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/

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.

The most prominent natural monument is undoubtedly the Cliffs of Moher, a dramatic geological feature stretching for approximately 14 kilometers along the Atlantic coast. Other notable natural monuments in the wider region include the Cuilcagh Boardwalk Trail (Stairway to Heaven), the Cuilcagh Mountain Summit, and Slieve Rushen, all offering unique landscapes and experiences.
The Cliffs of Moher are composed of Namurian shale and sandstone layers, formed over 320 million years ago. You can see evidence of a buried ancient river channel and the dramatic effects of wind and sea erosion. The area is part of the Burren and Cliffs of Moher UNESCO Global Geopark, highlighting its significant geological importance.
Yes, O'Brien's Tower, a 19th-century gothic-style stone tower, offers elevated panoramic views from near the highest point of the cliffs. From here, you can see the Aran Islands, the Maumturks, and the Twelve Pins mountain ranges. Hag's Head, at the southernmost point, also provides a quieter viewpoint.
The Cliffs of Moher are a crucial nesting ground for seabirds, designated as a Special Protection Area (SPA). They host Ireland's largest mainland colony of nesting seabirds, including puffins (from April to July), guillemots, kittiwakes, razorbills, and fulmars. Marine life such as whales, basking sharks, dolphins, seals, and otters can also be spotted in the waters below.
The Cliffs of Moher are spectacular year-round, but for the best chance to see puffins, visit between April and July. Generally, late spring and summer offer milder weather for hiking and exploring the various natural monuments, though the weather can be unpredictable at any time of year.
Many of the natural monuments offer accessible pathways and viewing platforms suitable for families. While some trails, like parts of the Cuilcagh Mountain Summit, can be challenging, there are often easier sections or alternative routes. The eco-friendly visitor center at the Cliffs of Moher also provides interactive exhibitions for all ages.
Policies regarding dogs can vary. While some areas might allow dogs on leads, especially on public trails, it's always best to check specific regulations for each natural monument before your visit. For example, the Cliffs of Moher visitor center advises caution and specific guidelines for pets.
The region offers diverse hiking experiences. You can explore the cliff trails at the Cliffs of Moher, which are part of a longer coastal path. For a unique experience, the Cuilcagh Boardwalk Trail leads across impressive moorland to a summit plateau. You can find more hiking options in the area by exploring the Hiking around Moher guide.
