Els Alfacs Bay (Badia dels Alfacs), La Ràpita

Els Alfacs Bay (Badia dels Alfacs) is the large, shallow bay at the southern end of the Ebro Delta, closed off from the open sea by the Trabucador sandbar and the Punta de la Banya. La Ràpita sits on its western shore: the fishing port and fish auction are about 1 km on foot from Plaça de Carles III, and from the town you can take a boat trip, eat mussels and oysters farmed in the bay, try windsurfing or kitesurfing on flat water, or watch the seabirds that feed there. It suits food lovers, birdwatchers and water-sports beginners; skip it if you want dramatic scenery or deep water.

Quick facts

• Names: Badia dels Alfacs or Port dels Alfacs (Catalan), Bahía de los Alfaques or Puerto de los Alfaques (Spanish).
• Where: southern Ebro Delta, between La Ràpita, the delta plain and the Trabucador sandbar. It is one of the Ebro Delta Natural Park’s two bays.
• Coordinates: 40.6256, 0.6359 (middle of the bay).
• Size: about 5,894 ha of water, 4 m deep on average and 6 m at most, holding roughly 200 million m³ (Ebro Delta Natural Park).
• Seabed: a shallow shelf 0–1.5 m deep runs round the edge, then drops to the central basin. Seagrass meadows of Zostera noltii, Cymodocea nodosa and Ruppia cirrhosa cover much of the floor.
• From Plaça de Carles III: the fish auction building (la Llotja) is about 1.1 km on foot; the Garbí beach about 0.7 km.

How the bay works

The natural park explains that the Punta de la Banya and the Trabucador formed when the sea eroded and redistributed the sediments of the delta’s old southern lobe, and that they already appear clearly on 16th-century maps. Fresh water enters mainly as drainage from the rice fields, and in calm weather a layer of brackish water floats over the saltier sea water below. Strong easterly storms can push the sea over the sandbars.

The result is calm, shallow water, rich in nutrients: good for shellfish, fish, birds and learners on a board.

The port and the fish auction

catalunya.com calls La Ràpita one of the most important fishing ports on the Catalan coast, both for the volume of its catch and for the business it generates, and recommends attending the traditional auction at the fish market. On OpenStreetMap the auction building, la Llotja, stands on the south side of the port, about 1.1 km on foot from Plaça de Carles III (roughly 15 minutes), and a visitor area is mapped on its first floor. Our La Ràpita town guide explains the viewing gallery; landing times change with the season.

The port’s history goes back further than the modern town. The natural park’s history page says that when the Moriscos were expelled at the start of the early modern period, about 40,000 people from Aragon left through the port of Els Alfacs. In the 18th century the Bourbon kings planned a canal, fortifications for the port and the new town around Plaça de Carles III (spain.info); the old navigation canal still reaches the port at a lock, the Resclosa del Canal de Navegació, about 0.7 km on foot from the square.

Mussels, oysters and the food calendar

The park lists the mussel farms (musclera) among its ten highlights and says the calm, nutrient-rich water of the bays allowed marine farming, mainly of mussels, on platforms in the water; it adds that Ebro Delta mussels stand out for their flavour. OpenStreetMap maps a mussel-farming area of about 1.2 km² along the northern shore of the bay, roughly 2–7 km east of the town centre.

catalunya.com recommends touring the bay by boat and tasting mussels or oysters on a floating farm. It also lists the town’s food days: mantis shrimp days (17 February), a mussel and oyster day (2 June), the Flavour Days from 2 June to 2 July, and a king prawn day (8 December). Check the current year’s dates.

Birdlife

The park says the calm bay water and its seagrass feed seabirds, and that the delta has records of more than 360 bird species and some of the most important seabird breeding colonies in the Mediterranean. Autumn is the big season: in October and November, after the rice harvest, thousands of waterbirds arrive on migration or to winter. For a closer look, OpenStreetMap shows the bird hides and the Casa de Fusta ornithological museum on the Encanyissada lagoon, about 8 km north-east of the town centre, and catalunya.com mentions a bike route there from La Ràpita. The Punta de la Banya across the bay is a restricted nature reserve; see our Trabucador and Punta de la Banya guide.

Water sports and boat trips

The La Ràpita nautical station organises canoeing, water skiing, kitesurfing, windsurfing and guided boat routes, mainly in Els Alfacs Bay, which the Trabucador shelters from the open sea (catalunya.com). catalunya.com also lists surfing and windsurfing among the bay’s uses. We could not confirm boat-trip prices, schedules or operators; ask the nautical station.

Access and parking

On foot: from Plaça de Carles III, the Garbí beach is about 0.7 km and the fish auction about 1.1 km, measured along streets on OpenStreetMap. The town beaches, all on the bay, are covered in our La Ràpita beaches guide.

Around the bay: OpenStreetMap shows the L1608 bus between Amposta, La Ràpita and Poblenou del Delta, on the north side of the bay; we could not check its timetable.

Accessibility and safety

Best time to visit

For birds, come in October and November, when the park says the flooded rice fields fill with migrating and wintering waterbirds, and go out in the morning or at dusk. For shellfish, time a visit for the mussel and oyster day in early June or the Flavour Days in June. For water sports, choose spring to autumn and a windy day.
