Poorly maintained, some sections dangerous because of landslides due to the water and rain. If you like to bike in dense vegetation and get your face smacked, this is for you. If else, take the road nearby

The Porta da Vila is the city's main gate. It consists of two low, staggered gates to prevent a direct cavalry charge, as was often the case with Gothic Portuguese castles. Between the gates is a small balcony that served as a prayer room, with beautiful blue and white tiles (azulejos) from 1740 depicting the Passion of Christ. Street performers often play there because of the acoustics.

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.

To the south is the Poça do Vau and to the west it is connected to the Poça das Ferrarias. It has a maximum length of 6 km and a width that varies between 1 and 1.5 km, with a preferential NW-SW orientation.
