As there is a railway station in every village, the train is certainly the most efficient way to move. In high season, from april to november, during the day, there is a train every 20 minutes.   The adult price is 5 euros for single trip or 18,20 euros for unlimited daily travels with the Cinque Terre Card - 33,00 euros 2 days - 47,00 euros 3 day.

Cinque Terre Express way: 

La Spezia -> Riomaggiore - Manarola - Corniglia - Vernazza - Monterosso <- Levanto
