Can I walk the bridge at any time of day?

When purchasing tickets for access to 516 Arouca, you will have to choose a time to make your visit. You must appear at the meeting point, defined for this purpose, 15 minutes before the selected time. The visit will start at the scheduled time. If you are late, and if there is availability, you can join a next visiting time on the day the visit is scheduled. In case that it is not possible to join a group on the same day, you will have to purchase a new ticket for another day and time.
