Metro #4 at Gare du Nord

So....when I arrive on March 21, how do I get from CDG to Montmartre (Abbesses)? Do I have to go past GdN and Chatelet and then turn around and head North?

The 4 was not really the line to Montmartre anyway. There are several lines serving Montmartre, but the best way from Nord is usually to get the #2 metro at LaChapelle reached within the station in a long walk down well signed corridors. Just follow the round blue circles with '2' in them. When you get to LaChapelle, take the escalator up to the platform with Porte Dauphine as the end point. This line skim along the base of Montmartre from Barbes, to Anvers to Pigalle to Blanche. You can transfer to line 12 at Pigalle to get to Lamarck Caulaincourt or Abbesses. Or if you actually need the 4 to Chateau Rouge, you can transfer at Barbes. Abbesses is not on line 4.

Sorry. I didn't make myself clear. I know Montmartre isn't on Line #4, but I've always taken the RER B line down to GDN, and then picked up the #4 going north, and from there, #2 to #12 and off at Abbesses. My question is: if I can't get off at GDN, what's the best way to wind my way to Montmartre (Abbesses metro stop).

I don't know if this will work for you.

Bus #54 in front of the Gare du Nord to Pigalle where you can catch the Montmartrobus to Abbesses.

Along those same lines how would one get from Gare du Nord to Etienne Marcel and vice versa? The article seems to read that other stations are closed. Where would I find out about that?

@ larlock, you can plan out your trip at ratp.com/en. This is the site run by the RATP. If there is a planned outage or a problem on your date of travel, it will offer directions that exclude the line with the problem. You can get directions now and then check it again on your travel date in case a line is not running because of an emergency.

@ kateja, Gare du Nord is closed for Line 4. It's not closed for all trains so the RER B will still stop there. Just get off at Gare du Nord and follow the instructions that Janet gives you above to pick up line 2 at La Chapelle and then connecting to Line 12. That's the way I would go even if Line 4 was running from Gare du Nord. It will be a little bit less walking to take Bus route 54 but the transfer will not be free unless you have a Navigo pass.

Kateja. I gave specific directions for getting to Abbesses in my response that you dismissed. 4 was always a bad choice, you would be changing metro twice that way i.e. 4 to 2 to 12 -- why would you do that instead of going 2 to 12. Every change requires lugging baggage up and down metro stairs.

Walking to Montmarte and Abbesses from Gare du Nord takes about 20 mins.

I apologize to Janetravels. I wasn't trying to be snarky. I'm just a little stressed. So as I understand it. Even though the #4 line doesn't stop at GDN, the RER B train from CDG will. So I can still get off at GDN and catch the #2, or walk (which might be the best solution after an overnight flight). My daughter is taking the train down from Amsterdam. I was hoping to head off any confusion on her part.
Thanks all.

JHK, don't you mean ratp.fr/en/ ?

If you have data to use, or stop in somewhere with WiFi, the RATP app, "Next Stop Paris" will give you the best real time directions including walking maps and metro connections.

@ darcy, Yes I do. Thank you for the correction. 😃

@ Kateja....Re: your question if you can't get off at GDN, no problem with that. You won't be the only one getting off at GDN. The RER B ends there, or it always stops at Nord.

When I am in Paris, ie, land at CDG, I always take the RER B to Nord, (cost 10 Euro), where I get off since my small hotel is conveniently located right there. Gare du Nord is a junction point for 2 Metro lines and several bus lines which either stop in front of the station or on Rue St Quentin near the Chinese restaurant "Le Jumbo."
