São Martinho do Porto is a resort unique in Europe, famous for its shell-shaped bay, one of the few naturally enclosed bays on the Atlantic. Its calm, shallow waters, ideal for families, contrast with the open Atlantic coast, offering an exceptionally gentle seaside experience year-round.
Part of the municipality of Alcobaça, in the Oeste region, São Martinho do Porto sits just 15 km from Nazaré, 25 km from Óbidos, and 100 km from Lisbon. The resort thus offers the ideal combination of an exceptional sheltered beach, quick access to the Silver Coast, and proximity to Lisbon.
Long a hidden gem, the resort has gradually been discovered by the French, Dutch, and British, drawn by its preserved authenticity, still-reasonable prices, and off-season tranquility. The village retains a charming historic center with its colorful fishermen’s houses, fresh fish restaurants, and local shops.

The São Martinho do Porto real estate market is mainly structured around demand for seaside second homes and seasonal rental investments. Supply is limited, which supports prices over the long term.
1- to 3-bedroom (T1 to T3) apartments on the bay front or a few minutes’ walk from the beach are the most sought-after and most liquid product on the market. Views over the shell-shaped bay, terraces, parking. Very high demand both for purchase and rental. Gross seasonal rental yield: 6% to 9%.
3- to 5-bedroom (T3 to T5) houses on residential streets near the bay are an excellent choice for a family second home or primary residence. Supply here is more plentiful than for apartments, with generous floor areas and often landscaped gardens.
The premium segment of São Martinho do Porto comprises contemporary or renovated villas with pool and garden, often located on the heights overlooking the bay. These properties are the seasonal rental investment par excellence in the resort, with sustained international demand from April to October.
A few renovation opportunities still exist in the historic center and the old village alleys. These properties offer a lower-priced entry into a mature market, with strong value-add potential at resale or for rental once renovated. Floor areas are often compact (50 to 120 m²).
São Martinho do Porto is the ideal destination for a family second home. Its sheltered bay, calm child-friendly waters, off-season tranquility, and preserved authenticity make it an exceptional seaside place to live, 1 hour from Lisbon. The €2,890/m² price remains very competitive against comparable destinations on the French or Spanish coasts.

The São Martinho do Porto rental market is heavily shaped by seasonal demand. The rental median of €11.5/m²/month on long-term rentals generates decent yields, but it is seasonal rental that delivers the best performance.
In short, São Martinho do Porto is one of the best markets on Portugal’s Silver Coast for seasonal rental investment, combining a unique bay, strong international tourist demand, and a rental supply structurally insufficient to absorb summer-season demand.
