As not posible to ship the bycicle on media distance train in Bilbao towards Vitoria-Gazteis or Miranda de Ebro, you have to go up by road. Barazar and Urkiola are not usefull because heavy ramps and heavy traffic. Orduña not possible by heaviest ramp and to many cars oh weekend. I have found a good possibility by La Barrerilla from Orduña city. Is 300 mt lower than Orduña port and has fewer traffic.
