7 Paris Sights to Book in Advance (and 5 NOT to)

Planning a trip to Paris? Then you’ve probably asked yourself: What do I actually need to book in advance?

And that’s a smart question.

Because yes — some tickets in Paris disappear fast and if you’re not online at the right moment, they’re gone. I wish I was exaggerating.

And yet, the idea of planning every hour weeks ahead? Not exactly how I like to travel either. Who really knows what they’ll feel like doing on day two in Paris?

But here’s the good news: you don’t need to reserve everything.

After 20 years in Paris, helping visiting friends plan their trips, and hearing from travelers stressed because key sights were already booked out, I’ve learned which reservations really matter — and which ones don’t.

Some sights require strategy. Others let you decide on the spot. The trick is knowing the difference.

7 Things to Book in Paris (And What You Can Skip)

Before I get into the specific sights you should reserve in advance, here’s one rule I always follow:

If something is truly on your bucket list — a museum, a restaurant, a landmark — book it as soon as you can.

Those once-in-a-lifetime experiences aren’t worth gambling on. If you’d be disappointed to miss it, secure it and move on. So here are the top things to book in Paris — and what you can leave flexible.

Extra Tip: If you prefer Paris at a calmer pace, I created a guide called Paris Without The Overwhelm with my favorite crowd-avoidance strategies, planning help and ways to enjoy the city without the chaos. Explore the guide here →

#1 The Eiffel Tower

Eiffel Tower Summit and Second Floor Access: check availability for your dates

If your trip to Paris would feel incomplete without going up the Eiffel Tower, don’t leave it to chance.

Tickets — especially lift access to the summit — are released 60 days in advance at midnight (Paris time). And once they’re live, they can disappear fast.

I learned this the hard way when I tried to book tickets for a weekend visit with my kids. I kept checking just a few days in advance — and every single time, everything was already sold out. Completely hopeless.

That’s when I realized: this is one of the main things to book in advance in Paris.

Stair tickets to the second floor are usually released 14 days in advance and tend to last a bit longer, but they can still sell out during peak season.

→ If visiting the Eiffel Tower matters to you, book it as soon as your dates are fixed.

Sold out! Here’s what I’d do

If the official website shows no availability, you still have two realistic options:

1. Try for onsite tickets
Sometimes tickets are available at the tower on the day — but there’s no guarantee. Lines can easily stretch to two hours or more, no matter the weather.

Personally, I’d only try this if you have flexibility and don’t mind the wait — especially with kids, it can be a bit of a gamble.

2. Book a guided tour (best backup option)
When everything looks sold out, tours on platforms like GetYourGuide or Viator often still have access.

They cost more — but you:

• avoid the longest lines
• get a smoother entry
• and you can be sure you can visit

👉 If I had to plan this again last-minute, this is the option I’d choose.

Best options if tickets are sold out

If your dates are fixed and nothing is available on the official site, these are usually the easiest alternatives:

→ Eiffel Tower Summit or Second Floor Access
→ Eiffel Tower Summit & Seine Cruise Combination

👉 Best for: first-time visitors or families who don’t want to risk missing out

#2 The Louvre

Louvre Timed Entry & Tour: check availability for your travel dates here

The Louvre is the most visited museum in the world, welcoming more than 9 million visitors each year. It’s busy year-round — and often sold out.

If you want a specific date and time, book in advance. Either directly through the museum’s official website or via a → guided tour (which is often the smoother option).

I’ve entered the Louvre both through the regular queue and through the group tour entrance — and the difference is huge.

With a standard ticket, I waited far longer than expected just to get inside. With a guided tour, the entry was significantly faster and much smoother.

---

Why I usually recommend a guided tour

Even when standard entry tickets are sold out, guided tours frequently still have availability. That’s why I often suggest considering a tour — especially during high season.

Important update: Since 2026, ticket pricing differs for EU and non-EU visitors. Because of this change, standard Louvre entry tickets are no longer sold via third-party platforms like GetYourGuide. Guided tours, however, are still available.

This is exactly why I now prefer booking a tour:

• You can often book earlier — or even last minute
• You enter through a separate entrance with significantly shorter waiting times
• You save significant time in the museum
• Most importantly, you get context from an expert guide — which truly matters in a museum this massive

👉 If you don’t want to risk wasting time in line, this is usually the easiest way to secure entry:

→ If your dates are fixed and tickets are limited, this is the option I’d personally book

#3 The Château de Versailles

Versailles Palace & Gardens Full Access Ticket: check availability for your travel dates here

Versailles is the most popular day trip from Paris — and for good reason. It’s easy to reach, incredibly impressive, and on almost everyone’s must-see list.

If you’re planning to go, booking in advance makes a big difference.

