Florence’s Uffizi Gallery welcomes over 8,000 visitors a day—and those numbers swell between April and October. General admission queues can take anywhere from 60 to 90 minutes between 10am and 1pm. Even in the quieter months, you’ll likely face a 30–45-minute wait if you haven’t booked ahead.
If you're booking on the spot (via door 2), prepare to meet long lines forming well before the 8:15am opening, often wrapping around the courtyard and bottlenecking at the entrance archway.
