Porto is hilly, which means there are a lot of lookout points through the city.  This particular one was at the Jardins do Palácio de Cristal.  On the left of the main park is a path that takes you down to these smaller gardens overlooking the Douro river and the Vila Nova de Gaia side. These secret gardens are pockets of serenity within the city, surrounded by flowers, large shaded trees, and amazing views.  Once in awhile you’ll hear a sharp cry, but don’t be disturbed, it’s just one of the peacocks signaling a mate.
