Grotte di Pastena
About
The Pastena Caves (Grotte di Pastena) are a karst limestone cave system located in the municipality of Pastena, in the province of Frosinone in the Lazio region of central Italy. They lie approximately 4.5 km southeast of the town, accessible by a short drive along the road to Castro dei Volsci. Since their discovery in 1926 by the geologist‑entrepreneur Carlo Franchetti, the caves have been opened to the public and have become one of the most popular underground attractions in Lazio. The cave complex is divided into two distinct parts: the active “inferior” section and the older “fossil” superior section. The active zone is still alive with dripping water that has formed a spectacular gallery of stalactites, stalagmites, flowing streams and a small underground pool. The fossil zone, by contrast, preserves an array of calcite formations that have remained unchanged for millennia, offering visitors a glimpse into the long‑term geological evolution of the region. Guided tours are available in Italian and English, and an onsite visitor centre offers informational exhibits that explain the cave’s formation, its significance in speleology and the local biodiversity found within its chambers. For families and school groups, the accessible pathways and audio‑guide options make the Pastena Caves an engaging educational destination. As part of the Consorzio Grotte Pastena e Collepardo, the caves are managed with a focus on sustainability and conservation, ensuring that every visitor can enjoy the beauty of the speleothems while protecting the delicate underground ecosystem for future generations.
