An industrial symbol for Porto, the Luiz 1 Bridge in Porto is a twin-level arched bridge that connects the cities of Porto and nearby Villa Nova de Gaia. Walk over the Douro River from either the upper or lower levels of this metal bridge. Rising almost 45 metres in height, get an awesome view of the colourful Cais da Ribeira, Porto’s beautiful waterfront street, from the upper level of the bridge. Even better, pull up a chair at a café on this famous street for an almost-unobstructed view of the bridge. This is the best place to take a snap of the famous landmark and to people-watch for hours.
