H1227 : Cuilcagh Mountain

Rossographer Photo source

Overview

Cuilcagh (666m) straddles County Cavan in the Republic of Ireland and County Fermanagh in Northern Ireland. Its sandstone-capped plateau rises above blanket bog. The Boardwalk/Legnabrocky Trail ends at a viewing platform, short of the true summit; follow the Geopark's current access advice.

Cuilcagh [Binn Chuilceach]

Cuilcagh is a 666m mountain on the border between County Cavan in the Republic of Ireland and County Fermanagh in Northern Ireland. It is the highest mountain in both counties. The true summit has a trig pillar on an ancient stone cairn.

Boardwalk and summit access

The Cuilcagh Boardwalk and Legnabrocky Trail are names for the same approach. From the signed boardwalk car park on Marlbank Road, follow the gravel track, wooden boardwalk and steep steps to the viewing platform. Return along the same route to the car park. This outing does not reach the summit cairn.

The Geopark currently asks visitors to remain on designated trails and within the viewing platform, and does not recommend continuing from it to the summit. Check current advice before visiting. No alternative summit itinerary is verified here.

Terrain and safety

The boardwalk route is graded Difficult. Expect steep steps, mountain exposure and potentially slippery surfaces. Weather can deteriorate in any season and mobile reception is unreliable. Bring suitable footwear, waterproofs, warm layers, food, water and navigation equipment. Protect the fragile bog by keeping to the trail.

Geology and heritage

Carboniferous sandstone and shale overlie limestone on the lower slopes. Resistant Lackagh Sandstone forms the summit edge; caves and swallow holes belong to the lower limestone landscape. Cuilcagh Mountain Park was founded in 1998 for peatland conservation.

The Irish name Binn Chuilceach is often rendered 'chalky peak', although its derivation is debated.

Access and facilities

The private boardwalk car park has limited capacity; check its booking arrangements. Killykeeghan Nature Reserve provides alternative parking and toilets, subject to opening hours. Marble Arch Caves parking is for cave visitors, not boardwalk walkers.

Dogs are not permitted on the boardwalk. Organised groups exceeding 20 people need prior written consent from Marble Arch Caves. Seasonal buses have served the nearby caves; check current services and return arrangements.

Blacklion and Belcoo serve the northern approach. Nearby hills include Benaughlin (370m) and Slieve Rushen (404m).
