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.

At this exact spot there is only a turning circle for cars - and Google Maps also shows the spot a few 100m further to the southwest: so there is nothing right here!

The Pena da Gouvinha fountain used to serve the locals. There was a queue to fill the bottles, so much so that it was decided that each resident could only take eight bottles of water and would have to “give others a chance”. Today it serves as a stopping point to cool off during the walk and, if you wish, you can take advantage of the place to eat whatever you have prepared at home. There is a picnic area next to the fountain. The place name Pena da Gouvinha suggests that barbarians passed through here. Gouvinha is a personal name of Germanic origin, still documented in the 12th century as Gaudina.

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.
