In the summer they have light shows bouncing off the stones of the bridge and open air concerts on the banks of the river. You can visit it then but when we went last month it was a bit cold and drizzly and we were one of three groups of people there. It was quiet as we walked across and we were able to get close and really look at it, to explain to the kids how and why it was built, and take photos without the summer's tourists getting in the way.

You can enter at either side of the river where you will find large parking lots and a collection of buildings housing a little cafe, gift shop, museum and public toilets. Parking is 15 euro per car in high season, 10 euro per car in low season but admission after that is free. Visit the link above for all the information regarding directions, entry and high season activities.
