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.

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.

The Cuilcagh Mountain Park sprawls 6,170 acres (2,500 ha) on the northern slopes of the spectacular Cuilcagh Mountain. Founded in 1998, the park works to conserve the bogland habitats and restore damaged peatland. Towering at 2,188 feet (665 m), the mountain is one of the highest points of Ireland. The limestone rock was formed over 300 million years ago from the remains of tiny sea creatures when what is now Ireland would have been covered by a shallow tropical sea.
