From the information panel on the route (580 m) starts a
leads to a pine forest. When you see a
cottage on top of the Piedra
Redonda (4 min) (610 m)., keep right and continue along a
path lined by
pines to a fork (21 min) (600 m), where you can take either of the paths.
The path to the right crosses the hill and the path to the left goes
Pico Babú and Pico de Duernes line the route on your right.
Soon the trees end and you walk through
pastures to a concrete
building gathering water from the fountains (37 min) (675 m). A little
bit further you come to the
track (40min) (670 m). At its beginning you
see on your right the highest peak of the Sierra del Sueve, the Pico
Pienzu with a cross on top of it. In the
plain of Bustacu you meet
herds of grazing cows and
horses. Among the horses you can spot little
black ones, descendants of horses left behind by Celts in the late Iron
The track narrows into a
path that ascends to the
pass of Beluenzu.
From its upper end you find a dry fountain (1h25min) (930 m), from where
you discern the cross on top of Pienzu. From the well you continue
uphill to the right along a grassy slope following a dry river bed. At
its end you bend right. A number of paths run on the steep and in some
places stony slope, but if you make for the crest of Sueve you stay on
the right path. Higher up the
route becomes a wide grassy
leads to the cross (2h10min) (1160 m). From the top of Pienzu you look
down to other peaks of
Sierra del Sueve and to the
Picos de Europa. If
the visibility is good you enjoy also nice sea views.
Return on the same way back to Fitu (4h10min).
