On any of its slopes, that of Boltaña and that of Guarguera, the port of Serrablo is a long port, more than 12 kilometers long. It is more irregular from La Guarguera, due to the continuous ups and downs of its final kilometres, and with a more classic profile from Boltaña. Even so, the Boltaña slope alternates kilometers with a gradient of up to 6% with others of authentic rest. The road is very quiet, with very little traffic, with good views of the natural park of the Sierra and the Guara canyons on the south side and the national park of Ordesa and Monte Perdido on the north side.

At the level of the bridge, the Ara river forms beautiful natural pools. It is tempting to go swimming there.
