Overview
Perched at 344 m (1,119 ft) above sea level, Lough‑an‑Leagh dominates the east‑Cavan landscape between Bailieborough and Kingscourt. The ridge stretches roughly five kilometres long and one kilometre wide, providing an area of outstanding natural beauty that rewards visitors with sweeping panoramas of up to fourteen surrounding counties on a clear day. The name derives from the Irish Lough‑an‑Leighis – “Lake of the Cures” – a reminder of a now‑vanished lake that once sat atop the mountain and was famed for its healing properties.
The site is managed by the volunteer‑run Lough‑an‑Leagh & Muff Heritage Trust, whose mission is to protect the area’s archaeology, ecology and visual impact while promoting its rich cultural legacy.
History
Lough‑an‑Leagh’s story stretches back to the 3rd century BC when the Gaelinga people inhabited the ridge, then known as Sliabh Gaileng – “The Mountains of the Gailenga”. Three stone‑age cairns dot the summit, each registered with Dúchas and listed on the National Monuments Register. The main cairn, Moyer Cairn, marks the highest point; a concrete triangulation pillar from the Ordnance Survey sits at its centre and offers a 360° outlook. A second cairn, Corraweelis Cairn, lies to the south‑south‑west and is largely covered in heather. The third cairn, Mohercrom, is obscured by forest on the western side of the ridge and can be difficult to locate.
Later centuries saw the mountain become a strategic watershed between the Blackwater/Annalee catchments and the farmlands of County Meath. Two rivers – the Blackwater (Bo Guaire) and the Borora (Bo Rua) – spring from the ridge and flow into the Boyne system, feeding the only “High‑Status” river water body in the Boyne catchment (Kells Blackwater).
Cultural traditions persist: Bilberry Sunday, a remnant of the ancient Lughnasa festival, still draws locals to pick bilberries on the last Sunday of July. The historic Fair of Muff, dating from 1608, is held each 12 August and continues to attract horse traders and visitors from across the region. In the 19th century an old coach road – the “Bridle Path” – crossed the ridge, and races were run here in preparation for the Fair.
The once‑filled lake at the summit was reputed to have curative mud; visitors with skin ailments would apply the mineral‑rich mud, and a Dublin merchant even bottled the water in the 1800s, selling it for two shillings a gallon. The lake eventually dried up, leaving only the name as a reminder of its former healing fame.
Legends & Folklore
Local lore tells that a Cailleach (divine hag) dropped stones from her apron, forming the three cairns that mark the ridge. Another tale speaks of a priest who, during Penal Times, threw the Mass chalice into the lake to hide it from soldiers; the chalice’s reputed healing powers were then said to reside in the waters. A magical hare is also associated with the hill, said to appear at dusk and guide wanderers.
Flora, Fauna & Wildlife
The heather‑covered slopes burst into purple in late summer, while bilberry bushes provide a seasonal bounty for foragers. Birdwatchers can spot skylarks, sparrowhawks, kestrels, goldcrests and peregrine falcons soaring over the ridge. Small mammals such as field mice and hares are common, and the “magical hare” legend adds a whimsical touch for visitors.
Mass Rock & Easter Dawn Mass
A historic Mass Rock sits near the summit, marked on the trailhead. It continues to be used for a Dawn Mass each Easter Sunday, offering a moving experience against the backdrop of the sunrise and the expansive landscape.

Walking Trails
The Trust maintains five way‑marked, Sports Ireland‑approved trails ranging from easy loops to moderate ridge walks. The most popular route – often listed as the “Lough‑an‑Leagh Walk” – is a 4.8 km loop (approximately 1 hour 30 minutes) graded moderate. The terrain combines mountain paths, forest tracks and a few stony sections, so sturdy shoes are advisable. Highlights along the route include:
- Heathland & Heather – vibrant purple heather supports a variety of insects and birds.
- Panoramic Viewpoints – after the fork, a right‑hand turn leads to a bench with vistas across 13 counties and, on exceptionally clear days, the Irish Sea.
- Cairn Exploration – the three protected cairns can be examined up close; the Corraweelis cairn bears a protection notice after past damage.
- Birdwatching – early mornings are ideal for spotting raptors and songbirds.
For families, the loop is child‑friendly and offers plenty of rest spots. The route is also car‑free for 67 % of its length, providing a peaceful walking experience.