Why timing matters at Versailles

During summer and on weekends, the best time slots — especially in the morning — sell out quickly. They’re simply the smartest choice: you explore before peak crowds and can head back to Paris by mid-afternoon.

I once chose a later time slot thinking it wouldn’t matter — but by the time I arrived, it was already extremely crowded, and getting through the palace took much longer than expected.

This is exactly why I now always aim for an early entry:

• Morning entry = fewer crowds
• A much smoother experience inside the palace
• More flexibility for the rest of your day

👉 If you want to avoid the busiest hours, book an early time slot here (Same price as booking directly, but with a much simpler checkout process.)

Easiest option from Paris

If you don’t want to deal with train schedules or organizing everything yourself, guided tours with transport are a very convenient alternative.

👉 If you prefer something simple and stress-free, this is the easiest option from Paris

#5 The Catacombs of Paris

Paris Catacombs Entrance & Audio Guide: check availability for your travel dates here

Note: The Catacombs are closed for renovation until spring 2026.

The Catacombs, an underground ossuary holding the remains of over six million people, are one of the most unique — and also one of the most popular — sites in Paris.

Because capacity is extremely limited, booking in advance is essential. Only 200 visitors are allowed inside at a time, and time slots fill up quickly.

The Catacombs are actually on one of my regular cycling routes — and every time I pass by, the sign outside says “complet” (sold out).

What makes planning a bit tricky is that official tickets are only released 7 days in advance. In practice, that means:

• same-day availability is extremely rare
• tickets are often gone almost immediately
• and buying onsite is usually not an option

If this is something you really want to see, I wouldn’t leave it to chance.

👉 If your dates are fixed, this is the easiest way to secure your spot in advance

#6 Michelin Star & Fine Dining Restaurants

If your trip to Paris is the perfect excuse to experience the creations of some of the city’s most celebrated chefs, planning ahead is essential.

I’ve tried booking popular restaurants before — and more often than not, everything was already fully booked for days, if not weeks.

A good example is Septime, one of the most well-known Michelin-starred restaurants in Paris that’s relatively “affordable” for its level.

Reservations open just 3 weeks in advance — and even knowing that, I tried for months to get a table without success. It’s a bit easier now than it used to be, but when it was at its peak hype? Completely hopeless.

One tip that makes a big difference

If dinner reservations are unavailable, try booking lunch instead.

Lunch menus are often:

• just as high quality
• easier to secure
• more affordable

What I’d do: If there’s a specific restaurant you really want to try, don’t wait.

👉 Check availability as soon as your dates are fixed — the best places fill up incredibly fast.

Easy alternative (if you didn’t plan ahead)

If you don’t want to organize reservations in advance — or everything is already booked — food tours can be a great alternative.

👉 If you still want a memorable food experience without the hassle, this is a great option to consider

5 Activities in Paris You Don’t Need to Reserve

But despite all the buzz, the crowds, and the need to reserve certain activities in Paris, there’s plenty of wiggle room. And in Paris terms, this means time to wander, explore, go with the flow and truly enjoy Paris.

I like to think of Paris trip planning in two categories:

• the essentials: 1 or 2 activities a day that are fixed on your itinerary
• the extras: hidden gems, cafés, parks, and smaller museums that you can sprinkle around as you feel it.

And, these extras don’t require either a reservation or planning. Here are 5 Paris activities that you don’t need to reserve.

That said, even these flexible activities sometimes have optional upgrades if you want to make them a bit more special.

#1 Seine Cruises on one of the Bateaux Mouches

Personally, I’m a big fan of Seine Sightseeing Cruises and still think they’re one of the best things to do in Paris.

Cheesy and touristy? Yes. Relaxing, beautiful, and surprisingly magical? Also yes.

And the best part: you don’t need to lock them into your schedule weeks in advance.

Standard sightseeing cruises run every 30 to 60 minutes, depending on the season. You can simply show up and hop on — whether it’s a Bateau Mouche near Pont des Invalides or a Bateaux Parisiens departure close to the Eiffel Tower.

If lines look long, just walk a little further. The Vedettes du Pont Neuf are another great option. Or take the Batobus— which stops at multiple locations along the Seine — is perfect if you want flexibility.

I’ve done this completely spontaneously before — just walking up, boarding the next boat, and it ended up being one of the most relaxing parts of the day.

When you should book in advance

That said, not all cruises are as flexible.

If you’re interested in something more special — like a lunch cruise, dinner cruise, or champagne experience — those usually need to be booked ahead.

• 2- Hour River Seine Lunch Cruise: This is what I’d book
• Private Boat Cruise with Champagne: View prices here
• Champagne Tasting Cruise from the Eiffel Tower: View prices & availabilities

#2 The Musée Carnavalet

See here my list of free museums in Paris

Everyone knows the Louvre and the Musée d’Orsay. But Paris has around 130 museums — and most of them don’t require advance reservations.

