This guidebook describes 80 classic multi-pitch rock climbing routes spread across the central massif of the Picos de Europa, including the Picu Urriellu. The guidebook covers 9 different faces across the Central Massif of the Picos de Europa.  Due to the different orientation of these walls, it is possible to choose a multi-pitch route on these really beautiful and imposing peaks depending on the season and the desired orientation of the sun.
