The quarry is open all year round, free of charge. A trail punctuated by interpretation panels allows visitors to explore the quarry on their own. The Mollets quarry is of fundamental historical and scientific interest in the Poitou-Charentes region. A testimony to past human activity, the Mollets open-cast quarry was mined for its limestone and fed a lime kiln built nearby. Although activity ceased in the 1950s, the old quarry is still of scientific interest. The quarry face exposes three successive Jurassic geological formations, representing almost 15 million years of sedimentary records. The site is also classified as a Sensitive Natural Area (ENS). Free guided tours are scheduled every year (see L'Homme et la Pierre program) or by appointment all year round.
