"Paiva Walkways are located on the left bank of the Paiva River, in Arouca municipality, Aveiro, Portugal. They are 8 km that provide a walk "untouched", surrounded by unique beauty of landscapes, in an authentic natural sanctuary along the brave waters downhills, quartz crystals and endangered species in Europe. The route extends from the river beaches of Areinho and Espiunca, lying between them, the Vau beach. A journey through biology, geology and archeology that will remain, of course, in heart, soul and in mind of any nature lover." (Passadiços do Paiva)
