Last time i go it was about 1 year ago, the hole to the quarry was open. i dont plan to go there anymore but i give you the tips to reach the hole, wich is called the cat flap:
you can go down on the railway right here, near the metro station Alesia or tramway L3 jean Moulin: http://i.imgur.com/zacL5hi.jpg
the entry point to the railway: http://i.imgur.com/x9hR84Z.jpg the door is closed, you must jump over the wall.
then you follow the direction of the arrow. as you reach the 3th tunnel, a big one, the hole is somewhere on your right. if you reach the other exit of the tunnel, you’ve gone too far: http://i.imgur.com/s5xLlwQ.jpg
if you go saturday night, you can meet people but i recommand you to not go down if you dont have map.
