If you visit this reservoir, be sure to visit the other dam, Odeleite, a few kilometers further north, which is almost even more beautiful. At both dams you will find hiking trails, peace and quiet, and sleepy villages.

The reservoir is really beautiful. But I haven't seen a full lake here for years. The drought here is getting worse every year

In the middle of the plantations, along the route, you will find this picturesque place with a ruin of an old mill. The building is in complete abandonment, but it still serves as a good stopping point.

Ribeira do Beliche is one of the main watercourses in the region. Further ahead, it feeds the reservoir of the same name. At this point on the route, you cross the river. A beautiful place and ideal for a stopover.

Moinho das Pernadas is located on the right bank of the Odeleite river. It is an old hydraulic mill undergoing rehabilitation by the City Council. The mill was reactivated, after spending many years (since 1980) in oblivion. It is accessed from the bank opposite this point. However, it is possible to admire it from an even more favorable angle from here.
