Llobregat Delta nature reserves (El Prat and Viladecans)

The Llobregat Delta nature reserves are the protected lagoons, marshes, pinewoods and beaches left on the flat river plain south-west of Barcelona, right beside Barcelona-El Prat airport. Catalunya.com puts them about 2 km from the airport and 12 km from the centre of Barcelona, with buses L94 and L95 from Ronda Universitat and access by the C-31 coast motorway. Entry is free during opening hours. They suit birdwatchers, walkers and travellers with a few hours before a flight; skip them if you want wild, quiet country, because the airport, motorways and port are right next door.

Quick facts

• Names: Espais Naturals del Delta del Llobregat (Catalan), Espacios Naturales del Delta del Llobregat (Spanish); in English often just the Llobregat Delta. The best-known reserves are El Remolar-Filipines in Viladecans and the river areas of Cal Tet and Ca l’Arana in El Prat de Llobregat.
• Where: the coastal strip of El Prat de Llobregat, Viladecans, Sant Boi de Llobregat and Gavà, Baix Llobregat, Barcelona province. The airport itself lies inside the delta (Catalunya.com).
• Coordinates: 41.2813, 2.0706 (Estany del Remolar, the Remolar lagoon; OpenStreetMap).
• Protection: declared in 1987; a Natura 2000 Special Protection Area for birds (ZEPA) and Special Area of Conservation. Catalunya.com gives the protected area as 969 ha; Catalan Wikipedia says the bird protection area was enlarged in 2024.
• Birds: more than 360 species recorded, one of the highest totals on the Iberian Peninsula (Catalunya.com).
• Entry: free during opening hours; guided tours and group visits on 934 793 201 (Catalunya.com, checked November 2026).

Access and parking

From the airport: the reserves start about 2 km from the terminals; on OpenStreetMap the Remolar lagoon is about 1 km in a straight line from the Terminal 1 car parks. We could not confirm a walking route, so plan on a bus or taxi.

By bus from Barcelona: Catalunya.com lists lines L94 and L95 from Ronda Universitat in central Barcelona. We did not check stop names or timetables; look them up before you go.

By car: take the C-31 Castelldefels motorway towards the airport. Catalunya.com gives the entrance to the Remolar-Filipines area at kilometre 11 of the C-31. The C-31 cuts the old Filipines marsh in two: Filipines Nord lies north of the road and El Remolar-Filipines, the part you visit, south of it (Catalan Wikipedia). The river areas of Cal Tet and Ca l’Arana are reached from El Prat, along the Camí de Cal Tet. We could not confirm parking capacity at either site.

What to expect

The delta is a flat plain of fields, pinewoods, wetlands, lagoons and beaches. Catalunya.com describes the plain as stretching between the Garraf massif and Montjuïc, up to the narrow pass of Sant Andreu de la Barca, and says it is young: it appeared in Roman times and kept growing until the 19th century. Old river mouths left the coastal lagoons; Catalan Wikipedia says only La Ricarda and El Remolar still keep a natural landscape, and that together the delta’s wetlands are the third most important in Catalonia.

The protected land is split into separate pieces, each with paths, hides and towers:

• El Remolar-Filipines and Viladecans beach (188 ha): the Remolar lagoon, the Filipines marshes, the Sant Climent stream, the Cal Francès pinewood and part of Viladecans beach. Grey herons, cormorants, ducks and lapwings are easy to see here (Catalunya.com).
• The natural areas of the Llobregat river (about 145 ha), on the right bank of the last stretch of the river: reed beds, pinewoods, beach and the lagoons of Cal Tet and Ca l’Arana, “a miniature delta” in Catalunya.com’s words.
• The Can Camins pinewood and El Prat beach (48 ha): stone pines on old dunes behind the beach.
• Can Dimoni ponds (31 ha): three small lakes among the farmland of Sant Boi, known for roosting herons and cattle egrets.
• La Murtra pond and La Maiola pinewood, between Viladecans and Gavà: little bittern, kingfisher and little ringed plover live around the pond.

The landscape has been reshaped many times. In 2004, to enlarge the port of Barcelona, the last 3.5 km of the river were moved 2.5 km to the south; the new Cal Tet lagoon and aquifer recharge ponds were built as compensation (Catalan Wikipedia).

Birds and wildlife

The delta sits on the migration route between Europe and Africa along the western Mediterranean, so birds stop here to rest, moult, feed, nest and spend the winter. Catalunya.com names large populations of black-winged stilts, Kentish plovers, little ringed plovers and little grebes, wintering ducks, and three species in serious danger: the Eurasian bittern, the Balearic shearwater and the osprey. There is a native population of Spanish pond turtles and of the Spanish toothcarp, a small endemic fish. Kentish plovers nest on the beaches, and parts of the sand are closed in the nesting season.

For birdwatchers, Catalunya.com singles out moustached warbler and crakes in late March, western swamphen and bittern from the hides, collared pratincole from the Sabogal hide at Cal Tet, and shearwaters, razorbills and skuas off the beaches.

Accessibility and safety

Best time to visit

Catalunya.com says any season works but recommends spring and winter: March and April for migrants and the first summer visitors, winter for ducks, bittern and shearwaters off the beach. Summer brings wading birds to the marshes; note the shorter weekday hours then.
