After our ride on the funicular, we decided to catch a Bus back down to the Port area. We asked the shop keeper, and were going to buy a ticket, but didn't have to.
You see, our ticket from the funicular we still could use on the bus, as we had 90 minutes in which to use it. Great! Just look for AMT Buses, The Bus stops are marked clearly.
if you think to visit the museums listed in my "must see" tips and some more a wise idea is to buy the Museum +bus card :
%24hours: 8 € museums only and 9 euros Bus included. take in account that a single ticket will cost you 1 € for 90 minutes.
%threedays: 12 € museums only, 15€ bus pass included.
The best travel bargain , for the price of a bus ticket €1.20 you can travel for 90 minutes on any buses( not airport bus), metro and trains around Genoa as far as Nervi.although if you travel on the airport bus( cost €2.20) the ticket is also valid for the next 24 hours on any of the city transport.
Most of the city is easy to walk around, but, for travelling a little further afield the bus and regional train service is good. A day ticket, bought from the kiosks on almost all street corners, costs €2.58 and can be used on the bus, regional trains within the city, lifts and funiculars. A ticket for a single journey is €0.77 and valid for 90 minutes.
Bus from the airport couldn't be easier, just pay a couple of Euros, jump on... had no idea where I was going... jumped off at the train station... and walked from there... not far at all...
