Torca del Carlista

Torca del Carlista is a cave in Karrantza Valley containing one of Europe's largest underground chambers, carved out from surrounding limestone rock. The main chamber rises dramatically from the cave floor, showing layers and formations that reveal the valley's geological history.

The cave was discovered in the mid-20th century when regional speleologists began systematically exploring the limestone formations of Karrantza Valley. Their investigations revealed this hidden underground space that had remained sealed beneath the surface for countless centuries.

Local communities maintain protective measures for the cave system while supporting scientific research and controlled speleological expeditions.

Visiting requires specialized caving equipment and experienced guides familiar with the underground environment. Trips are typically organized in advance to ensure safety and proper preparation for the cave conditions.

The underground chamber ranks among the largest in Europe, appearing like a natural stone cathedral carved over millions of years. Its massive scale makes it a geological wonder that remains relatively unknown to most visitors.
