Siena Cathedral is easy to visit, but a few small details can help you make your experience even better.
Opening hours change by season. And tickets can also be confusing because some include only the Cathedral and the Piccolomini Library, while others include extra places like the Crypt, Museum, Baptistery, and viewpoints.
This guide makes it simple. You’ll learn how to save time, when to arrive, the dress code, common mistakes to avoid (such as assuming the Gate of Heaven is included), and more.
Timing your visit
From late March to early November, Siena Cathedral opens 10 am to 7 pm (Mon–Sat). On Sundays and holidays, visitor entry starts at 1:30pm to 6 pm.
In the winter months, from early November to late March, hours are shorter at 10:30 am to 5:30pm.
On the day, arrive 10-15 minutes early, even if you already have tickets. And don’t plan around the closing hour; last admission is 30 minutes before closing.
Before you lock your plan, check the seasonal hours and Sunday timings here: Opening hours.
Marble floor is NOT always available for tourists
If the marble floor is one of your main reasons for visiting, remember it isn’t fully uncovered year-round. Here is the viewing window for the marble mosaic masterpiece:
- 27 June – 31 July
- 18 August – 15 October
Accessibility options: While the cathedral has a dedicated ramp for wheelchair access, it’s advisable to inquire about the accessibility of other areas like the Museum, crypt, and baptistery, as they may not have the same level of accessibility.
Choose the right ticket
Some tickets cover only the Cathedral (and the Piccolomini Library), while others cover the wider complex, including the Museum, Crypt, Baptistery, and viewpoints. See Tickets here.
Start with one question: Do you want to explore on your own, or would you prefer someone to lead it? If you’re visiting independently, choose between a Cathedral-focused ticket (for the main interior) or the OPA SI PASS (for the Museum, Crypt, Baptistery, and the viewpoint).
If you’d rather not plan the highlights yourself, a guided tour is the simplest option. Your entry is included, and you get the context as you walk. A private guided tour is best if you want to set the pace, ask more questions, or focus on specific interests.
Gate of Heaven is different; it runs on a timed rooftop route, so treat it as its own plan unless your ticket clearly says it’s included. Read more about the Gate of Heaven Tour here.
Don’t miss the audio guide (included with your ticket)
The official audio guide is included with the Basic Cathedral ticket and the OPA SI PASS, and you can use it on your smartphone. It’s a simple way to understand what you’re looking at without booking a guided tour.
Bring earphones/headphones, so you can listen without holding your phone up or disturbing others. Download the app before you enter, so you’re not relying on the signal inside.
If you only have 60-90 minutes
Go straight into the Cathedral, then step into the Piccolomini Library while you’re already inside. If you still have time, pick one more “must-see” and wrap up. This page helps you quickly choose what to see.
If you have 2-3 hours
Use the Cathedral as your starting point, then work outward: Cathedral + Library, Crypt, Museo dell’Opera +viewpoint, Baptistery. If you tend to move slowly in museums, give the Museo dell’Opera extra time, as it is usually where visits tend to stretch out. Helpful guides: Siena Cathedral Crypt and Opera Duomo Museum.
Ticket tip: In most cases, you can show your Siena Cathedral ticket as a QR code on your phone, and booking online ahead of time helps you avoid long ticket-office lines on busy days.
To be safe, save the ticket PDF or a screenshot offline, and carry ID if your ticket requires it. Keep a printed copy as a backup if you’re worried about low battery, poor signal, or scanning issues.
How to save time on busy days
The biggest time-saver is booking ahead, because you avoid the ticket-purchase queue and arrive ready to enter. The second time-saver is timing: early in the day or later afternoon often feels smoother than the midday peak. The third is knowing where you’re meant to go. Cathedral entry and some complex sites have different entrances, so your ticket instructions matter.

Common mistakes to avoid
The most common mistake is buying a complex ticket and then only seeing the Cathedral interior. Another is assuming Gate of Heaven is included, even though it’s often sold as a timed add-on.
Also, don’t plan to arrive right before closing, last admission is 30 minutes before the posted closing time, so the closing hour isn’t your real deadline.
Getting there (one tip that helps)
If you’re arriving by train, the easiest “Siena trick” is the escalator route from Siena Railway Station to Porta Camollia (via the Porta Siena shopping centre). It saves the steepest uphill part, then you can walk the last stretch to the Duomo. If you don’t want to walk uphill with luggage, take a bus (0S7 or 0S1) or a taxi to the center and finish on foot.
Flying in? The nearest airport is Florence (Amerigo Vespucci Airport), about 80 km away; Pisa and Rome are other common options, depending on connections.

Dress Code, bags, and photos (quick tips)
Dress code and bag rules are the easiest way to lose time at the entrance if you’re not prepared.
Keep your outfit simple; cover shoulders and knees. Strap tops and very short shorts/skirts can cause issues. The easiest backup is a light scarf, so you can cover up fast if needed. Bring a small day bag (it’s quicker at checks), and wear comfortable shoes. Siena’s streets are uneven, and any stairs/viewpoints are easier in stable footwear. For photos, follow signs and staff in each area, and assume anything “pro” (like tripods, lights, or drones) needs permission.

Frequently Asked Questions
Here are the questions visitors ask most often when seeking tips for visiting Siena Cathedral.
Which ticket is best if I’m short on time?
Choose a Cathedral-focused ticket. It gives you the main interior (and the Library) without committing you to multiple extra sites.
When is the OPA SI Pass actually worth it?
It’s worth it when you plan to visit multiple add-on sites, like the Museum, Crypt, Baptistery, and the viewpoint, rather than just the Cathedral.
Can I do the Cathedral and the main complex sites in one visit?
Yes, if you have about 2–3 hours. If you’re under 90 minutes, stick to the Cathedral and Library, plus one extra highlight.
Is morning or afternoon better?
Morning is usually smoother for entry flow. Late afternoon can also work well once the crowd starts to thin out.
Do the complex sites have separate entrances?
Yes. The Cathedral has its own entrance, and sites like the Museum, Crypt, and Baptistery are accessed separately, so don’t assume everything is entered through the Cathedral door.
Do I need to pre-book, or can I buy tickets on-site?
You can sometimes buy on-site, but booking ahead is the safer option on busy days because it avoids ticket-office queues and ticket sell-outs.
