Marble Arch Caves Fermanagh
The Marble Arch Caves in County Fermanagh are the finest showcaves in Ireland and one of the most important cave systems in the British Isles, a complex of limestone caverns explored from 1895 onward that provides one of the most spectacular underground experiences in Ireland. The boat journey on the underground river through flooded passages provides the most memorable introduction to any show cave in the country. The caves form part of the Marble Arch Caves UNESCO Global Geopark.
The show cave experience begins with a boat journey through a flooded section of the cave system, the guide navigating the low passages above the underground river while the cave ceiling reflects in the still water below. The subsequent walk through the decorated caverns, with stalactites and stalagmites of considerable variety, provides a comprehensive tour of formations accumulated over hundreds of thousands of years.
The Geopark encompasses the remarkable karst landscape of Cuilcagh Mountain, including the Cuilcagh boardwalk trail sometimes called the Stairway to Heaven for its dramatic ascent to the mountain plateau. The combination of caves and surface landscape creates one of the most complete geopark experiences in Ireland.
