This walk is a real change of scenery, with a touch of the Chinese Wall about it. You'll find yourself in the middle of nature and will be able to observe 9 biospots along the 8,700-metre route, discovering insects, animals and plants along the way. You can also see a waterfall (Aguieiras) and a waterfall that flows into the Paiva river (the Gola do Salto). During your walk, you can even take a break to swim in the river on Vau beach.
As for the 516 Arouca suspension bridge, crossing it will provide you with a thrilling experience in complete safety, 175 metres above the Paiva river, one of the wildest in Portugal. Be warned, though, that the bridge moves when you step on it, so you'll have to summon up all your courage and forget that you're afraid of heights.
