Hidden in woodland 18km north of Les Eyzies, this unusually large, wide cave system includes 8km of tunnels on three levels, of which visits cover around 1000m by electric train. Highlights include a rare frieze of 10 mammoths, and the "Great Ceiling" with more than 65 figures from ibex to aurochs. You’ll also see 17th-century graffiti and the dens of long-dead cave bears.
Buy tickets in person at the cave entrance on the day of your visit. In July and August arrive by 9am to get tickets for any time that day, but in other months afternoon tickets are only available after 2pm.
