Porto Hop-On Hop-Off Tour
In this tour you get to explore the city in one the best ways. Without having to worry about metro stations and buses, you go to all of the main attractions with the typical hop-on hop-off buses. You can leave the bus wherever you want to explore on your own, and then hop in again to go to another sight.
If you choose the upgrade you can also have the river cruise, which is something you definitely should not miss out on, and end the day at a wine tasting.
