La Clota's three-day-long festa major, the main festival, is bursting with all kinds of activities. The events, aimed a wide range of the public, are centred around Avinguda del Marquès de Castellbell.

The rich and varied popular culture of the neighbourhood also plays a very important role in the festival. All the local groups join together for the cercavila d'inauguració, the opening procession.

The festa major, the main festival, which is held over two weekends, is a good example of the strong associations and organisations that are deeply involved in arranging all kinds of events.
