July 5, 2025, Penedo Furado Rock Arch

Penedo Furado dates back to the Jurassic period, when the sea bathed this inland area, close to Nadadouro. It is now a huge rock, light brown in colour and on the side facing the Óbidos Lagoon, signs of erosion are visible, with deep cavities and one of them ended up going through the rock, forming a passage.

Salir do Porto has a river beach, on the bank of the Tornada River, which flows into the bay of São Martinho do Porto. Salir beach is famous for its sand dune about 50 meters high. Once the largest in Europe, the Salir Dune stands out in the dune landscape of São Martinho Bay. The core of the Dune is partly made up of red sandstone, a vestige of an older dune – a fossil dune. There are other rock beaches in the coastal area that are locally called Quebradas. It was in the Ruins of the artisanal Customs House of Salir that the caravels that participated in the discoveries and conquests were built during the reigns of D. Afonso V and D. João II. The extinct parish was made up of the towns of Salir do Porto, Casais de Salir do Porto and Bouro.

Be sure to go up there from the top, great view and slide down on your bum. Large dune that clings to the rocks there, perfect for hiking. At the foot of the dune, the Tornada river flows into the sea.

Praia de Salir do Porto is next to the mouth of the Rio Tornada or Rio Salir on the south bank. The sand is very extensive, it is wider in the south and narrows as we walk north. This beach is known for its huge dune about 50 meters high, the highest in Portugal.

Beautiful long stretched beach with steep cliffs behind. Often deserted because there are no restaurants, toilets, etc. Of course, therefore also unguarded. Parking is possible either at the end of an unpaved road that is easy to drive on or on paved ground above the cliff.
