Mauriac for 1 week in June – what to do??

We are staying in a friend’s holiday cottage in Fignac (near Anglards-de-Saler) from 16th-23rd June, and wondered if anyone had any recommendations of what to see and do in this area? We would be willing to travel a couple of hours to see / do something special, but generally would like to stay locally (less than 1 hours drive from here). I am hoping to have a bit of a chill out holiday (unlikely, but fingers crossed) so would mainly be interested in relaxing things to do, like visiting town / cities, castles, good restaurants / vineyards etc.

We fly in and out of Toulouse and will have a hire car, and have the option of staying over somewhere else on our last night, preferably somewhere in the direction of the airport, so may be Toulouse!

Any thoughts or recommendations would be greatly appreciated.

Thanks
