Sao Martinho do Porto Guide

Sao Martinho do Porto is a bayside beach town in the Leiria region of Portugal, tucked into the municipality of Alcobaca on the Atlantic coast. Calm waters and cobbled sidewalks give the place an easy, unhurried feel from the moment you arrive. It sits about 14 km south of Nazare and roughly 100 km north of Lisbon, close enough for a day trip yet far enough to feel like its own world. The whole town wraps around a narrow inlet that opens only about 200 m to the ocean, feeding a lagoon that stretches 1400 m long and 900 m wide.

The bay itself is the reason people fall for Sao Martinho do Porto. Shaped like a scallop shell, it holds calm water and fine white sand that make it one of the most beautiful beaches in Portugal. Praia de Sao Martinho, the main stretch of sand, has clear water that is ideal for swimming. A natural reef out front keeps the sea gentle enough for families with small children. You can wade in without worrying about currents, which is rare on this stretch of coast.

Walk the cobbled sidewalk that runs along the beach and you will pass a string of small cafes with tables angled toward the water. Concha Residencial, for one, sits just 50 m from the shore. Hotel Santo Antonio Da Baia is about 600 m from the beach, and Sao Martinho do Porto is easy enough to cross on foot between the two in a matter of minutes. Climb the hill above town and you reach the Chapel of Santo Antonio, which looks out over the whole bay.

On the southern side of town, a protected dune landscape shelters local wildlife. The lagoon itself curves in a broad circle around the town, visible from almost every angle. Because the bay is so sheltered, it draws sailors and windsurfers who use the calm water for competitions rather than just cruising. Boat trips run out onto the lagoon so you can see the coastline from the water. Rental shops along the beach set you up with kayaks and paddleboards for an hour or an afternoon. Sao Martinho do Porto is also known for surfing and water sports, with access to the Berlengas archipelago further up the coast.

A short drive brings you to Nazare, famous the world over for its record-breaking waves. A 16th-century fort there once guarded the harbor and now offers panoramic views over the Atlantic and the village below. Salgado beach is only a few minutes' drive from Sao Martinho do Porto as well, if you want another stretch of sand without the crowds.

Between the sheltered bay, the cobbled streets and the easy day trips on either side, Sao Martinho do Porto feels like a place built for slow mornings and long lunches. It rewards visitors who are happy to walk rather than rush, letting one calm afternoon lead into the next.
