The caves contain occupation layers with evidence of flint tools from the Mousterian, proto-Solutrean, Creswellian and Maglemosian cultures. They were seasonally occupied by nomadic groups of people during the Upper Palaeolithic and Mesolithic periods. Evidence of Neolithic, Bronze Age, Roman and post-medieval activity has also been found there. There is evidence of Neanderthal occupation 50,000–60,000 years ago, a brief Gravettian occupation around 32,000 years ago and use of all the main caves during the Magdalenian around 14,000 years ago. The site is open to the public and has a visitor centre with a small museum of objects associated with the caves, including a stuffed cave hyena.
