In a couple of weeks time, I'm off to the Loire by Eurostar + TGV, which means a cross Paris change. The Eurostar uses Gare du Nord, while the TGVs down to the Loire are at Gare Montparnasse.

One option is to take a taxi, but that looks to be around the €30 mark.

There is a direct metro line linking the two stations, M4, which would seem to be a great bet. Unfortunately, the metro station isn't really at Gare Montparnasse, but is instead a 750m+ walk with lots of stairs. With a load of luggage, that's not looking much fun...

If I want to do the transfer by public transport, is that my only bet? Or is there another route (perhaps by bus?) that'll let me get from one station to the other by public transport, but without lots of walking?

As Andra said, RER B (5 stations) + Metro (3 stations) will be way faster than Ligne 4 all the way down. The thing is the interconnection Line 4 to the train can take you up to 10 minutes, more if you have luggage with you. But taking the line 6 from Denfert-Rochereau to Montpartnasse will save you this time, trains are at the first exit.


Gare Du Nord -> RER B -> Denfert Rochereau -> Line 6 -> Montparnasse Bienvenue

Enjoy your trip and welcome to France :)


The Montparnasse-Bienvenüe metro station is practically two stations with a long corridor between them: lines 4 and 12 to the north, and lines 6 and 13 to the south. The train station is on the south side, so whenever you're boarding a train it's best to arrive by line 6 or 13. (Here line 4 is still faster if you're an average walker with no luggage, and you won't incur any extra stairs, just extra corridors.)

From Gare du Nord, the best rail connection is RER line B southbound (take any train heading in the right direction). Change at Denfert-Rochereau for metro line 6 towards Étoile (the interchange corridor is near the middle of the platform on line B IIRC). You will have to go up and down a few staircases. Plan on 30–50min from TGV platform to TGV platform, not counting any queue to buy tickets.

If you want to avoid staircases altogether (apart from a few escalators to reach the trains at Montparnasse), you can take the bus. There's no direct line between Gare du Nord and Montparnasse, and there are many combinations with one change. Off-peak, plan on 50–70min from platform to platform, not counting any queue to buy tickets. At peak hours, the bus can get stuck in traffic for a very long time (less so between the second Sunday of July and the next-to-last Sunday of August). There is also not much room for luggage on the bus, so I don't recommend it at peak hours. An advantage of the bus is that you can go to Montparnasse 2 TGV instead of Gare Montparnasse; Gare Montparnasse get you close to the rear of the train, while Montparnasse 2 TGV gets you close to the front of the train. A good combination to have the option to go to Montparnasse 2 is line 38 (departs from Gare du Nord so you don't have to worry about direction), then change at Port-Royal for line 91 (towards Montparnasse).

A taxi will be more expensive than public transport, but the 30€ figure feels large. I'd expect about 15€ off-peak on a weekday (more at night or on week-ends; 30€ might be reached if you get stuck in traffic).

    Paris taxi drivers, even those picking you up at an airport or train station, tend to act as though they have never seen or heard of suitcases before and you are irrational for having them with you. There is much wringing of hands and asking for extra fare. Perhaps that's where the 30 comes from? Commented Jul 11, 2011 at 16:57

    About the M4 option : not only the corridor walk is long, but there also are some flights of stairs. The connection begins with narrow corridors where it is difficult to take over other travelers pulling their suitcases at normal walking speed in case of a hurry, followed by moving sidewalks.

    Bus line 91 was extended in the last big shake up of the bus network and now runs from Gare du Nord to Gare Montparnasse, though taking quite a detour via Gare de Lyon, so it takes a little while. Add to that the fact that there are often scheduled busses not actually running and that makes it a viable option only if you have plenty of time.

You can take the line 4 BUT exit directly and walk in the open air. It's not so long and doesn't have any stairs.


It doesn't help this exact question, but it might help somebody else reading this as part of planning a trip - in the current timetable there are a few direct TGVs from Lille-Europe station to stations on the LGV Atlantique such as Nantes or Rennes, and changing at Lille-Europe on the outbound is as simple as getting off the Eurostar and finding the platform for the onward train with no need to cross Paris. Even on the return, being able to get off the train and then go through passport control etc at the same station is a win over having to cross Paris only to do the same at the Gare du Nord.

    I changed at lille Europe on my trip to Marsellie a few years ago and would reccomend this option. The extra width on the TGVs compared to the Eurostars makes them far more comfortable IMO. Commented Dec 27, 2023 at 15:02

Take the RER B and change to the M6 line at Denfert-Rochereau. This connection is much faster then the M4.

  • Is the walk any better, or is it just a faster route? (Faster's good of course!)

    Andra is right but take the line 6 at Denfert-Rochereau and not the 4, the correspondance Train - Line 6 is way much shorter that Train - Line 4. You'll save you at least 7-10 minutes.

  • @Spredzy that looks like the trick, and chance you could promote that to an answer so I can accept?

A little trick usable only from Nord to Montparnasse : take line 4, but don't get off at Montparnasse, get off at Raspail. Line 6 to Etoile is at same level, avoiding two flights of stairs. It reduces the walk as line 6 station is nearer from Montparnasse station.


Line M4 went fine for me as a direct connection between the Gare du Nord and the Gare Montparnasse. I did not have much luggage with me though, just a rucksak, a laptop and a small trunk. But enough space in the metro M4 to carry all that. Just take care that you take the M4 in the right direction. Ask people around you if you don't know, preferably in french. Some might answer in English. They are very helpsome. In 20 minutes I travelled from the platforms of the Gare du Nord to the platform in Montparnasse for the TGV to Rennes capital of Bretagne. I came from Brussels that day with TGV as well. I started at 10h00 in Brussels and was in Rennes at 14h30. Not bad, because there was a strike going on that day at the SNCF. But only 25 % of the Union members joined that strike, which is something I have never seen before in France. I was lucky.

  • To ask people in French is not a really helpful advise for most of us, I think. But the signs are pretty obvious, I always memorize the end stations of the direction I need to go to. Also helped me on this transfer.

  • Gare Montparnasse please, will be understood by most.

  • -1. RATP gives 17 minutes for the 14 metro stations between Montparnasse and Gare du Nord. So unless you are the kind of guy who runs 1000m in 3 minutes (plus buy a metro ticket, plus wait for your metro, etc.) 20 minutes seems Impossible.
