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

An entrance in the city wall, with some tile panels that I loved seeing.

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.

The Óbidos Lagoon is the largest coastal lagoon system on the Portuguese coast. It has a total area of approximately 6.9 km2 and an average depth of two metres, with elevations ranging from half a metre to five metres. It extends upstream essentially through two channels, to the west by the Braço do Bom Sucesso, and to the east by the Braço da Barrosa. It shares a land border with the municipality of Caldas da Rainha to the north (parishes of Foz do Arelho and Nadadouro) and with the municipality of Óbidos to the south (parishes of Vau and Santa Maria). 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.

It is best to visit in the winter months, when you have air in the narrow streets
