Castelldefels and Gavà are the northern end of the Costa del Garraf, in the Baix Llobregat comarca just south-west of Barcelona and its airport: one unbroken sandbank from Port Ginesta, at the foot of the Garraf massif, to the Murtra wetland on the edge of the Llobregat delta. Castelldefels has about 4.8 km of beach and Gavà between 2.7 and 3.8 km, depending on the source, both with a seafront promenade, dunes and full services, and the Rodalies R2 Sud train links the towns with Barcelona (Catalunya.com). Behind the beaches are a hilltop castle, the oldest mines with galleries in Europe and the limestone paths of the Garraf Natural Park.

Towns and villagesTowns and villages
From west to east, from the Garraf hills towards Barcelona and the Llobregat delta.
Les Botigues de Sitges and Port Ginesta
The western end of the stretch belongs to the municipality of Sitges but adjoins Castelldefels. Its beach, Les Botigues, is 1,415 m of sand about 100 m wide, with parking, beach bars and apartment blocks behind it (spain.info). At its western tip lies Port Ginesta, opened in 1986 and enlarged in 2007 where the long beach meets the Garraf massif (Catalunya.com). The marina has 1,180 moorings and 75 businesses on site, and calls itself the largest leisure marina in Spain for mooring rental and nautical services (Port Ginesta). Restaurants, bars and nautical shops make it busy at all hours in summer. Beyond the port the coast turns rocky; the village of Garraf and Sitges are covered in our Garraf and Sitges guide.
Castelldefels: the town and the castle
Castelldefels lies between the delta wetlands and the limestone of the Garraf Natural Park, which takes in part of its territory; hills such as the Fanxó reach about 300 m (Catalunya.com). The name, recorded as Castrum Fidelis in 967, comes from the castle on its hill. Castelldefels Castle was built in the 10th century to defend the church of Santa Maria, and the views from it reach the Garraf, Collserola, Montjuïc, the delta and the coastline. Twelve 16th-century watchtowers, built to warn of pirate raids, still stand around the town: the Torre Barona is in the grounds of a hotel and the Torre de Can Gomar houses the Casa de Cultura. More than twenty sculptures are spread through the streets. The town grew with the Barcelona–Vilanova railway in the 19th century and tripled its population in the 1960s, when it became a tourist town.
Castelldefels: the seafront
Behind the beach lie wide streets with palm trees and plenty of shops and places to go out, with their own station, Platja de Castelldefels, near the western end of the beach. The 4.8 km beach is divided into the Baixador, Lluminetes and Pineda sections (Catalan Wikipedia), with a promenade, a bike lane and free parking along its whole length (Catalunya.com). The Club Nàutic and several sailing schools work from the sand, and the Canal Olímpic de Catalunya, built for the canoeing events of the 1992 Barcelona Olympics, lies just inland. Mid-July brings the Festes del Mar, with habaneras, beach volleyball and fireworks that re-enact a pirate landing. See our Castelldefels Beach guide.
Gavà: the old town and the hills
Gavà sits between the coastal hills and the sea, near the mouth of the Llobregat; the north-west of the municipality is in the Garraf Natural Park, with heights above 400 m, and the boundary with Viladecans includes the protected ponds of the delta (Catalunya.com). In town, Can Rosés is a farmhouse of 1326 with a large sundial, and Can Tintorer, a 15th-century masia, houses the museum of the Gavà Mines, the oldest mining complex with galleries in Europe, dug about 6,000 years ago for green variscite used in jewellery (Catalunya.com). Up in the hills stand the ruins of Eramprunyà castle, built in 957, reached on a path from the 13th-century chapel of Bruguers. The first factory, the Roca sanitaryware works, arrived in 1914.
Gavà Mar
Gavà Mar is the town’s seaside district, and the beach lies right behind it. The beach, also called La Pineda after the pine wood that runs down to the sand, is fine sand with a very gentle slope, play areas, a beach library and amphibious chairs (Catalunya.com). The promenade, which winds between dunes and pines, won the FAD architecture prize in 1995 (Catalunya.com). East of the beach, the Estany de la Murtra is a wetland on the route of thousands of migratory birds, and the campsite HolaCamp Barcelona lies close by. Beyond it, Viladecans and El Prat belong to the protected Llobregat delta. See our Gavà Beach guide.
Beaches and coves
There are no coves on this stretch: it is one long, straight sandbank built from Llobregat sediment, open to the wind, with dunes protected behind fences. Lengths and services are from spain.info and Catalunya.com.
Castelldefels Beach
4,840 m of golden sand about 90 m wide, with sunshade and lounger hire, water-sports hire, toilets, showers, a sailing club and a tourist office; calm but often windy water and high occupancy (spain.info). A train station stands at its western end.

Nature: the Garraf hills and the delta
The Garraf Natural Park covers more than 12,000 hectares of white limestone, scrub with dwarf fan palms, holm oaks and Aleppo pines, home to eagles, falcons and greater horseshoe bats (Catalunya.com). From this side, marked routes include the walk from Cal Ganxo to La Morella in Castelldefels and the Camí d’Eramprunyà in Gavà; the Fondo de Vallgrassa route shows the sinkholes where water drains into the rock (Catalunya.com). At the other end, the Llobregat delta has four bird hides and eight viewing towers, with paths for walkers and cyclists (Catalunya.com). See our Garraf Massif guide.
History: castle, towers and Neolithic mines
Start at Castelldefels Castle, where Catalunya.com suggests a one-hour guided tour, then look for the watchtowers in town (Catalunya.com). In Gavà, the archaeological park of the Gavà Mines shows galleries worked for more than a thousand years, and Can Lluc, a house of 1799, is the seat of the Museu de Gavà (Catalunya.com). Inside the park, the Palau Novellà, built in 1890 in the style of the returning emigrants, is the seat of the first Buddhist monastery in Catalonia, with a large collection of Tibetan art (Catalunya.com).
Water sports and the Olympic canal
The frequent wind makes Castelldefels a centre for windsurfing and kitesurfing (Catalunya.com). The Canal Olímpic de Catalunya is a 1,200 m freshwater canal, 130 m wide and 4 m deep, fed by the Llobregat water table; non-members pay an entry fee and can hire rowing boats, kayaks and canoes, and motorboats are not allowed. It also has a pitch-and-putt course, a volleyball pitch, pools and a cycling track, and is fully adapted for people with reduced mobility (Catalunya.com). At Port Ginesta you can hire a boat.
Food and festivals
Gavà holds its asparagus fair, the Fira dels Espàrrecs, at the end of April, a half marathon between Gavà and Castelldefels in February, and its main festival for Sant Pere on 29 June, which opens with fireworks on the beach (Catalunya.com). Castelldefels has the Sant Ponç food and craft fair at the end of May, the Festes del Mar in mid-July and its Festa Major and International Dance Festival in mid-August (Catalunya.com). Catalunya.com also names Castelldefels as a reference for seafood cooking, and both promenades have beach bars and restaurants.
