Discover Porto's historic attractions, beaches and port on a City Sightseeing hop-on hop-off bus tour! The 2-day unlimited travel ticket can be used on two routes, one that journeys through the city center and the other through the neighboring coastal towns of Matosinhos and Vila Nova de Gaia. See all of the sights with 360-degree views on the open-top double-decker bus, and then hop on and off whenever you like to explore on your own.
