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.

Great walk, very touristy but it's worth the detour! Be careful of the crowds (on weekends and in summer I dare not imagine!). However, BE CAREFUL, the summit is not accessible, you have to pass the protective barriers which allow the wild nature to be preserved from our steps and from this crowd of people. If we, the Komoot community, start to do this all the tourists will allow themselves and the landscape will never be so beautiful again! (Ps: no need to climb to the top to already see enough in the eyes!)

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/
