Is the Paris metro safe?

I’ve ridden the Paris metro at every hour, on every kind of day, and I want to separate two questions that get mixed up constantly: is the network itself dangerous, and is Paris after dark unsettling in places. Those are different questions. This page is only about the first one — the trains, the platforms, the turnstiles, the tunnels. If you’re looking for how I handle Paris at night on the street, that’s covered separately in is Paris safe at night; here I’m staying underground and on the The Paris metro, explained: how to read the map and find your way system itself.

What the network actually is

Paris runs one of the densest urban rail systems I’ve used anywhere: 16 metro lines crisscrossing the city, plus 5 RER lines that stretch out into the wider Île-de-France region, all coordinated by Île-de-France Mobilités. Trains run close together, stations are frequent, and on most lines you’re rarely waiting long. I use the Paris metro tickets and the Navigo guide to keep a Navigo Easy card loaded and don’t think about it much beyond that.

Statistically and in my own experience, this is a safe way to move around. I don’t mean that as reassurance — I mean it the way I’d say a subway in any major European capital is safe: staffed stations, security presence, other passengers around you at almost every hour on the lines that matter to visitors. Violent incidents involving tourists on the metro are genuinely rare. What isn’t rare is petty theft, and that’s where I put my attention.

The real risk: pickpockets, not danger

If something goes wrong for a visitor on the Paris metro, it’s almost always a phone or a wallet, not a threat to personal safety. Crowded cars are the classic setup: someone brushes past as the doors are closing, a bag is unzipped in the two seconds you’re distracted by the platform announcement, a phone slips out of a back pocket while you’re wedged in at rush hour. I keep my bag on my front in dense crowds and I don’t put a phone in a back pocket, full stop — that’s the whole strategy, and it works. For the broader picture of scams and pickpocketing across the city, not just underground, I’ve written up the patterns in Paris scams and pickpockets.

Two spots on the network deserve specific mention, because they come up again and again in what I hear from other travellers and in my own trips.

Line 1 is the one I’d flag first. It runs east-west through the densest tourist corridor in the city — Châtelet, Louvre-Rivoli, Bastille — and it’s often standing-room-only during the day. High ridership plus a lot of visitors carrying bags and cameras is exactly the combination pickpockets look for. I don’t avoid the line; I just keep my bag zipped and in front of me when it’s full.

RER B is the other one, mostly because it also serves Paris Charles de Gaulle (CDG) airport, which means it’s carrying people with luggage, jet lag, and unfamiliarity with the system all at once — an easy target profile. I’ve used CDG airport to Paris city centre: RER B or taxi dozens of times and never had an issue, but I keep a hand on my bag through the crowded central Paris stretch of that line the same way I would on line 1. If you land at Orly instead, the calculus is the same on line 14 into the city, just with fewer people carrying luggage since it’s a shorter, more local line.

Beyond those two, I don’t treat any particular line or station as a no-go. The system as a whole is fine; it’s crowd density that raises the risk, and crowd density moves around by time of day more than by line.

What I actually do, station by station

Nothing complicated. I keep valuables in a zipped inside pocket rather than an outer one. I don’t check my phone with it half out of my pocket while standing near the doors. On a packed platform waiting for a delayed train, I stay aware of who’s standing close, the same instinct I’d use in any crowded transit system. None of this is Paris-specific caution — it’s the same habits I’d use on a packed train anywhere.

I also don’t do the opposite mistake, which I see visitors make: treating every stranger on the metro as a threat, gripping a bag white-knuckled, refusing to make eye contact with anyone. That’s not necessary and it’s not how the vast majority of my rides have gone. Most people around you are commuters getting to work, students, other visitors — not looking for an opening.

For the RER lines that run through the wider Île-de-France region, the calculus doesn’t really change. I’ve taken RER C out toward Versailles: how to visit the palace, gardens and Trianon from Paris and RER A out toward day-trip territory without incident, and the same basic rule applies: stay aware in crowded central segments, relax more once the train empties out past the city. For a longer look at how the whole regional network fits together, see Paris RER and trains guide.

