The best way to reach Manarola by car is from La Spezia at the A12 motorway exit (La Spezia - Santo Stefano Magra) and then continue towards the seafront of La Spezia and take the Cinque Terre coastal road (SP 370). After Riomaggiore there is the crossroads that go down to Manarola.
Along the state road to Manarola you can park but pay attention to the prohibitions. At the entrance of the village there is a paid parking with limited spaces, shuttle service that runs every 30 minutes (1.50 Euros).
Parking in the Cinque Terre area is quite limited, we recommend the use of the train (Trains page).
