If you want to get off the bike take the cable car up to fuente de and walk back down- stunning views although we did it in fog and snow! The Cares Gorge is pretty spectacular. But better than both is a day spent in the Ordessa Canyon in the Pyrenees. Accomodation and camping available in Torla. You can link the picos and Pyrenees up with a visit to the Bardenas Reales near Tudela. For roads it has to be the N260.
