A very enjoyable climb. No steep inclines, a narrow but well-maintained road. The finish at the foot of Peña Montañesa has its charm.

Access is via forest tracks in good condition. Obviously, to reach 2000m it takes a little time but the reward is worth it: the views are magnificent over the valleys and peaks at 360 degrees. A delight !

This is the natural pass between the valleys of Chistau and Benasque. As such, it has been used for millennia and proof of this is the megalithic circle next to the track, which even then served to delimit border limits called "mugas".

The port of Arro leads to the Monastery of San Victorián, from the 6th century, considered the oldest in Spain. Legend has it that Saint Victorián arrived in the Pyrenees fleeing from earthly temptations. After a life as a hermit in the Cueva de la Espelunga and realizing great prodigies, he was appointed abbot of the monastery, which was originally called San Martín de Asán. Some time later, in the 11th century, the monastery took its name and was renamed San Victorian or San Beturián.
