Your First Day in France: Make or Break Your Trip

Stepping off the plane at Charles de Gaulle is one of those moments that feels both thrilling and slightly terrifying.

You’re jet-lagged. You don’t know which way to walk. And approximately 47 things need to happen before you can collapse into your hotel room.

Let me walk you through what those 24 hours actually look like, what to do first, and the one mistake that catches almost every first-timer at the gate.

The Immigration Line Is Slower Than You Think

CDG sits 25 kilometers northeast of Paris. You’ll arrive exhausted, and your first real obstacle is passport control.

Since October 2025, France participates in the EU’s Entry/Exit System (EES). As a non-EU visitor, your fingerprints and a facial image get registered on your first Schengen entry. The process adds time, and it’s new enough that lines are still figuring themselves out.

The average wait at CDG immigration runs about 37 minutes. During the morning “bank” — when transatlantic overnight flights all land between 6 and 9 a.m. — that can stretch to 90 minutes.

Build that into your plans. Don’t schedule anything tight for your first morning.

Don’t Touch That Airport SIM Kiosk

You’ll walk through arrivals and see kiosks selling SIM cards. Skip them.

CDG has no official operator shops. What you’ll find are resellers, and they charge significantly more than you’d pay elsewhere.

The smarter move: buy an eSIM before you leave home. Airalo has France plans starting at $4. Holafly offers unlimited data from about $19 for five days. You scan a QR code on your home WiFi, the eSIM sits dormant on your phone, and the moment you land in Paris, you’re connected.

Install it at home. Activate it when you land. That’s it.

If your phone doesn’t support eSIM, the Orange Holiday physical SIM is available on Amazon and ships to U.S. addresses before your trip.

The Ticket That Gets You Fined at the Airport

This one matters.

Since January 2026, a single Paris metro, RER, or train ride costs €2.55 — flat rate, anywhere in the city. Paper tickets are gone as of mid-2026. You load your ticket onto a Navigo Easy card (€2 at any station machine) or use the Bonjour RATP or Île-de-France Mobilités apps on your phone.

But that €2.55 ticket does not work at airport stations. Using it at CDG will get you bounced at the gate or fined.

To get from CDG to central Paris by RER B, you need the Paris Region Airports ticket: €14 per person. It covers the 40-minute ride to Châtelet-Les Halles and includes onward metro transfers for two hours. Buy it on the Île-de-France Mobilités app before you land, or at the machines in the station.

The RER B runs every 10-15 minutes from 5 a.m. to midnight. One more thing: the RoissyBus shuttle was permanently discontinued in March 2026. Some older guides still list it. Ignore them.

If you have a lot of luggage, traveling late at night, or don’t want to deal with stairs and crowds on your first day, a taxi costs €56 to the Right Bank or €65 to the Left Bank at a fixed rate.

Planning a trip for spring 2027 or later? The CDG Express opens March 28, 2027 — a 20-minute non-stop train to Gare de l’Est, running every 15 minutes. Ticket price is expected around €24. Not an option today, but worth knowing.

Cash: Yes, But Not Much

Paris is nearly fully card-friendly in 2026. Bakeries, restaurants, pharmacies — most places accept contactless payment for any amount.

That said, bring some cash. Around €60 to €80 for the week is plenty.

Do not exchange dollars for euros at the airport or at currency exchange shops. The rates are punishing. Use a bank ATM once you’re in the city and withdraw from your checking account. The machines will try to offer you a “cash advance” option — ignore it. That’s a credit card transaction with fees attached.

Some smaller shops and markets require a minimum purchase (usually €10 to €15) to use a card. A few coins and notes in your pocket avoids any awkward moments.

Your First French Meal

You’re hungry, you’re disoriented, and there are restaurants everywhere. Resist the ones with giant backlit photos of food and menus in five languages.

Once you’re in the city: walk at least two blocks away from any major landmark before choosing a restaurant. The food gets exponentially better and cheaper within one minute of walking.

Dinner in France doesn’t start until 7 or 8 p.m. If you arrive in the afternoon and need to eat earlier, brasseries serve all day. A great first option: Bouillon restaurants like Bouillon Chartier or Bouillon Pigalle, where a full three-course meal costs under €20.

One thing that surprises every visitor on day one: the server will not bring your bill. Ever. You ask for it. “L’addition, s’il vous plaît.” Say it confidently. They’re not being rude — that’s the system.

Tap water is free. Ask for “une carafe d’eau.” If you just say “water,” you’ll likely get a €4 bottle.

The Jet Lag Trap

You’ve been awake for 20 hours. Your hotel room is calling.

Don’t nap.

Get outside, find sunlight, walk a few blocks, eat something. If you absolutely must sleep, set an alarm for one hour and nothing more. Sleeping three hours on day one will flip your schedule against you for the rest of the week.

The RER B drops you at Gare du Nord or Châtelet. Both are central, walkable, and full of cafés. Get a coffee. Find a bench. Let France happen to you.

You’ll feel human again by dinner.
