Complete guide to holidays in Castelldefels (2026)
Everything you need to know to plan your Castelldefels holiday: when to go, where to stay, what to see, budget and local tips.
Why Castelldefels is the perfect destination
Castelldefels is that rare place that has it all: 5 km of beach, mountains behind, Barcelona 20 minutes away and an airport 10 minutes away. It's not an artificial resort or an overcrowded town. It's a real city of 70,000 people that lives facing the sea.
This guide covers absolutely everything you need to know to plan your holiday.
When to go
High season (June-September)
The classic choice. Temperatures of 25-32°C, water at 24°C, everything open. It's the liveliest time but also the most expensive and crowded. If coming in August, book months in advance.
Mid season (April-May, October)
Our recommendation. Temperatures of 18-25°C, perfect for beach and activities. Fewer people, lower prices and Garraf at its best.
Low season (November-March)
For those seeking absolute tranquillity. Temperatures of 10-16°C, empty beaches, incredible sunsets. Prices up to 50% lower. Ideal for remote working or long stays.
Where to stay: Castelldefels areas
Beach area
Beachfront or 2-3 streets from the sea. Ideal if the beach is your priority. Apartments usually have terraces and many have sea views. It's the most expensive area.
Centre area
Castelldefels' urban centre. Close to shops, restaurants, market and train station. Well connected to the beach (10-15 min walk). More affordable prices.
Golf area
Between the golf course and the beach. Quiet streets, residential atmosphere. Perfect for golfers or families seeking calm. 10 min from the beach.
Gavà Mar area
On the southern border, next to Gavà. Quieter beach, more exclusive atmosphere. Good option if you want maximum tranquillity.

- Sun protection: the Mediterranean sun is stronger than it seems, even in October
- Money: cards accepted everywhere. Little need for cash
- Language: Spanish and Catalan. In the tourist area English is understood without issue
