Caminhos do Romântico
Time Out says
It’s an important opportunity to know Porto’s historic trails. These offer unique cultural and historic routes, allowing you to choose from five trails: Romantic Porto (“Porto Romântico”), Taking Advantage of the Water (“Aproveitamento da Água”), Rural Archaeology (“Arqueologia Rural”), Industrial and “From Gólgota to Massarelos” (“Do Gólgota to Massarelos”). All of these trails have informative signs. You can go alone or as part of a small group, on foot or by bicycle. But if you join a group of 10 you get a guided tour that will explain you the importance of each monument or stopping place. Book in advance and enjoy that free two-hour walk.
