As well as stunning, unspoilt scenery the region also offers a huge gastronomic tradition (truffles, foie gras and confit being some of the most famous local produce) and fantastic local wines.

Days can be filled by sampling the dark, heady wines of the Cahors region. Hundreds of vineyards can be found in the countryside, many of which have been producing wine for centuries and are happy to offer free tastings.

The area between the valleys of the River Dordogne and River Lot is amongst the most beautiful in the world, with an array of things to do and see, including exceptional prehistoric sites, medieval villages and a huge range of sporting activities.

History
This region was part of the battlefield of the Hundred Years War, thus many of the castles, villages and towns were built by the English.

Chateau Beynac
This middle ageconstruction, with its austere appearance, is perched on top of a cliff, dominating the town and the north bank of the river Dordogne

The route of St James/ St.Jacques (The GR652 route to St Jaques passes Mas de Flory)
Shortly before the year 900AD the tomb of St. James / St.Jacques / Santiago the Great / Major / Elder was ‘discovered’ in the part of Spain known as Galicia. The news rapidly spread throughout Christian Europe and very soon pilgrims were making their way from all parts of the continent to visit the site. As Spain is a part of the Iberian Peninsula, this meant that at some time most of the travellers would have to make the hazardous journey across the Pyrenees. Many routes led to the crossing point from places further north and east, like so many tributaries feeding into a river. The badge of these pilgrims is the scallop shell, known in French as the coquille St.Jacques.

Rocamadour is both a place of pilgrimage and a tourist attraction with its shrines and chapels which cling precariously to the side of a cliff. Visitors reach the pedestrianised town by a "road train" where they will find artisans shops, restaurants and a toy museum. The views from the village are stunning. Rocamadour boasts one of only thirty cheese Appellation d'Origine Contrôlées (A.O.C's.) in France with its goat's cheese.
Nearby there is a monkey preserve which you can walk around and see over 100 Barbary Macaques who are only too happy to relieve you of the popcorn you can purchase at the entrance.

Domme
Dating from 1283, the bastide of Domme overlooks the Dordogne from the South and is quite simply one of the most beautiful places from which to admire the view. The golden stoned village is crammed with small artisans' shops and is extremely well preserved.
You can visit the underground cavern under the covered market where the village's population hid during the Hundred Years' War and the Wars of Religion.
Domme is a little larger than many of the bastide towns, and is found perched high above the Dordogne River, with  wonderful views of the river and countryside. Unusually among the bastide towns, Domme retains part of its original fortified walls and the gateways into the town.
Perhaps the overly perfect restoration and over-commercialisation of the town reduces the feeling of authenticity that is found in, say, Monpazier. However a visit remains a 'must'.
There are also some very good caves accessed from the centre of Domme. The town is also listed as 'one of the most beautiful villages in France'

La Roque Gageac
Surrounded by ancient manors and crowned with cliffs, La Roque mirrors itself in the waters of the Dordogne river.
It was an important fortified place in medieval times, the village adorned itself with rich manors in the Renaissance period, such as Jean tarde’s manor. The village streets blossom with tropical and mediterranaean plants.

The Gouffre de Padirac is a natural chasm 75 metres deep formed when the vault of a limestone cave collapsed into the underground river below. The tour begins with a descent by lift (or stairs for the more energetic!) 103 metres to the river and then proceeds with an underground boat trip which takes visitors to the cathedral-like Grand Dôme which is 94 metres high. The tour lasts about one and a half hours and covers 2km.

St. Cirq Lapopie was the first place in France to have a preservation order on the entire medieval village.

Les Eyzies
The prehistoric site of Les Eyzies includes the Musée Nationale de Préhistoire which is to be found in a 13th century castle perched above the village. The museum contains a large number of artefacts dating back in some cases more than 15,000 years. Nearby the Grotte de Font de Gaume and the Grotte des Combarelles contain a fine collection of prehistoric art including bison, reindeer, magic symbols and carvings.

Sarlat-la-Canéda
Sarlat-la-Canéda is a medium sized market town whose roots go back as far as a Benedictine abbey founded in the 9th century but which came into its own during the 13th. Following the Hundred Years War Charles VII rewarded Sarlat's population for its loyalty against the English through a number of tax exemptions and gifts. The fruits of the  resulting reconstruction in the middle of the 15th century are still visible today.
The myriad of boutiques and souvenir shops will keep a visitor busy for hours and in the evening, the gas lighting enhances the character of the town no end. Sarlat's market, held in Place de la Liberté on a Saturday, is renowned as one of the best in France.

The Knights Templar
The Knights Templar were formed after the first crusade, in the late Middle Ages, to capture the Holy Land (Palestine and Israel) from the Infidel1. They received the foundations of the ancient Temple of Solomon2 upon Mount Moriah in Jerusalem where they established their headquarters.

The Crusades
Their founder, Hugh de Payens, and his nine knights vowed to protect the overland path from the sea to the city of Jerusalem. For the first nine years of their existence however, they dug beneath the ancient temple, excavating an ancient network of tunnels. The Ark of the Covenant3 was supposed to be housed in this temple before the city was sacked by eastern invaders.

It's thought that the Knights Templar come across some ancient knowledge while they were excavating that may have originally come from Egypt or, as some have hypothesised, Atlantis.The knowledge was in the form of many things but most noticeably, to those in the Middle Ages, architecture. Gothic cathedrals sprung up throughout Europe in designs never seen before, one of the first being Chartres which employed flying buttresses. This is an architectural design feature which allowed for more space in the interior of churches and larger stained glass windows.

The Templars became extremely powerful over rather a short period of time, mostly thanks to the work of the priest named Bernard de Clairvaux (later St Bernard), who introduced them to Pope Honorius II, who eventually made them answerable to only him.

Upon their return to France, armed with what they had found, they grew strongly in number, gathering great quantities of gifts in lands and titles. Noblemen and peasants alike flocked to join the ranks of these knights who would then grant their own lands to the Order in the spirit of the brotherhood. Many noblemen who didn't want to join a crusade donated their lands to the cause in exchange for a quick passage to Heaven.

Cahors AOC wine
The appellation has been named after the city of the same name, which is the capital of the Lot department in south-western France. The vineyard area totals around 4.500 hectares, the vineyards are located on both banks of the Lot river, to the north-west of Gaillac. The wine-growing region is one of the oldest and also one of the most famous in France. The Celts, or Gauls as they were known here, produced oak barrels here as early as the 6th century BC.
Cahors is one of the oldest and yet least known french wines, the red wine of Cahors has a long a distinguished history. Cahors belongs to the Quercy region, a part of France considered by National Geographic and many others to be one of the worlds ‘unspoiled and undiscovered earthly paradises’

Chateau Chambert
Chateau Chambert produces wines that show both generosity and refinement, due to their balance between tannins, fruit and acidity. The vineyard is located on the highest part of the Cahors plateau, in south-western France. This specific terroir lends additional elegance to the natural intensity of Chambert’s wines. Cahors is the homeland to the Malbec grape.
