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!

The Cuilcagh Mountain Park covers 6,000 acres on the north slopes of the Cuilcagh Mountain. The park was founded in 1998 and works to conserve the bogland and restore damaged peatland. At 665m the mountain is one of the highest points in Ireland. The Limestone rock was formed over 300 million years ago by ocean calcifying organisms when Ireland was covered by shallow tropical sea. With an interesting and varied flora and fauna alongside historic ancient ruins, there is plenty to explore in the park.

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.
