PR4 MAC - Rota da Ortiga

The Tagus, riverside wildlife and Ortiga’s traditional fishing structures

The Ortiga Route stands out for its varied landscapes and its connection with the local communities and waterways that shape this area. Around the parish of Ortiga, agricultural land and pastures coexist with riverside environments in a transition area between Beira Baixa, Ribatejo and Alentejo.

The River Tagus is one of the main features of the route, alongside the Boas Eiras and Eiras streams. The riverbanks support riparian habitats with ash trees, alders, black poplars and willows, while the slopes are home to species such as cork oaks and holm oaks. This variety of habitats also supports numerous bird species, including the common kingfisher, European bee-eater and osprey.

The natural heritage sits alongside traces of different periods of human occupation. Among the main points of interest are the ruins of the Vale de Junco Bathhouse, associated with the Roman presence, and the Ortiga fish weirs, traditional structures built beside the Tagus to facilitate fishing. These structures bear witness to the river’s historical importance to the communities that depended on its waters.

The landscape also reveals traces of the region’s geological history, including folds, ancient river terraces and very old rock outcrops. The Ortiga Route therefore offers a broad perspective on the relationship between the river, nature and human activities.
