Early mornings, right after opening, offer the least crowded experience. Consider planning your visit in early April or late September for optimal conditions.

If you're late, you might miss the tour, as they tend to start promptly. Latecomers may not be able to join the group or receive a refund. Aim to get to the meeting point at least 15 minutes before the scheduled time so that even if you lose your way or face any delays, you’ll still have some buffer time. This way, you can make the most of your Duomo Florence experience.
