hi - am off to the Lot - south of the Dordogne - in 3 weeks and am planning on driving over to the Pech Merle prehistoric caves from other side of Cahors, went to them about 20 years ago but can't remember what the road was like. anybody been there that can tell me please, also thinking of going to St Cirq le Popie but realise its going to be heaving that time of year, is there likely to be parking for motorhome on outskirts - thanks for any possible info
