Sur Pisón

Follow your nose up through town past the fuente (water fountain), and towards the tower.
Descent:
From the summit, walk climber’s right until you see a metal cable. Follow this to a rap station. There’s a midway anchor if you’re on a single rope.
(From here, there’s a set of rings directly below, taking you into the Cirque de Verano. We didn’t check it out, because we’re on a single 80m, but if someone sniffs it out be sure to update.)
Otherwise, follow the cable down for a couple metres to another rap station that drops you into a gully.
Another cable leads to another rap station. From here’s there’s a bunch of steep scrambling down the gully guided by more cables, before ending in a semi free-hanging rappel. An 80m gets you to the ground, otherwise there’s midway anchors (you might need to bounce a bit).
Back on terra firma, follow your nose back to the refugio for a well earned drink
