I’ve stood in line to get into dozens of European sites over the years, and I’ve also walked past those lines with a prepaid ticket in hand. No prizes for guessing which option resulted in a better (and faster) experience.

Some of Europe’s greatest art and architecture now runs on timed tickets, and the best sights sell out weeks or even months ahead.

If you show up without a reservation, you’ll see the outside of the building and lots of disappointed people milling about.

You don’t want to be those people.

Here are the 15 sights I’d book first, sorted by how early you need to move. Each one links to the post where I tell the full story, mistakes included, because I’ve been traveling in Europe for a long time and I’ve made a few.

Tier 1: Book the Day Tickets Open

Timed tickets to these sites sell out within a few days, and in some cases (Anne Frank House) within a few hours. Put the release date in your calendar and set an alarm.

1. Leonardo’s Last Supper, Milan

When to book: Tickets go on sale in quarterly batches, about three months ahead, at noon Milan time on an announced date. Online bookings are limited to five tickets.

Why it sells out: Small groups get a short, timed visit to protect the fresco, so there aren’t many tickets to go around.

In my Northern Italy itinerary, I suggest you book as soon as you know your dates in Milan.

BUT, if you didn’t buy tickets in advance, don’t despair.

On a recent trip to Milan, I booked a guided tour through GetYourGuide the day before my visit. Yes, it cost more than a regular ticket, but I learned a lot more than I would have on my own. The Last Supper itself is remarkable, but so is the history of the monastery.

One of the most poignant things the guide pointed out was that the wall on which The Last Supper was painted was still standing when everything around it had been reduced to rubble during World War II.

2. Anne Frank House, Amsterdam

When to book: Online only, from the official website. Every Tuesday at 10 am CET, tickets are released for dates six weeks later.

I went online six weeks before my visit and found only a handful of spots left. Living in the Pacific time zone, I was competing with hundreds of people who got out of bed earlier than I had.

I arrived at Anne Frank House clutching my hard-won reservation, only to discover that I’d booked the wrong date. The post tells you what happened next and what you’ll see at Anne Frank House (and yes, it’s worth setting an alert on your calendar).

3. The Alhambra, Granada

When to book: Up to three months ahead. Your ticket includes a set time slot for the Nasrid Palaces, the jewel of the complex, and that time is not flexible.

Take a taxi up the hill (they’re not expensive) and line up at the Nasrid Palaces entrance about thirty minutes before the time on your ticket. Afterward, wander over to the Generalife Gardens, which are usually less crowded and have many more fountains.

The Alhambra is one of those iconic sites that lives up to the hype. Even with the crowds, it’s worth visiting.

Tier 2: Book as Soon as the Window Opens

Booking windows run 30 to 60 days. In peak season, the best slots go in the first few days.

4. Sagrada Família, Barcelona

When to book: Official tickets open about 60 days ahead. In peak season (April to October, Easter and Christmas), book at least two to four weeks out. Tower tickets go fastest. With the new Tower of Jesus Christ inaugurated in June 2026, the basilica is busier than ever.

I confess I didn’t visit the Sagrada Família until my third trip to Barcelona because I hadn’t bought tickets in advance and I didn’t want to wait in line in 35+ degree heat.

When I finally did visit, it was because I got wise and bought my ticket online well in advance. Be warned: even with a ticket, arrive 30 minutes before your entry time.

5. Eiffel Tower Summit, Paris

When to book: Summit-by-elevator tickets go on sale 60 days ahead, and the tower itself recommends booking early. Summit tickets sell out fast in July, August and over Christmas. You can’t upgrade a second-floor ticket to the summit on site.

Full disclosure: I think you can admire the Eiffel Tower perfectly well from the ground. But if going up is on your list, buy your tickets well in advance. You’ll probably still queue, just not for as long, and you won’t risk being turned away when the tower hits capacity.

6. Vatican Museums and Sistine Chapel, Rome

When to book: Official tickets go on sale 60 days ahead. In summer and around Easter, the early morning slots sell out three to four weeks out.

My favorite Sistine Chapel memory is the woman behind me who asked her companion, “Do y’all think it was done by hand?” I resisted the urge to turn around and tell her it was paint by numbers.

Even with advance tickets, you’ll be touring the Vatican Museums with thousands of your new best friends. I’ve never visited when the place hasn’t been mobbed. I’ve heard that going later in the day is better than going early, but I haven’t tested that theory yet.

7. Galleria Borghese, Rome

When to book: Reservations are mandatory for everyone, even on free days. The official shop sells about six weeks ahead, visits last exactly two hours, and each shift admits about 180 people. From April to October, popular shifts (especially 11 am) sell out well before the window closes.

The gallery sits inside the Borghese Gardens, which are worth a visit in their own right to watch Romans enjoying nature. Plan your gallery slot and your garden time together.

