The castle played a significant role during the Hundred Years War, as the border between the troops of France and England was along the Dordogne River. In this castle sat the French, and on the other side, in the castle Castelnau, the British. It can be seen in the distance, in the center of the next photo.
At the foot of the castle, on the banks of the river, is the village of Beynac-et-Cazenac. It is very small, you can eat in the restaurant and make a beautiful photo near the river. Parking is here N 44 50.395 E 1 08.470.
From the village you can go up to the castle (map), but if you are traveling by car, then this does not make sense, since there is also parking near the castle.
Find on the official website opening hours and ticket prices.
Getting there: parking near the castle at the top N 44 50.468 E 1 08.822. Nearest railway station is Gare de Sarlat, 10 kilometers away.
