The old road “Camino de la Val Estrecha” connects via a tunnel to the N-330a at Sabiñánigo (Samianigo, in Aragonés and Catalán), where that national road then becomes the Eje Pirenaico (N-260), the northernmost East-West thoroughfare in Spain and a route I had planned to roughly follow over the next days and nights.
