Roads & Traffic

The road surface is mixed. It is in very good condition on the lower part of the climb, but has become cracked and bumpy in places closer to the summit. Towards the top of the climb there are also sections with a significant amount of loose gravel on the road.

There is little traffic throughout the climb.

Climb Description

Puerto de Marabio

Puerto de Marabio is far from the most well known climb in this part of Asturias. However, it is an enjoyable ride that can be included on a longer circular route. The last part of the climb, once you have passed through Tameza is very open and offers fantastic views across the rolling countryside.

Puerto Marabio is nominally open throughout the year. Short term closures are possible in winter due to localized snow.

Other Sides

Puerto de Marabio can also be climbed from the south - starting in Entrago. This is a shorter and more direct climb.
