As mentioned before Livorno is not the most charming town of Tuscany but it has a few interesting attractions for the cruise ship passenger that has visited the main attractions of Tuscany or for those that just want to spend a relaxing day in port without all the traveling involved to explore Florence, Siena or Lucca. Exploring the city center of Livorno on your own is easy and, being absolutely flat, physically undemanding.
A few highlights like the Museo Civico Giovanni Fattori, the Acquario Comunale Giacinto Cestoni and the Passeggiata Mascagni are not at walking distance from the city center but are close enough and easy to reach. However, public transportation is very easy to navigate.
Bus# 1 runs between Piazza Grande and Ardenza along Viale Italia and has stops close to the Aquarium and next to Passeggiata Mascagni, both at walking distance to the Museum Fattori. Just make sure that you buy bus tickets at the Newsstands on the Piazza Grande (strongly advisable to buy two tickets so that you don't have to look for another kiosk on the way back). Bus #1 to the Ardenza stops in front of McDonalds - the opposite side of the Cathedral - heading right (West) when facing the Duomo.
Another option is to get on the Hop-On Hop-Off City Sightseeing Bus, which have been operating since 2009 and tour the city with multilingual audio guides; this has become an easy way to explore the highlights. The Hop-On Hop-Off Buses have stops next to major highlights and also to other attractions like the Natural History Museum, the Modigliani's House, most churches, and landmarks.
Cruising the canals of Livorno has become another attractive way of exploring the city as it offers a unique perspective of the city - one of the highlights is the stretch under the Piazza Republica, which is considered one of the largest bridges in Europe. It is also an interesting way of seeing both the Fortezza Nuova and the Fortezza Vecchia (the Old and New Forts). Wherever, and whatever, the cruise ship passenger decides to explore always keep in mind that Livorno was heavily bombed during WWII and many areas clearly show the 'scares' of devastation.
