Depart from your accommodation in Bordeaux and drive two hours east into the heart of the Dordogne valley, where nature meets quaint medieval villages and romantic castles. The first spot you'll visit is Montignac, home of Lascaux IV, a prehistoric cave where you can see some extraordinary Paleolithic rock paintings. Afterward, head to Sarlat, a medieval village that has more historical buildings per square foot than anywhere in France. If you visit on a Wednesday or Saturday, you’ll also get to see its famous local market. You'll have some free time to stroll around and have lunch, then travel to Beynac, one of the prettiest villages in France, where a warren of narrow, cobbled streets leads to a 12th-century castle scenically perched atop a limestone cliff.
