The twistiest famous roads, ranked
Which famous road has the most corners? Turini’s pace-note engine calls every bend of the 61 famous driving roads on this site, so we counted them. Amalfi Coast Road comes first with 19.9 corners a mile, Col de Turini second with 19.3. At the other end, the most flowing are Atlantic Ocean Road, Glencoe and Pacific Coast Highway (Big Sur).
Ranked by corners per mile
Every corner Turini calls on the route on each road’s page, divided by its length. Hairpins are the turns that double back on themselves.

How we counted
Turini reads each road from OpenStreetMap and terrain data and calls it the way a rally co-driver would: a direction and a grade from 1 (tightest) to 6 (nearly straight) for every corner, plus hairpins and square corners. Each one counts once here. Crests, dips, bridges and narrow sections are called too, but they are not corners, so they don’t count.
The counts are for the route shown on each road’s page, which is often one side of a pass or one stretch of a long road, so a short, dense stretch can rank above a longer road that has more corners in all. Hairpins are counted where the road really doubles back, so they can differ from the numbered signs on some passes. The engine is the same one you hear in the car, and the numbers change only when the map or the engine does.

Questions
What is the twistiest famous road?
Of the 61 famous roads on Turini, Amalfi Coast Road has the most corners for its length: 19.9 a mile (12.4 a kilometre) on the route on its page. Col de Turini is next with 19.3 a mile. Vršič Pass has the most hairpins, 54.
How are the corners counted?
Turini’s pace-note engine reads each road from OpenStreetMap and elevation data and calls it the way a rally co-driver would. Every graded corner (1 to 6), hairpin and square corner counts once; crests, dips, bridges and the like don’t count. The total is divided by the length of the route on the road’s page.
Is the twistiest road the best one to drive?
Not necessarily. Atlantic Ocean Road, last here with 2 corners a mile, is famous for other reasons. A dense road is slow and tiring; many of the great drives mix fast bends with views. Use the list to know what to expect.
What the numbers mean
Each corner is called as a direction and a grade from 1 (tightest) to 6 (nearly straight). Hairpins are the turns that double back on themselves. The counts come straight from Turini’s engine reading the OpenStreetMap road, the same calls you hear in the car. The climb (↑) is the height gained over the route, from terrain data. New to it?

Always drive within the law, the conditions and what you can see. Turini tells you what the map says; the road is what counts.
