Climb Description

Alto de la Tornería is a beautiful climb in the Asturias region. This side begins at a junction with the AS-115 road and heads west up to the scenic pass. The road is very quiet as you pass through farmland and open countryside.

The green scenery and views make it very enjoyable, and the gradients are respectable at times, but never too challenging. Like its neighbour Alto del Torno, this is one of the many relatively unknown climbs in Asturias, that are absolutely brilliant for cycling. If you are in the area, make sure you climb it from either side!

The area around the climb - in the particular the village of El Mazuco - was also a major center of resistance during the Spanish Civil War. Opponents of the fascist dictator, General Franco, hid out in these mountains under intense pressure. The first known use of carpet bombing took place here in 1937, carried out by the German Condor Legion. But despite a lot of destruction, the Republicans resisted the attack and held onto the important mountain pass for several more months.

Alto de la Tornería is usually open throughout the year.
