The town's main activity is tourism due to its three long golden beaches of Platja de Llevant, Platja de les Dunes and Platja de les Caletes, all of which are backed by a line of modern well-equipped hotels.
Further inland there are still a number of farms where the traditional agricultural activity continues and there are quite a few chapels scattered around the municipality, including the Chapel of Santa Susana from which the town takes its name.
Set back from the coastline, you'll see many defence towers which date back to the time when this part of the Catalan coast was under attack from Moorish pirates.
By Road: The main N-II road along the coast passes through the municipality.
By Rail: Santa Susana has a station on the RENFE Rodalies R1 Line, which goes from Barcelona to Maçanet-Massanes.
If you understand some Catalan, you can find up to date news about Dosrius on the Ajuntament de Santa Susana Website.
