The oldest of the five Cinque Terre villages, Manarola is extremely popular for its wines. It also is somehow very crowded, so try and go a little early.
A Cinque Terre Card, available at the La Spezia train station for around 12 Euros grants you free rides on trains connecting the villages up to the town of Levanto. If in case you are not walking along the Blue Trail, Manarola is the second stop from La Spezia and the ride is approximately 11 minutes long. If you do not have a card, tickets can be bought for about 1.5 Euros at La Spezia or any of the other villages and require validation. The train mostly runs through tunnels but even the smallest glimpse of the sea is breath-taking.
