How do I travel from the cruise ship port in Naples to the Naples central train station?

Other than taking a taxi. What are safe streets to walk?

you get off the boat and mosey on over to the train station. if it's a tourist place, i'm sure it will be safe

I was in Naples port from cruise ship,and I think the better way to go in train station is on the taxi,the cost is around 15 euros also if you are 5 person,then depend were you mast go ?if you go in Sorrento o other town is better if you contact a private driver ,can I recommender Giuseppe he is from Sorrento and he make a good service see the web www.sorrentocoastdrivers.com

It's too far to walk, especially with a lot of luggage. Taxi is the only reasonable way. It should only be about 10 minutes by taxi (depending on Neapolitan traffic of course).

i am neapolitan. you can take a bus calle "alibus" from the port "beverello". this bus stops at the train station and at the airport
