São Martinho do Porto

São Martinho do Porto is a Portuguese coastal town and resort destination situated on the Silver Coast, within the Alcobaça municipality. The location is renowned for its unique, perfectly shell-shaped bay which is almost entirely enclosed by steep hills. This exceptional geographical feature results in sheltered, calm waters, making the bay a favored point for family recreation and safe nautical activities. The connection to the Atlantic Ocean is maintained through a narrow channel carved between the surrounding cliffs. The town retains a small, active fishing port and serves as a popular tourist center defined by its extensive wooden boardwalk and the striking geometry of its natural harbor.
