NA-170 — Oiartzun to Elizondo

Spain · measured from OpenStreetMap geometry

616Corners
12Miles
51.3Per mile

NA-170 runs 12 miles between Oiartzun and Elizondo. We counted 616 corners along it, which works out at 51.3 a mile — corner after corner with no let-up. It runs past mountain peaks, a river, a mountain pass and forest. That is busier than two thirds of the roads we have measured in Spain, where the median is 47.4 a mile.

Ridden together with GI-2631 and GI-3631 it makes about 18 more miles of the same kind of road.

How we measured it

Corner counts come from the road's own geometry in OpenStreetMap, not from ratings or votes. Every bend above a threshold of curvature is counted once, so two roads can be compared directly. Nothing here is crowdsourced and nobody paid to appear.
