Transfer from Florence to Naples

Duplicate question. The same question with answer is running under Transportation.

Train is certainly the easiest, there is a fast main line that goes that route, going through Rome. Check out www.trenitalia.com it is the Italian Train site, you can put in your dates and times and see the options. If you get nothing for the date needed, it may be that schedules are not loaded yet, so put in a similar day out a couple weeks, the schedule will not change much. You options will be the faster more expensive trains, moderate priced intercity trains, and then the cheapest and slowest regional trains. The best choice is the one that fits your budget and schedule.

Thanks
