Find the cheapest holidays to Castelldefels from UK airports. Updated daily.







Castelldefels is a relaxed coastal resort just south-west of Barcelona, offering a practical mix of beach time, good food and easy sightseeing. It suits holidaymakers who want the freedom to enjoy the Catalan coast without staying in the middle of a busy city, while still being close enough to visit Barcelona by train.
The resort’s main draw is its long, wide sandy beach, which stretches for several kilometres and has plenty of space compared with many busier urban beaches. The seafront is lined with cafés, restaurants and beach bars, with a promenade that is ideal for a gentle walk, cycle or evening drink. In summer, the beach has a livelier feel, while outside peak season it is generally calmer and popular with locals.
Eating out in Castelldefels is easy and varied. Along the beachfront you will find seafood restaurants, tapas spots, rice dishes and relaxed places for lunch with sea views. The town centre, set slightly inland, has a more local atmosphere, with bakeries, bars and everyday restaurants. Nightlife is present but not overwhelming; expect beach bars, late dinners and casual drinks rather than a full-on party resort.
There is more to Castelldefels than the seafront. Castelldefels Castle sits above the town and gives a sense of the area’s history, while the nearby Garraf Natural Park is useful for walking, viewpoints and a change of scenery away from the coast. The Canal Olímpic de Catalunya, built for the Barcelona 1992 Olympic Games, offers watersports and outdoor activities, depending on the season and conditions.
One of Castelldefels’ biggest advantages is its location. Barcelona is within easy reach by public transport, making day trips to the Gothic Quarter, Sagrada Família, museums and shopping straightforward. The resort is also close to Barcelona airport, which can make transfers relatively simple for UK travellers. Overall, Castelldefels works well for a beach-based holiday with good restaurants, a laid-back atmosphere and excellent access to Barcelona and the wider Catalan coast.
