A trail for pedestrians and bivycles that stretches along several kilometres, where there used to be the old railway between Valença and Monção. It is also very near the Minho river.

The wonderful historic centre of Valença is located inside the walls, from the old metal bridge to the landmark and several religious monuments, namely the Church if Colegiada of Saint Etêvão, the Church of Misericórdia and the Mother Church of Saint Maria dos Anjos. Valença firstly became important during the Middle Age as it was a passing point to the pilgrims heading for Santiago de Compostela. But it became known military wise. It was an important defensive stronghold, several times atacked by its Spanish neighbours. The fortress was built in the 18th century, inspired by the stronghold system of Vauban.
