About the Beach
Praia de São Martinho do Porto is unique in mainland Portugal — a near-enclosed shell-shaped bay that creates extremely calm, warm and shallow water, ideal for children and less confident bathers. The natural geometry of the bay, with its narrow opening to the ocean, gives it an almost lagoon-like character. It is one of the most family-friendly and safest bathing destinations on the entire Portuguese coast.
