From Refugio Vega de Urriellu. On a Waymark Holidays trip led by Tony Rogers. We walked to Hda Arenera and on to Climb Torre de Cerredo (2648m), the highest peak of the Picos de Europa. The route is grade II but not really difficult, being rather loose and exposed. There were many others doing it, some taking wrong routes. We then went to Hda de Don Carlos. Some of us climbed Pico Boada, returning to the col and catching the others up on the way back to Refugio de Urriella.
