Some people choose to visit the 516 Arouca Bridge as a standalone activity from Alverenga. This is ideal if you only wish to visit the bridge, and not experience the rest of the boardwalk, as you avoid the steep incline and decline of the staircase from Areinho. If you wish to combine with a walk on the boardwalk, starting at Alverenga is not ideal because you would have to book a separate bridge ticket at a specific to return to Alverenga after walking the boardwalk.
