My husband and I are planning a trip to Dordogne in late May-early June for about 2 weeks. We plan to fly into Bordeaux then drive to Les Eyzies de Tayac area. Is this a good place to stay for a week or so while visiting several of the caves in the area with prehistoric art? Which are the best caves to see, and should we reserve in advance? I looked at Grotte de font-de-gaume, Grotte des combarelles, La Grotte de Rouffignac, and Lascaux II. I also really wanted to walk on a medieval town wall and wondered if there were any towns/villages in the area which had accessible walls or ramparts we may traverse. Also, how is the road from Bordeaux to this area? Should we plan to spend 1 night in Bordeaux after an overnight flight from the US? Please advise. Thanks very much.
