How late at night do the trains run in and out of Cinque Terra and how safe are they @ night?
According to the timetables at www.bahn.de, the last train leaves Monterosso at 23:50 and arrives in Riomaggiore at 00:12. Going the other way, the last train leaves Riomaggiore at 00:59 and arrives at Monterosso at 01:16. If you want to know how late you can get from someplace like La Spezia to one of the Cinque Terre towns, the DB timetables will tell you that, too. Click on "Internat. Guests" for English.
