For beauty & photography, Sunrise Walls Photography Walk delivers.
If you do only one version of the walls, the opening-bell walk is the connoisseur's choice — near-solitude, gentle morning light on the roofs, and a temperature you can actually enjoy. The honest catch is the early alarm and that it's still the full €40 summer walls ticket; some softer-lit corners are still in shadow at 8am. The crowd and heat payoff is enormous.