If you arrive in Rome without a reservation for the Galleria Borghese, book a tour through GetYourGuide. That’s what I did on one trip, and my experience was much better with a guide than it had been when I toured the museum on my own a few years earlier.

People visit the Borghese for the exquisite Bernini statues (and they are amazing), but I was also very taken with the mosaics showing gladiators at work.

8. The Colosseum, Rome

When to book: Tickets are released 30 days before your visit, with a timed entry slot. They’re issued in your name, so bring ID. A standard ticket does not include the arena floor or the underground, and those sell out first.

Arriving without a timed-entry ticket is mistake number one on my list. Mistake number two is assuming a standard ticket gets you into the arena or the underground. Learn from my mistakes.

I also made the mistake of taking a guided tour, thinking it would get me into the Colosseum faster. It didn’t.

Tier 3: Book Two to Four Weeks Ahead

You have a little breathing room here, but not much in high season.

9. Scrovegni Chapel, Padua

When to book: Pre-booking is required. Visits last about 15 minutes, groups are capped at 25, and you can book up to the day before (no same-day reservations). Be at the waiting room five minutes before your time; latecomers won’t be admitted.

On any Padua itinerary, the Scrovegni Chapel deserves the top spot. Giotto’s exquisitely rendered figures will dance in your head long after your visit. Book as soon as you know your date.

10. Van Gogh Museum, Amsterdam

When to book: Timed tickets online, at least two weeks ahead, and earlier in the busy summer months.

Even with timed entry, it gets tiring dodging the crowds, especially if, like me, you take photos and read every caption. An early slot helps.

11. Uffizi Gallery, Florence

When to book: Reserve a timed entry in advance, especially from spring through fall. November to March is calmer.

I visited in the quieter season and the Uffizi was still thronged. Long lines of people queued for tickets, and it was almost impossible to get a decent shot of either of the two most famous Botticellis.

But it’s worth it. The Uffizi houses one of the world’s premier collections of masterpieces. It’s a must-see.

12. Neuschwanstein Castle, Bavaria

When to book: Online through the official ticket shop, which updates daily. A limited number of same-day tickets go on sale at the Ticket Center in Hohenschwangau from 8 am, and in busy periods they’re gone by late morning.

I stayed at a charming family hotel just over the border in Austria, and after dinner, with the valley still bathed in golden light, I walked the trail toward Mad Ludwig’s castle. You can hike there in about an hour or cycle in 30 minutes. Getting inside is the part that needs a reservation.

My travel plans didn’t allow time to see inside the castle, but if you do have the time, you’ll be amazed by what you see. They didn’t call him Mad Ludwig for nothing.

13. The Louvre, Paris

When to book: All visitors need a timed entry ticket, even those who get in free. Book two to six weeks ahead, especially in summer. As of January 2026, visitors from outside the EEA pay a higher price.

The Louvre is overcrowded, overhot and overamped. Go early, have a plan, and avoid wandering aimlessly, because that way lies madness (along with sore feet). After my latest visit, I recovered with a crêpe by the fountains next to the pyramid. If the Louvre sells out, my post on small Paris museums has some excellent consolation prizes.

Tier 4: Book a Few Days Ahead

These rarely sell out months in advance, but the best time slots still go early.

14. The Acropolis, Athens

When to book: Every ticket has a one-hour entry window, and there’s a daily cap. In summer, book the 8 am and 9 am slots at least two weeks ahead. Afternoon slots usually have space a few days out.

I climbed in September, and it was less onerous than I’d feared, mostly because the crowds force everyone to climb slowly. If it’s hot, consider a late afternoon slot when the crowds thin, the temperature drops and sunset is on the way.

15. Notre-Dame Cathedral, Paris

When to book: Entry is free, and free reservations open two days ahead on the official website. Tower visits are separate, cost extra and open about three months ahead.

I arrived at 4:10 with my reservation and walked straight in with zero waiting. To my left, a very long line snaked around several loops. I couldn’t figure out why anyone would skip the reservation, since it was so simple. Note that your slot is only valid for twenty minutes, and more reservations are released throughout the day.

Sold Out? Don’t Panic

• Check the official site again. Cancellations reappear, and several sites (the Eiffel Tower and the Vatican among them) release extra tickets. Early morning is often the best time to look.
• Book a guided tour that includes entry. Tour companies hold their own ticket allocations, so a small-group tour can get you in when the official site says no. You’ll pay more, but you’ll usually learn more too.
• Try for same-day tickets where they exist. Neuschwanstein releases a limited number each morning, and the Galleria Borghese occasionally sells leftover places at the ticket office.
• Watch out for lookalike resale sites. Some third-party sites are designed to look official and charge well above face value. Buy from the official site or a reputable tour company.
