"continual slur on Irish caving" It's actually only a few hundred metres is accessible and it's total length is thought to be 2km. No where near the longest cave in Ireland. Consider a trip in only if well equipped with a good light and helmet. Alternatively/also consider visiting McKenzies back lounge just down the road. A much drier watering hole. ;)

Stunning limestone caves which you can explore on a guided tour. Well worth a visit. There are 150 steps down to the caves so if you are wearing cleats please be aware, or change into a pair of trainers before you descend down into the natural wonder. There is also a cafe on site. For further details please see https://marblearchcaves.co.uk/

Pollnagollum Cave (meaning Hole of the Dove) is the longest cave system in Ireland. The cave system is complex and fascinating and is fed by a tumbling waterfall that topples off a limestone cliff. Watch your stepping here as rocks can be unstable and slippery, and don't forget your camera for some awesome shots.

Beautiful cascading waterfalls along Cuilcagh Way, situated at the foothills of Cuilcagh Mountain. These multi-tiered waterfalls are a delightful sight as you wind through a forest of lichen, ferns, and wild seasonal bluebells.

Yes, several natural monuments are suitable for families. The Ancient Chestnut Tree is located along an estate trail, offering an easy walk. Forthill Park, with its monument and clock tower, is also considered family-friendly, featuring paved paths and shrub gardens. While the Marble Arch Caves offer guided tours, parental discretion is advised for very young children due to the 150 steps involved.
The area is rich in geological wonders, particularly limestone formations. The Marble Arch Caves are a prime example, being part of a UNESCO Global Geopark and showcasing spectacular underground limestone caves formed by rivers. Pollnagollum Cave also features a complex cave system fed by a waterfall tumbling off a limestone cliff.
Absolutely. The Marble Arch Caves are situated within the Cuilcagh Lakelands, a UNESCO Global Geopark known for both its geological and cultural heritage, with human habitation dating back over 7,000 years. Further afield, the Giant's Grave & Giant's Cave in Burren Forest feature megalithic tombs intertwined with local Irish folklore. Queen Medb's Cairn on Knocknarea, though not directly in Skreen, is a massive Bronze Age burial mound dominating a natural mountain, offering superb views and a profound connection to ancient history.
Many natural monuments are excellent starting points for walks. For example, the Cascades Waterfall is found along the Cuilcagh Way.

Accessibility varies. The Marble Arch Caves require navigating 150 steps.

Forthill Park offers paved paths, making it more accessible. Always check specific highlight details for the most up-to-date information on terrain and accessibility.
The natural monuments can be enjoyed year-round, but each season offers a different experience. Spring and summer bring lush greenery and warmer weather, ideal for exploring trails and waterfalls like the Cascades Waterfall. Autumn showcases beautiful foliage, while winter can offer a stark, dramatic beauty, especially around sites like the Cuilcagh Boardwalk Trail. For cave systems like Marble Arch Caves, the experience is largely consistent regardless of the season, though booking in advance is always recommended.
