Climb Description

Puerto Arnicio is a quiet and relative unknown climb. The climb really begins 15km earlier from the town of Infiesto; however, the first part is so gentle that it seems wrong to include it in the overall statistics. It is fairly picturesque, but is mostly in forest until it all spectacularly opens up at the top of the pass.

The road is fantastically quiet and we recommend climbing it if you are in the area, but the road surface is annoying on the descent and reduces the overall rating to ***.

Puerto de Arnicio usually open year-round; however, short-term closures due to snow are possible during the winter.

The scenery is pleasant rather than spectacular





Roads & Traffic

The road is in quite poor condition. It doesn't have many pot-holes, but the surface is very rough bumpy - something which is particularly noticeable when descending either side.

There is very little traffic on this climb.




Alternative Routes

Puerto de Arnicio can also be approached from the south, starting in Campo de Caso. It is quite rolling from this side with stretches of downhill and flatter periods, making it difficult to really categorize it as a climb. The surface is equally rough on this side.
