Hi Phil,
I've got an older pdf topo for Le Cardou - drop me a mail if you'd like a copy (I can't e-mail you through the site)
I don't know the crags around there very well, but I have had an afternoon in the Gorges de Pierre-Lys (at Cavirac), but I don't think that the sectors really count as family friendly. But it was cool enough to climb in the summer. This will almost certainly not be the case at La Clape.
Targasonne is a bit of a drive away, but it's not actually that far to drive over to Ax les Thermes (via Belcaire) for a trip to the Orlu boulders or even the crags around Tarascon.
There's also the incongruously large climbing wall at Belcaire if it rains.
