Incredible Stone-Age park, with some technical trails. Massive mythological sacred stones worshipped over centuries, will follow you when adventuring into this unique geological and archaeological forest landscape.

"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. ;)

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.

Clodagh Glen has a steep sided gorge that is lined by ancient ash trees that cling to the steep sides. The water sculpted river valley has a spectacular arch over the river which formed when the cave roof collapsed. The reserve is known for its limestone gorge, mystical caves and beautiful waterfalls. In the springtime the valley floor is carpeted by bluebells, wood anemones and wild garlic and in the summer silver-washed fritillaries are found besides the path. With a keen eye you may also spot an elusive pint martin and red squirrels!

Many of Ireland’s megalithic monuments—portal tombs, court cairns, or wedge tombs such as this one—are known locally as “the giant’s grave.” But this one, on a hilltop in Co. Cavan’s Burren Forest Park, has a giant story to go along with its name. According to Harold Johnson, from the nearby town of Blacklion, the giant, attempting to impress a lady, failed in his final attempt to jump the nearby chasm, which is, of course, called “The Giant’s Leap.” Harold Johnson relates this story in some detail, while seated on the Giant’s Grave, in the video, below right. Mr. Johnson also was our guide, and provided the narration, for our feature on the Killinagh Cursing Stones, located on the opposite side of the town of Blacklion.
