This part of the tour in particular is highly recommended. If you don't want to walk the whole way, you can return halfway to Alvarenga via another suspension bridge or take a taxi.

April 5, 2026, Arouca 516 Suspension Bridge (Ponte Suspensa de Arouca) – Alvarenga Entrance

Starting point A is not safely located. It leads through impassable terrain or over non-existent paths. We aborted our descent from the bridge (Highlight 1) to starting point A and, thanks to the friendly guides at the bridge, were able to use it for the safe return to our car. Anyone who wants to do the whole loop should book a ticket for crossing the bridge in advance. Attention: limited ticket contingent per day.

This small suspended walkway appears discreetly along the wooden path that leads to the imposing 516 Arouca bridge. Here, you cross the Paiva River in a more intimate and serene way, feeling the water flowing below while the sounds of nature surround you. A kind of charming appetizer before the great spectacle of the main crossing.

If you cross the bridge at Alvarenga and then take the wooden walkway along the Rio Paiva to Espiunca, you should remember that you will need a taxi from there back to the starting point. A later return via the Arouca bridge is not possible. However, if you just want to walk across the bridge and back, this is no problem with your ticket booking (online). The Alvarenga side is recommended for people who want to avoid the many wooden steps and just want the pure bridge experience.

Beautiful "wooden path" with impressive views. There are lots of stairs to climb up and down, especially the way back has to be taken into account, or halfway there at 2.5km (from the entrance) you can order a taxi from the nice guy. The suspension bridge is impressive... all in all a great experience with swimming opportunities to cool off... we were there at 39*. Part of the path is shaded.

When it rains, the wood is a little slippery despite the grooves, so just be a little more careful, but there is a railing so you can hold on. You have to climb around 500 steps to get to the top and not far from the next attraction, the bridge itself.

The wooden staircase construction must first be conquered, there are around 500 steps to the top. But in return you get a great view of the narrow valley, which has been carved by the Paiva River over millions of years. Because the stone is very hard, the gorge is V-shaped.
