There's nothing more pleasant than kicking back on the banks of a river and watching the water as it travels downstream. Why not pack a picnic lunch and spend a quiet afternoon at River Douro?
This flowing body of water has free entry, so you can have a great time without grabbing for your wallet. However, River Douro isn't the only worthwhile sight in and around the riverside area of Sao Nicolau. With Sandeman Cellars, Casa da Musica and Porto Cathedral close by, you may want to extend your stay.
