Even on a tight schedule, Ponte Vecchio earns the hours.
Allow 15–30 minutes.
Seen from a neighbouring bridge at golden hour it's genuinely magical, and the jewellers' shops jutting over the water are unlike anything else. The catch: walking across it is a slow shuffle through a tourist crush, the gold is wildly overpriced, and the bridge is better admired from afar than experienced on. It's a five-minute photo, not a destination.
