Sant Andreu de Llavaneres is directly on the R1 Rodalies (commuter train) line from Barcelona Sants and Passeig de Gràcia. The journey takes around 45 minutes to an hour depending on service. Trains run frequently throughout the day. The station is close to both the beach and the town centre.
By car, the town is about 35km north of Barcelona on the C-32 motorway (toll) or the N-II coastal road (slower but more scenic). Parking is generally available in the town.
