The Cuilcagh Boardwalk Trail, affectionately known as the "Stairway to Heaven," offers a challenging yet rewarding hike through one of Northern Ireland's most stunning landscapes. Spanning approximately 11 km round-trip, the trail meanders through expansive blanket bogs before culminating in a steep ascent of 450 wooden steps to a viewing platform atop Cuilcagh Mountain. Hikers are treated to breathtaking panoramic views of the surrounding lowlands, including glimpses of counties Cavan, Leitrim, and Donegal on clear days. While the boardwalk was constructed to protect the delicate bog ecosystem, it has also made the trail more accessible, attracting over 60,000 visitors annually.

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!
