You can walk comfortably and observe beautiful untouched nature at Paiva Walkways, located on the left bank of the Paiva River, in Arouca Geopark. Even though it seems easy, few hikers manage to cover an entire 8 km route in one day. The hills are quite steep and require much effort especially when it's hot, during the summer months. That's why the best time for the hike is spring and autumn. The route lies from the river beaches of Areinho and Espiunca to the Vau beach. Arouca Geopark has not only prominent flora and fauna but also important geological heritage, it's listed in UNESCO Global Geoparks Network.
