Very early. Before breakfast in fact. All self-respecting tourists are still sleeping out their hangovers. The sacrifices one must make for Art... More seriously though, if you want to get photos of the statues lining the south side of the bridge, early morning in June/July is perhaps the best time to do it. The sun is at the back of the statues the rest of the day, but in morning the light shines on the front of them.
