I spend a lot of time near Beziers and there's a load of climbing around.
La Clape is decent and not too polished. Caroux is wonderful. Plenty other decent smaller crags nearby too. If you can get further afield you have Claret and Thaurac, which are pretty major.
There's a Facebook group for climbing in the area - a search for "Climbing - Escalade - Grimper: Tautavel; Opoul..." will find it for you. Beziers also has a climbing club - Club Megalithe. Between these you should be able to find someone to get out with.
It's a bit warm in the summer though! 40+ on several days last summer.
