Praia da Areia Branca, Coastal beach in Lourinhã, Portugal

Praia da Areia Branca is a beach and village in the parish of Lourinhã e Atalaia, on the Atlantic coast of Portugal's Oeste region, 72 km north of Lisbon and 15 km south of Peniche. The wide white-sand beach faces the Berlengas islands, and the bars that made it known stand on the seafront wall directly above the sand. The Rio Grande flows into the sea beside the campsite.

Praia da Areia Branca grew as a settlement and beach in the parish of Lourinhã e Atalaia, municipality of Lourinhã. The nearby Rio Grande, which flows into the sea at the beach, was once used by bathers to cool off. In 2009 and 2010 the beach received the Blue Flag.

The bars that made the beach famous stand on the seafront wall directly above the sand, though there are few terrace cafés. Surf schools run by some of Portugal's first-generation surfers also offer accommodation, and hostels and surf houses cater to longer stays.

The beach is reached via the EN 247 national road, 15 km south of Peniche and 65 km north of Lisbon. Access is adapted for visitors with disabilities, and sunshades and awnings can be rented on site. Showers are available, and the Rio Grande flows into the sea here seasonally.

The Rio Grande only reaches the beach seasonally, so the stream beside the campsite appears in some months and not others. Bathers once cooled off in its freshwater near the spots busy in summer. The Berlengas islands can be seen from the sand.
