In reply to Kramma:
I don't think Vieux-Château can be considered a classic area but it's lovely nonetheless, long sustained routes (about 70 I reckon?) on excellent granite, mostly in the 4-5-6 (very little in terms of 7s and above). Can get crowded on weekends though. It's a nice change from the limestone that otherwise abounds in the area.
Saussois is extremely polished up to 6b and will be darn hot in the coming weeks/months (it's supposed to hit 36C next week) as it faces south, same with Rochers du Parc. If it's really hot I believe Saffres would be the best option (though I haven't been). Also consider Cormot: long routes on blocky limestone with a mountain feel, put up as early as the 30s, a bit intimidating, sparsely bolted in the mega classics. The 5s are amazing. Mostly grades 5-6-7. The setting is great too (the drive up or down, not so much!).
