The Arnóia River rises in the Serra de Todo o Mundo and flows for 30 km before flowing into the Óbidos Lagoon. A dam was built about one and a half kilometres from Óbidos, in the Horta Valley, whose reservoir was used to irrigate the area's crops.

Artificial lake, with a very pleasant surrounding area. In summer, especially at weekends, the area is very popular with families and groups for picnics. Note: The description below seems to refer to another place, which I think is the Ermida Bridge

Small artificial lake, where we can sometimes see some wild birds. There is a shooting range nearby, if you hear gunshots, be careful.

Surrounded by beautiful and abundant trees, it is a bridge with a Romanesque arch. There are several theories regarding its construction; some argue that it was built during the reign of D. João II, in order to facilitate the King's movement when he went to meet Queen D. Leonor for a swim in Caldas, while others claim that it was built in the 19th century due to a technical issue, namely its width. Interestingly, this bridge supports two enormous pine trees at the top of the road.

This area, which is home to vast meadows, owes its name to the fact that in the past (80 or 90 years ago) it was a place where wild cattle were allowed to graze freely. Next to a small lake created to retain rainwater (surface water is rare in the Serra de Montejunto, as it is a mountain made up mostly of limestone), you can still see the ruins of an old stable where the animals spent the night to protect themselves from the cold. Today, this area, especially in the autumn and winter months, is used as a grazing area for goats and sheep. In the spring and summer, these fertile meadows are used by the populations of the nearby villages (Cercal and Rocha Forte) to grow crops such as potatoes and other dryland crops.

Built in 1997, the Sobrena (Cadaval) dam never filled. It was expected to irrigate 100 hectares of agricultural land, benefiting 120 farmers, mainly Rocha pear producers. The dam is an exposed ruin, with the support buildings invaded by brambles and a wall from which a pond can be seen in the place where a reservoir should have been. All around you can see eucalyptus trees. And these trees are precisely one of the reasons for the failure of this investment of more than two million euros.
