Volvic stone is a trachyandesite formed approximately 11,000 years ago during the eruption of the Puy de la Nugère.
The stone was widely used to construct many buildings in Clermont-Ferrand, including the Cathedral of Our Lady of the Assumption.
The underground galleries span several thousand square meters, revealing the historical 'tunnels' left behind by local stonecutters.
The site illustrates the transition from artisanal stone cutting that began in the 13th century to industrial-scale extraction.
Volvic stone is prized for its aesthetic versatility, ranging from polished finishes to intricate carvings used in decorative art.
The Grotte de la Pierre de Volvic is an underground quarry located in the volcanic landscape of the Auvergne region. It highlights the extraction history of trachyandesite, a grey-black volcanic stone known as Volvic stone used in regional architecture. The site features a self-guided circuit through subterranean galleries created by centuries of stone extraction. Visitors observe the evolution of quarrying techniques, from manual tools to modern mechanized methods. The site is situated within the volcanic park of the Chaîne des Puys, a UNESCO World Heritage site. Interactive exhibits explain the geological formation of the volcanic rock following eruptions from the Puy de la Nugère. The temperature inside the cave remains consistently cool throughout the year regardless of the season. Displays also demonstrate the specific physical properties of the stone, such as its porosity and frost resistance.

Bring a warm jacket, as the underground temperature remains low even during the peak of summer.
Wear comfortable, flat walking shoes with good grip, as the floor can be uneven.
Check the website for current seasonal closure dates before planning your visit.
Do not attempt to visit without checking the operating calendar, as the site periodically closes for maintenance or off-season periods.
Closed annually during the winter months and occasionally on Mondays or Tuesdays depending on the season.
Maintain a quiet volume to respect the acoustics of the stone galleries; do not touch or remove loose rock.
