The simplest way: by road.
You can also take the A10 (E606) or A89 (E70) ... the it will remain a few kms to go through the county.
By train, St Aigulin, but especially Coutras Libourne (35kms) if you come from Paris ... and then a taxi will take home.
By plane, Bordeaux-Merignac is 70 kms from our place, Bergerac 55 kms and Angouleme 67kms ... then a taxi.
