Praia da Costa de Santo André

  • Distance20km north of Sines
  • Best seasonJune-September
  • TransportCar (recommended)

Praia da Costa de Santo André runs in a long, straight line of sand roughly 20km north of Sines, backed by pine forest and the freshwater Lagoa de Santo André just inland. The beach is wide and fully exposed to the open Atlantic, with fine sand and moderate surf, and its straightness means there are no coves or headlands to break the wind, so conditions can feel breezy even on calm days elsewhere along the coast.

A long, straight sandy beach backed by pine forest and the Lagoa de Santo André, popular with birdwatchers and campers rather than resort tourists.

Praia da Costa de Santo André runs in a long, straight line of sand roughly 20km north of Sines, backed by pine forest and the freshwater Lagoa de Santo André just inland. The beach is wide and fully exposed to the open Atlantic, with fine sand and moderate surf, and its straightness means there are no coves or headlands to break the wind, so conditions can feel breezy even on calm days elsewhere along the coast. Water clarity is generally good, though the surf and occasional rip currents mean swimmers should stay alert, particularly given the more limited facilities compared with resort beaches further north. The area is better known for camping, birdwatching, and quiet walking than for a beach-club scene: a well-established campsite sits just behind the dunes, and the adjacent lagoon is a notable stop for migratory birds, drawing binoculars-equipped visitors as much as sunbathers. A seasonal beach bar operates in the main summer months, but there is no permanent restaurant or shop directly on the beach, and visitors typically bring supplies from Santiago do Cacém or the campsite's small store. Parking is informal and limited, set among the pines behind the dunes, and while it can fill on August weekends, the beach's considerable length usually leaves room to spread out. There is no direct public transport to the beach, so a car is necessary for most visitors, with the nearest town, Santiago do Cacém, about a twenty-minute drive away. The combination of pine forest, lagoon, and open dune beach gives Praia da Costa de Santo André a wilder, more outdoorsy character than the beaches around Comporta, appealing to campers, birdwatchers, and those seeking long beach walks over resort amenities.
