Sarlat is a beautiful town to visit. Set in the region called the Perigord Noir in the Sout West of France. Wander round the quaint little streets or stop for a coffee in the Place de la Liberté and just soak up the atmosphere. I would highly recommend visiting Sarlat on market day where the stalls are set up along the main street and around the old town. The Rue de la Republique runs the length of the old town, with lots of narrow streets on either side.
There are a good variety of shops in Sarlat which makes it worth a visit at any time. You can park in the main carpark next to the centre or if it is market day use the car park up the hill and wander down into the town through the church grounds, it only takes about ten minutes. (maybe slightly longer on the way back)
You will find plenty cafes to have lunch or morning coffee. Take a walk up the hill from the square on Rue Fenelon and wander along Boulevard Henri Arlet and turn down Rue Montaigne. You will come to the old Lanterne des Morts have a look inside at the structure.
Wander back down towards town and look out for the quaint little houses.
