How steep is the road to Col de Bostmendieta?

Is the road to Col de Bostmendieta paved?
The road is paved, but the surface is in poor condition due to high-altitude weather and lack of maintenance. The narrow road is often littered with stones from the side slopes. In the upper sectors, the asphalt has disintegrated in many spots, leaving patches of gravel where wheels can spin, especially on the 12% ramps. On the final part of the 8.6 km ascent, the asphalt is heavily degraded, with potholes and loose gravel on the surface that can reduce tire grip during the climb.
How challenging is the road to Col de Bostmendieta?
The route features many curves and four tight hairpins with no safety barriers. The narrowness of the road means there is very little room to pass oncoming vehicles, often requiring one driver to stop on the edge of the slope. In wet weather, the combination of old asphalt, loose gravel, and 12% gradients makes the surface extremely slippery.