The Musée Carnavalet is one of them. It’s dedicated to the history of Paris and, even better, permanent collections are free to visit. No timed-entry stress. No weeks-ahead planning.

I’ve popped in here a few times on a whim — and it’s always been one of those unexpectedly rewarding visits, especially when you want a break from the crowds.

Inside, you’ll find everything from medieval artifacts to Revolution memorabilia, restored historic rooms, paintings, and photographs that trace the story of the city through the centuries.

If you want to understand Paris beyond the postcard version, this is the place. And you can simply decide on the day whether you feel like going.

Optional: make it more structured

If you prefer a bit more context while exploring the Marais, you can also combine a visit with a guided walking tour of the area.

👉 This is a great option if you want to explore the neighborhood with a local guide

#3 Montmartre

Also read my Montmartre Guide to know what awaits you

Montmartre is the former artist district in the north of Paris — and it still feels like a village within the city. This is not a place for strict planning. It’s a place for wandering.

I’ve spent hours here just walking without a plan — and it’s one of the few places in Paris where getting a little lost actually feels like the point.

Spend a slow morning here. Or an entire afternoon. Get lost on purpose. Climb a few stairs. Pause for coffee. Let the streets lead you.

You’ll naturally come across the highlights: Sacré-Cœur, the Musée de Montmartre, Place du Tertre, La Maison Rose, Rue de l’Abreuvoir. They reveal themselves as you explore.

The neighborhood itself doesn’t require reservations. Just show up.

(If you’re planning to eat at La Maison Rose, though, that’s one of the few places where booking ahead makes sense.)

Optional: if you want more context

If you’d like to understand the history and hidden corners of Montmartre a bit better, a guided walking tour can be a great addition.

👉 This is a great option if you want to explore Montmartre with a local guide

#4 The Panthéon & the Arc de Triomphe

Paris has many impressive landmarks that are absolutely worth visiting — but they’re not quite as competitive as the Louvre or the Eiffel Tower.

Many visitors simply walk by, take photos, and move on. And that’s exactly why these are the kinds of attractions you don’t usually need to book in advance in Paris.

I’ve done both — walking straight in and occasionally waiting a bit — and most of the time, the lines move much faster than you’d expect.

Places where this applies

• The Panthéon
• Arc de Triomphe
• Tour Montparnasse
• Invalides

There might be a short queue, especially on weekends. But lines generally move quickly, and you can decide on the spot whether you feel like going in.

When I’d still book ahead
That said, if missing one of these would genuinely disappoint you — or if you’re visiting during a busy period — booking ahead can still be worth it for peace of mind.

#5 Brasseries, Bouillons & Bistros

Here’s my guide on traditional Bouillons Restaurants in Paris

Is the culinary side of Paris on your bucket list?

The good news: the weeks-in-advance reservations mostly apply to Michelin-starred and hyped fine dining restaurants.

If you’re dreaming of steak tartare in a classic brasserie, traditional dishes in a bouillon, or a simple croque monsieur on a terrace, you can usually decide on the spot. Paris has no shortage of good options.

I’ve done this many times — just walking around until something looks good, sitting down, and it often ends up being one of the most enjoyable meals of the trip.

One quick tip: I always check Google ratings, and anything above 4.3 is usually a safe bet.

You’ll find restaurants everywhere. And if you’re unsure whether a place is genuinely local or more of a tourist trap, take a quick look at the menu. If it’s translated into five languages and offers 30+ dishes from onion soup to pizza to sushi, that’s usually a sign to keep walking.

Otherwise? Sit down. Order something simple. Enjoy.

Good to know: Traditional Bouillons usually don’t even take reservations, you just queue and wait your turn. The exception are the Bouillon Pigalle and Bouillon République.

Wrap up: Plan the Essentials, Leave Room to Wander

Voilà, that’s Paris trip planning in a nutshell.

Yes, a few things are absolutely worth booking ahead — especially the ones you’d be disappointed to miss. But no, you don’t need to schedule every hour of your stay.

Secure the essentials. Leave space in between.

That’s how you avoid missing out — while still giving yourself time to wander, linger on a terrace, or change plans because something catches your eye.

What I’d personally do

If I had to plan a trip to Paris again, I’d book just a few key things in advance:

• the Eiffel Tower (if going up is important to you)
• the Louvre or Musée d’Orsay
• Versailles (with an early time slot)

For me, these are the main things to book in Paris before your trip. And then leave the rest flexible.

Paris rewards a little structure. But it rewards spontaneity even more.
Bon voyage.
