The Castle of Sagunto offers a pleasant walk along its ancient walls. Leave your car and begin at the train station. You won't find any posted indications, so use the walls as a reference. After walking through the pleasant little town, there is a local trail that takes you around to the wall and the ancient Roman amphitheater, which has been renovated. The wall is stunning, and the walk very nice, though someone has littered part of the grounds. Once you reach the amphitheater, walk down to Sagunto and enjoy the streets and Cathedral, with a festive atmosphere.
