The Great Stalactite is supported by a single point of attachment to the cave ceiling.
The cave remains at a constant temperature of approximately 11 degrees Celsius year-round.
It is formed in the Carboniferous limestone of the Burren region, which is known for its glacial-era landscape.
The 7.3-meter stalactite is the longest of its kind in the Northern Hemisphere.
The cave was found by following the sound of an underground stream through a narrow fissure.
The weight of the Great Stalactite is estimated to be over 10 tonnes.
The cave features a stream that eventually connects to the local water table.
Development for tourism was delayed for decades to ensure the preservation of the delicate interior environment.
Doolin Cave is home to the Great Stalactite, one of the world's longest free-hanging stalactites, measuring 7.3 meters in length. The cave system is located in the karst landscape of the Burren in County Clare. Visitors descend 100 steps underground to view the limestone chamber. The formation was discovered in 1952 by cave explorers J.M. Dickenson and Brian Varley. The cave is an active system, meaning it contains flowing water and ongoing mineral deposition. It is unique for its isolation from other nearby cave systems. The site includes an eco-trail on the surface for observing native Burren flora.
From the designated viewing platform at the end of the descent, which provides the clearest angle of the Great Stalactite.
Wear a waterproof jacket as the cave environment is consistently damp with dripping water.
Arrive early in the day during peak summer months to avoid large tour groups.
Bring sturdy, closed-toe footwear suitable for walking on uneven, wet limestone surfaces.
Do not expect to wander freely; access is strictly restricted to guided tours for conservation purposes.
Closed annually for a period in mid-winter; check official website for exact seasonal closure dates.
Do not touch the stalactites, as oils from human skin can stop their growth and permanently discolor the formations.
