Doolin Cave is home to a wondrous geological phenomenon - The Great Stalactite. Measuring almost 7 metres in length, it is one of the largest free hanging stalactites in the world and the longest stalactite in the northern hemisphere. What makes it even more impressive is the fact that it is held on by a section of calcite, less than 0.3 m square.

Visitors to Doolin Cave will experience an unforgettable adventure. You will become an explorer, donning a hardhat and flashlight as you make your way through the 100m long cave. The chamber housing the sparkling Great Stalactite is subtly lit, to highlight its delicate but awesome splendour.

Visitor numbers are limited, with no more than 20 visitors per tour. Access to the cave is via courtesy coach from Brauch Na Haille Restaurant Doolin Village.

Admission: EUR 20 (adult), EUR 50 (family).
