VIA CAHORS From the autoroute A20, follow the signs to CAHORS. Take the turn off for CAHORS SUD. After leaving the peage you will drive down a long straight road at the end of which you should turn right towards Cahors. As you approach Cahors, you will come to a roundabout – take the D653 to AGEN. After another 6 miles take the road to Agen which forks to the right. Take this road, the D656 and about 14 miles further on you will bypass the bastide town of TOURNON. (If you have come across country from, say, SARLAT, via FUMEL, you will join the D656 here.) Continue towards Agen and after about 6 miles you will come to a big crossroads. Turn to the left, the D47 towards MONTAIGU-DE-QUERCY winds downhill for about 2 miles. At the end you will come to a T-junction, take the right turn towards BOURG-DE-VISA. Follow the D7 towards BOURG-DE-VISA for another 5 miles by ignoring all the signs towards BEAUVILLE! Colombe-de-Mathieu is on your left just before a small lake and 1 mile before BOURG-DE-VISA.
