Overview
Cuilcagh (Irish: Cuilceach or Sliabh Chuilceach) rises to 665 m (2 188 ft), making it the highest point in both County Fermanagh (Northern Ireland) and County Cavan (Republic of Ireland). The mountain sits at the heart of the Cuilcagh Lakelands UNESCO Global Geopark, a trans‑national protected area that stretches from Lower Lough Erne in the north to Lough Oughter in the south. Its flat‑topped summit is cloaked by one of Western Europe’s largest intact blanket bogs, while the lower slopes expose limestone, mudstone and sandstone that record some 340 million years of geological history.
History & Background
The name Cuilcagh is traditionally translated as “chalky”, a nod to the limestone outcrops on the mountain’s northern flanks despite the predominance of sandstone and shale. Human activity dates back to the Neolithic, and a prominent Bronze‑Age cairn crowns the summit plateau, dating from 2 500 – 500 BC. During the 1609 Plantation of Ulster the land was granted to John Sandford and later sold to Toby Caulfeild, 1st Baron Caulfeild. Modern conservation began in 1998 when Fermanagh District Council opened Cuilcagh Mountain Park; in 2001 the area became part of the Marble Arch Caves Global Geopark – the world’s first trans‑national Geopark. The mountain is protected as a Special Area of Conservation, a Ramsar wetland, and an Area of Special Scientific Interest.
Getting There
- By car: The main trailhead is the privately‑run car park on Marlbank Road (often called the Legnabrocky car park). A smaller farm‑track entry is available from the north side of the mountain. Both car parks have limited spaces; arriving early in the high season (May‑September) is advisable.
- Parking fees: The Legnabrocky car park charges £6 per car when booked online; free parking is available at Killykeeghan Nature Reserve.
- Public transport: Bus services run to Belcoo and Derrygonnelly; from there a local taxi can reach the trailhead. Check the latest timetables before you travel.
- Facilities: Picnic tables and a visitor information board are at the car park. No toilets on the summit – the nearest facilities are in Belcoo.
What to See & Do
- Cuilcagh Boardwalk Trail – the “Stairway to Heaven” (6 km / 4 mi round‑trip). After a wide gravel farm track the route climbs onto a wooden boardwalk that protects the delicate blanket bog, then ascends a steep staircase to a viewing platform perched on the edge of the plateau. From here you can sweep your gaze across Lower and Upper Lough MacNean, the drumlin countryside of Cavan, and on clear days the distant Atlantic horizon and the hills of Donegal, Leitrim and Sligo.
- Ancient cairn – The Bronze‑Age burial mound at the summit offers a tangible link to the mountain’s prehistoric past.
- Geological features – Limestone pastures such as the “Fertile Rock”, swallow‑holes like Cats Hole and Pollawaddy, and exposed Glencar and Dartry limestone illustrate the karst landscape that feeds the underground Shannon Pot system.
- Wildlife – The blanket bog supports a rich assemblage of upland insects and rare birds, including red grouse, golden plover, merlin and, in summer, the occasional hen harrier. Specialized peat‑land plants such as sundews and bog rosemary add to the botanical interest.
Wildlife Highlights
The bog’s low‑nutrient environment favours species that are scarce elsewhere in Ireland. Bird‑watchers often spot:
- Red grouse – a resident of heather‑dominated bogs.
- Golden plover – migratory, best seen in spring and autumn.
- Merlin – a small falcon that hunts over the open moorland.
- Hen harrier – a rarer visitor, usually during the breeding season.
Nearby Attractions
- Marble Arch Caves Global Geopark Visitor Centre – a short drive away, offering guided cave tours and interactive displays about the karst landscape.
- Benbradagh – a rugged hill in County Londonderry with panoramic views of the Sperrin Mountains; a good option for a longer hill‑walking day.
- Lough MacNean – the twin lakes at the foot of Cuilcagh provide opportunities for fishing, kayaking and scenic walks.
Practical Information
- Trail difficulty: The boardwalk is well‑maintained and suitable for most walkers; the final staircase is steep and can be slippery when wet. Proper walking boots and waterproof clothing are recommended.
- Accessibility: No wheelchair access on the boardwalk due to steep stairs. Dogs are not permitted on the bog to protect the habitat.
- Best time to visit: Late spring to early autumn offers the clearest views and the most active wildlife. Winter walks are possible but the boardwalk can be icy, and visibility of the Atlantic horizon may be reduced.
- Safety tips: Weather on the plateau changes rapidly; carry a wind‑proof layer, map, and let someone know your intended return time. Stay on the boardwalk to avoid damaging the fragile peat.

Cuilcagh’s blend of dramatic scenery, ancient history and unique ecology makes it a standout destination for anyone exploring Ireland’s north‑west frontier.
