I have been told there is a vineyard in the Montmarte area but I can't find it on any of my Paris maps. Can anyone help with location and info? Thanks

It is a very small vineyard, on a slope about the size of "1/2" a block. It is at the corner of rue des Saules and rue St Vincent, diagonally across from Cimetiere St Vincents, and across street from Lapin Agile. Another way to pinpoint it is to see location for Sacre Coeur, then St-Pierre church, then the vineyard kind of lines up, then the cimetiere. That should do it!

It's a really tiny vineyard!

If I'm not mistaken is closed to the public except for harvest, when there's a wine sale to raise funds.

It is right out in the open, has a fence (maybe a chain-link kind of fence) - you can see it plainly from the street. Don't know if there is anyone in attendance to speak to; the annual harvest is 1st weekend in October, and they hold a small celebration.

The Lapin Agile itself is worth a look too.
