La Mare aux Corneilles
Sure you heard about Pirouette Cacaouette, this enough is of course a good reason to visit the area. But there are a lot more around. This is a quiet and outspread area, you might meet someone at Pirouette, but often that's it. The other problems are though worth a visit. For a training day, have a look at Le toit Cornélien. This roof has more training problems than an average climbing gym, all roof climbs. The area is not really family friendly. Paths are somewhat non-existing for most problems. You can find problems stretching from really easy to 8A+, so most people can enjoy a few days in this area.
Here are some good ones to check out:
La Cicatrice de l'Ohm 8A+
Pirouette Cacaouette 7C
Rio Bravo 7C
Coup de Chaleur 7B
Grand Reef 7A
Jet Stream 7A
6 Clones 6C+
Le toit cornélien 6B+
Angleterre à Terre (debout) 6A+
Just to mention a few. There might also be some sneaky first ascents possible.
It's recommended to download this guide offline, reception is mostly bad around the area.
