The Vouga is the second largest river entirely in Portuguese territory. It is a river of limpid waters, with riverside forests and oak groves populating its banks (V1 – Ponte do Poço de Santiago, V2 – Praia fluvial da Quinta do Barco, and V13 – Lenteiro do Rio). For more than 150,000 years the human being made his presence around here, as evidenced by the recent discoveries made at the mouth of the Teixeira river (V9 – Albufeira de Ribeiradio). The megalithism here has great expression, as seen by the presence of countless dolmens in the Talhadas mountain range, especially the Anta da Capela dos Mouros (V7), more than 6000 years old and found artifacts indicating that those peoples already practiced agriculture. In the vicinity of the Vouga river, the waterway of Carrazedo (V4) and Paradela (V10) invite to a stroll by the edge of the murmuring waters on hot summer days.
