Valença lies on the main Vigo–Porto railway line, and trains stop here regularly. From Porto, the journey takes about two hours. From Vigo in Spain, it is under an hour. The station is at the bottom of the hill below the fortress.
By car, Valença sits on the A3 motorway from Porto to the Spanish border, making it an easy stop on a road trip along the Minho valley. From Porto, the drive takes just over an hour. Crossing into Spain is seamless — the bridge connects directly to Tui and the Spanish road network.
