From Refugio de Vegarredonda. On a Waymark Holidays trip led by Tony Rogers. From the refugio we took the route marked on the map to Pico Cotalba. We continued to Torre de la Canal Vaquera. After Torre de la Canal Vaquera most scrambled up Poyón Sur. Some of us ascended El Requexón. We descended to Refugio de Vegarredonda.
