Turkey’s most extreme mountain road climbs 13 consecutive guardrail-free hairpins through Mount Soğanlı, with sheer drops of hundreds of metres and gradients hitting 17%.
The D915 runs from the Black Sea town of Of across the Pontic Mountains to Bayburt, crossing the Soğanlı Pass at 2,330 m. Its centrepiece is the Derebaşı section near Çaykara: 13 ferociously tight switchbacks compressed into roughly 5 km with no barrier between the road and a sheer face. The surface is mixed asphalt and gravel and is closed for around eight months a year by snow.
