Who knows what the first inhabitants of the Grottes de Sare, some 20,000 years ago, would make of today's whiz-bang technology including lasers and holograms during sound-and-light shows at these caves. Multilingual 45-minute tours take you through a gaping entrance via narrow passages to a huge central cavern.
Follow the D306, 6km south of the village of Sare. Le Basque Bondissant (www.basquebondissant.com) runs buses from St-Jean de Luz to the caves €2; (bus 868) a couple of times a day in summer.
