Área de Serviço de São Mamede Coronado
We didnt have good luck and actually would disadvise that place as people running the station threatened to call the cops,and even though it is busy,not many trucks and mainy people going to Braga.―Jorgegalicia, December 2012
Very good spot to hitchhike north (to Braga, to Galizia [Vigo, Santiago]...). Take the train to So Frutuoso and walk 800m to the gas station in the A3. You'll have to look for the good place to climb over the fence. Make sure no one sees you!
