The beach of Castelldefels covers all the coastal zone of the homonymous municipality. It forms part of an even more extensive sandbank that leads from the Port Ginesta, at the foot of the calcareous Garraf massif, until the mouth of the river Llobregat.
The beach is very well equipped with all the necessary services and facilities not only for the bathroom but also for leisure. The gastronomic offer is very interesting. A seafront promenade border the entire beach offering free parking.
Between the months of April to October the offer of activities is enormously varied. The strong winds that blow often are very adequate for the practice of windsurfing and kitesurfing.