Late at night on the network

This is worth separating out because it’s a genuinely different situation from daytime crowding. Late-night trains run less frequently and carry fewer people, which can mean nearly empty cars. I’ve found that riding closer to the conductor’s car, staying near other passengers rather than in an empty carriage, and having my route planned before I go underground (so I’m not standing on a platform checking a map for ten minutes) covers most of what matters. If a train or platform feels genuinely empty and I have another option, I’ll sometimes take it — but that’s a judgment call, not a rule, and it applies as much to night trains as it does to any quiet public space.

Practical planning that helps

A few habits that reduce friction more than they reduce risk, but they add up: I check Paris RER and trains guide before a day trip so I’m not improvising a transfer with a bag full of gear. I keep my ticket or Navigo Easy accessible rather than digging for it at a barrier. And when I’m heading out to Champagne day trip from Paris: Reims and Épernay houses to visit or up to a guided day out to Giverny and the Van Gogh villages, I plan the RER leg into central Paris the night before rather than working it out half-asleep at 7am.

For museum-heavy days that involve a lot of metro hopping between sites, I’ve found a multi-day museum pass also cuts down on how much time I spend standing in ticket lines with a bag out — fewer transactions, less time distracted in a queue. It’s a minor safety upshot, not the main reason to get one, but it’s a real one.

If a taxi feels simpler for a late arrival or a heavy suitcase, I don’t second-guess it — see Taxis and ride-hailing in Paris for how that compares. Most of the time, though, I default to the metro or RER, because it’s genuinely the faster and more reliable option across the city, and the safety trade-off is smaller than people expect.

The bottom line

I ride the Paris metro and RER constantly and I don’t think about safety much beyond ordinary crowd awareness. The system itself — the trains, the stations, the staff — isn’t the risk. Crowded cars are, specifically on line 1 and on RER B where it serves CDG, and specifically for pickpocketing rather than anything more serious. Keep your bag zipped and in front of you in a crowd, keep your phone out of a back pocket, and the Paris metro is exactly as safe as its ridership numbers suggest.

FAQ: Paris metro and RER safety

Is the Paris metro dangerous at night?

Not dangerous in the sense of violent crime, but trains run less often and cars can be emptier, so I stay near other passengers and have my route planned before heading down.

Which metro line has the most pickpocketing?

Line 1 comes up most often, because it runs through the busiest tourist corridor and is frequently packed during the day.

Is RER B safe from CDG airport?

Yes, it’s a normal and widely used route into Paris. I keep a hand on my bag through the crowded central-Paris stretch, mainly because it carries a lot of luggage and jet-lagged travellers, which draws pickpockets.

Should I avoid certain metro stations?

No specific station is a no-go. Crowd density matters more than any one location — stay aware in packed cars and on full platforms rather than avoiding a station outright.

Are there security staff or police on the metro?

Île-de-France Mobilités staffs stations and there’s a visible security presence on the network, particularly at major interchange stations.

Is it safe to use my phone on the metro?

It’s fine, but keep it firmly held rather than loosely out near open doors on a crowded train, which is when quick grabs happen. Tapping in with contactless is generally fine too — see can you use contactless on the Paris metro for how that works.

Is the metro safer than taking a taxi?

For most trips inside Paris, the metro is faster and the safety difference is minimal. A taxi can make sense late at night or with heavy luggage, but it isn’t a safety necessity for ordinary daytime travel.

Do I need to worry more on the RER than the metro?

Only in the sense that RER trains cover longer distances with fewer stops, so a crowded central segment (like RER B near the airport) deserves the same crowd awareness as a busy metro line. If you’re weighing RER B against a taxi straight from CDG, I’ve compared the two directly in RER B or taxi from CDG airport.

Is the metro accessible if I have a stroller or limited mobility?

Accessibility varies a lot by station — some have lifts, many older ones don’t — which is more of a planning issue than a safety one. I go through it station by station in Paris metro with a wheelchair or stroller.
