Marble Arch Caves - Explore Spectacular Underground Rivers, Limestone Formations and Natural Wonders in County Fermanagh

Marble Arch Caves is one of Northern Ireland's most spectacular natural attractions, located near Florencecourt in County Fermanagh. Set beneath the beautiful foothills of Cuilcagh Mountain, this remarkable cave system offers visitors an unforgettable journey through ancient limestone passages, underground rivers and magnificent rock formations.

The caves are part of the Cuilcagh Lakelands UNESCO Global Geopark, an internationally recognised landscape celebrated for its outstanding geological heritage. The surrounding limestone was formed more than 340 million years ago, creating the foundations of the fascinating underground world visitors can explore today.

Marble Arch Caves is recognised as one of the most active river show caves in Ireland and the United Kingdom. Over thousands of years, flowing water has carved an extraordinary network of chambers, passages and underground waterways beneath the Fermanagh countryside.

Visitors can discover this hidden world on a guided cave tour, following specially constructed pathways through beautifully illuminated passages. Knowledgeable guides explain the geology, history and natural processes responsible for creating the spectacular underground landscape.

One of the highlights is the impressive collection of stalactites, stalagmites and delicate limestone formations. These remarkable natural features have developed gradually as mineral-rich water passes through the rock.

The underground rivers are another fascinating feature, with flowing water continuing to shape the cave system. Depending on water levels and weather conditions, some tours may include a short underground boat journey.

The caves were first explored scientifically in 1895 by French cave explorer ?douard-Alfred Martel and Irish naturalist Lyster Jameson. Their pioneering expedition helped reveal the extraordinary scale and significance of the underground passages.

Marble Arch Caves opened to the public in 1985 and has since become one of County Fermanagh's most popular visitor attractions. The guided experience provides an exciting combination of natural history, geology and underground exploration.

Above ground, visitors can enjoy the beautiful surrounding landscape, which features ancient woodland, waterfalls, rivers and scenic walking trails. The peaceful countryside provides opportunities for photography, nature watching and outdoor adventures.

The visitor centre also offers a virtual reality cave experience, providing another way to discover the underground environment. This can be particularly appealing to visitors who are unable to participate in the traditional guided tour.

Guided cave tours are suitable for many families and visitors, although the underground environment includes steps, slopes and uneven surfaces. The caves remain cool throughout the year, so warm clothing and sturdy footwear are recommended.

Admission charges apply for guided cave tours, and advance booking is strongly recommended, particularly during school holidays and busy periods. Ticket prices and tour availability can be checked on the official website.

The visitor centre generally opens from 9am to 5pm, although cave tour schedules and seasonal opening arrangements may vary. Underground tours can be affected by heavy rainfall and high water levels, so visitors should check conditions before travelling.

Visitor facilities include parking, toilets, a gift shop and information about the surrounding UNESCO Global Geopark. Accessibility arrangements vary between the visitor centre and the underground cave system.

The underground cave tour is not wheelchair accessible because of the natural terrain and numerous steps. Visitors with reduced mobility should contact the attraction before booking to discuss available experiences and facilities.

Dogs are not permitted on the underground cave tours, except for assistance dogs where suitable arrangements can be made. Visitors should check the attraction's current animal access policy before travelling.

Nearby attractions include the spectacular Cuilcagh Boardwalk Trail, Cladagh Glen Nature Reserve and the beautiful Florence Court estate. The wider Fermanagh Lakelands also offers opportunities for walking, scenic drives and exploring Northern Ireland's natural heritage.
