Discover Doolin Cave, an extraordinary underground caving experience in the Burren, County Clare. Take a fully guided tour of one of Europe’s most compelling cave attractions, and go over 200 feet under the limestone of the Burren landscape. Travel back in time over 350 million years and see how the Burren was formed. You’ll journey through a system of passages before emerging in a large chamber which is home to one of the greatest natural wonders of the world, the Great Stalactite - which was once beautifully described as “the palest gleam in the darkest deep”. It is the longest free-hanging stalactite in the northern hemisphere! At 7.3 metres long and weighing an estimated 10 tonnes, it naturally suspends from the cave ceiling like a chandelier. It is hard to believe that this enormous calcite formation was formed from a single drop of water over hundreds of thousands of years. Take the opportunity to experience the third-largest stalactite in the world, on a Doolin Cave Tour!
