Been years since I was on holiday around there, we stayed in Argens-Minervois. I can remember doing a ride South from there, on the D212, through Lagrasse, onto the D3 to Monze, and then turning right up some brutally steep single carriage road passed Château de Miramont and then down the other side and back to the villa.
I was hopelessly over geared on that holiday and never made it as far as Pic de Nore. I did a few rides up the valleys nearby though, taking in Citou, Cassagnoles and Minerve. Basically, head up a valley, turn left or right, come back down the next one, loop back.
