Park in the large car park at Lascaux IV.
(S/E) Walk along the main road (Avenue de Lascaux), which gradually climbs up the hillside to a fork in the road on the left.
(1) Leave the road and take the path (GR®® 461) on the left, which cuts through the forest, then cross the road to take the road opposite, which passes in front of Lascaux II. You can see the entrance to the real Lascaux Cave on your right, through the fence. Continue along the road.
(2) Shortly after passing the "Domaine de Lascaux", take a fairly inconspicuous path on the left, marked by a post and a yellow arrow (PR®®). Follow this path, which descends gently until it meets the road below.
(3) Turn left, follow the road to a crossroads and turn left to return to the car park (S/E).
