically from the road edge. A tunnel pierces the tightest headwall and at the Neck of Hell the overhanging rock narrows the sky to a slit; hairpins and bridges negotiate the canyon floor before it relaxes at Bicaz-Chei. Roadside bazaars add atmosphere and pedestrians.
