From Bilbao we will go to Vitoria-Gasteiz where we will take a guided walking tour of the old town. We will then drive through the so-called "Valle Salado" (Salt Valley) where we will stop to visit the Añana salt mine, one of the oldest in the world. Once the guided tour is over, we will make a short stop in Orduña to visit its beautiful historical centre. Afterwards, we will cross the beautiful natural landscape of the Ayala Valley to regain our strength with lunch (included) in a beautiful convent that has been converted into a restaurant in Balmaseda. Finally, we will visit Bizkaia Bridge, the first transporter bridge built in the world with a metal structure which we will cross by nacelle.
