Castelldefels is a coastal town about twenty kilometres south west of Barcelona, favoured by international families for its long beach, larger homes, easy airport access and a British curriculum campus on the doorstep. It suits families who prioritise outdoor life, sport and space over a central city address, with a fast train and motorway link into Barcelona.
Castelldefels sits on the coast south west of Barcelona, between the city and the Garraf hills, built around a long sandy beach and a relaxed, outdoor town centre. For relocating families the draw is space and lifestyle: larger homes and gardens than central Barcelona, a beach for everyday life and sport, and quick access to the airport and the city by train and motorway. It is a natural base for families who want sun, sea and room to breathe within commuting distance of the city. To weigh it against the rest of the city, start from the Barcelona international schools hub, which sets out districts, curricula and the school landscape.
The town pairs naturally with the international schools of the south coast, which is a large part of why families settle here rather than in the city. Most choose Castelldefels for the combination of a family sized home, the beach and a specific school nearby, then rely on the train and a car for journeys into Barcelona and along the coast.
Castelldefels and the neighbouring Garraf coast are anchored by a British curriculum campus, with further options in Sitges and across south Barcelona. The named options below are established choices for families on this side of the city; confirm current places, fees and admissions directly with each school before applying.

Open the School FinderCastelldefels is well connected to Barcelona for a coastal town. Rodalies commuter trains on the R2 line run along the coast into the city in around thirty minutes, and the C-32 motorway gives a quick road route, with Barcelona El Prat airport only a short drive away, which suits families who travel often. Within the town, day to day life is walkable and bike friendly, particularly along the seafront.
For the school run, the British curriculum campus in Castelldefels keeps journeys short for many families, while those choosing schools further towards the city combine train, car and school bus. If a specific school is the priority, check its catchment and bus routes early, as the most popular campuses fill quickly and bus capacity is allocated ahead of term.
Housing in Castelldefels ranges from beachfront apartments to detached villas with pools in the hillside neighbourhoods above the town. Compared with central Barcelona, the town generally offers more space, gardens and outdoor living for the money, which is a large part of its appeal to families. Villas suit those wanting room and a pool, while apartments near the beach offer a lower entry point with the same coastal lifestyle.
