(S/E) Continue on foot in the opposite direction to Casa de Olivan.
(1) Take the steep path North to Las Clavijas de Salarons (signposted). When you reach the Gallinero torrent (Barranco in Spanish), stay on its left bank and continue northwards on a steep ascent.
(2) Leave the Clavijas path at the crossroads to take the very good Faja Racon path on the horizontal right.
Skirt the steep cliffs of Punta Gallinero, then Saco Ciego, to reach the rocky barrier of Circo de Cotatuero.
(3) Begin the descent of the right bank of the Torrent de Cotatuero on a good path that joins the track leading to the bottom of the Rio Arazas valley.
(4) Turn right onto this track, which leads back to the Pradera car park (S/E).
