São Martinho do Porto Beaches

Overview

São Martinho do Porto is a charming seaside town known for its unique, perfectly shell-shaped bay. This natural harbour creates exceptionally calm waters, making Praia de São Martinho do Porto one of Portugal's best and safest beaches for families with children. The gentle waves are ideal for swimming and playing right by the town's promenade, offering a relaxed holiday atmosphere.

While the main bay offers safe swimming, the Atlantic water here is typically refreshing rather than warm. At the southern end of the bay lies Praia de Salir do Porto, famous for its impressive sand dune, reportedly one of Portugal's highest, easily reached via a scenic boardwalk. For a wilder feel, the secluded cove of Praia da Gralha sits just north of the bay. This calm setting contrasts sharply with nearby Nazaré, home to the legendary giant waves of Praia do Norte, a must-see spectacle for surf enthusiasts, especially in autumn and winter.

Beyond the main bay, Praia da Foz do Arelho offers a different experience, where you can choose between the calm Óbidos Lagoon or the open Atlantic. The atmosphere in São Martinho is that of a relaxed, traditional Portuguese resort, appealing to families and couples seeking an authentic coastal escape. For those seeking even longer stretches of sand between São Martinho and Nazaré, Salgado Beach provides a more natural setting. Discover more coastal gems in our full guide to the area's beaches.

How do the tides change the beach experience?

Tides significantly affect the beach area, particularly near Salir do Porto at the southern end of the bay. At low tide, a much larger expanse of sand is revealed, sometimes creating shallow pools perfect for children. You can also cross the Tornada River on foot more easily at low tide to access the Salir dune. At high tide, the water comes much further up the beach, reaching the base of the Salir dune. High tides combined with storms can occasionally cause water to reach the promenade.

What is Praia da Gralha like compared to the main beach?

Praia da Gralha, located just north of the São Martinho do Porto bay, offers a different experience. It's a more natural and wild beach, facing the open Atlantic, though situated in a wide bay. It has a long sandy stretch backed by high cliffs. It's less crowded and lacks the amenities of the main town beach but is popular for paragliding from the cliffs above. Access is via a road from the north of town, which can be steep, and parking might be limited or informal.

Praia da Gralha

Is São Martinho do Porto sheltered from the wind?

Yes, the bay of São Martinho do Porto offers significant shelter from the prevailing Atlantic winds, especially compared to nearby coastal towns like Nazaré or Peniche. The high headlands surrounding the bay's entrance block much of the wind, contributing to the calm water conditions and making it more pleasant for sunbathing and relaxing on the beach, particularly during the shoulder seasons when coastal winds can be stronger.
