Fodor's Expert Review Paiva Walkways
This zigzag wooden walkway along the Paiva River offering scenic views of the river and the Arouca Geopark is widely celebrated. From start to finish, the 8-km-long (5-mile-long) trail hike takes about 2½ hours and allows visitors to experience the surrounding landscape—waterfalls, granite cliffs, endangered species, five geosites—without disrupting it. There’s river beach access from the walkway, in case you want to take a dip, and there’s a suspension bridge that provides amazing views. You can access the walkway from either Espiunca or Areinho. While there are cafés located at both ends of the trail, make sure you pack enough water and snacks and wear comfortable walking shoes as this is a strenuous hike, requiring you to climb a lot of stairs.
