This is definitely worth getting to see the sites in Porto, we bought this for 40 euros for two days, there is no way you can do it in 1 day, this stops of at several stops, and you can pick up from any stop, there is some really lovely architecture, beaches, zoo, churches, sea life, to name just a few.

I purchased a premium package, activating the tourist bus one day and I could not use this service on the second day because they are consecutive and this second day I had an excursion scheduled. I also had no opportunity to use the tram, in this case due to lack of time. The audio of the bus a little low.

We take advantage of the 3, although the funicular is very simple and short the section. The tram was very nice and the most interesting thing was the bus, to know places and history. There were some bus seats where the headphone system did not work and when the bus was full, you could not change seats.
