Doolin Cave

Ireland's beautiful Doolin Cave may have had a controversial beginning as a popular attraction but now thousands of people a year flock to this tiny town to take a look at the Great Stalactite.

Originally known as "Pol an Ionain" the craggy limestone cave has been known to spelunkers for decades. However it was not until the 1990s that the subterranean treasure was made accessible to the public. Despite objections from caving enthusiasts, the tight and treacherous entrance to the cave was expanded and a door was placed over the aperture. The interior of the cave was also built out to allow for lay visitors. However after opponents of the plan took the cave owners to court it was decided that no visitors center could be built on the land to keep traffic a bit lower. 

All turmoil aside the cave was eventually opened, introducing the world to the Great Stalactite, one of the biggest free-hanging formations of its kind in the world. The giant ceiling spike reaches down almost 20 feet from the cave's roof, an impressive creation created by dripping water and thousands of years.

The cave grounds also feature a peaceful nature walk through the lush Irish landscape.
