Overview
The Comeragh Mountains (Irish: Na Coiméaraigh) form a glaciated mountain range in the south‑east of Ireland, straddling County Waterford and the western edge of County Tipperary. Twelve distinct peaks rise to a maximum height of 792 m (2,598 ft) at Fauscoum, providing sweeping Atlantic vistas, deep valleys and a landscape shaped by the last Ice Age. The range lies just off the N25, a short drive from the historic port town of Dungarvan, and extends inland toward Clonmel. Villages such as Kilrossanty, Kilmacthomas, Lemybrien and Rathgormack punctuate the foothills, offering convenient bases for walkers and cyclists.
History & Background
The mountains owe their dramatic topography to glacial erosion, which carved a series of corrie lakes (or “coums”) and steep‑sided valleys. Coumshingaun, often described as one of the finest examples of a corrie in Europe, showcases a classic bowl‑shaped basin surrounded by sheer cliffs that rise over 365 m above the lake. Historical anecdotes add colour: in the early 20th century, WWI veteran Jim Fitzgerald – the “Hermit of Lackendara” – lived in a cave on the edge of Coumshingaun, and the lake has since been used for cold‑water swimming training.
The area has long attracted mountaineers; the Comeragh Mountaineering Club organises climbs and maintains routes, while the annual Comeragh Mountains Walking Festival in October celebrates the Nire Valley with guided walks, runs and cultural events.

Mahon Falls
One of the most photographed sites in the Comeraghs, Mahon Falls drops 80 m over sandstone cliffs near Lemybrien. A short, family‑friendly walk from a dedicated car park leads to a viewing platform where the water thunders into deep pools. After heavy rain the cascade is at its most powerful, making for dramatic photographs. Practical information: the car park is free, and a well‑marked path leads to the falls in about 15 minutes. For more details see the official page on Discover Ireland.
Coumshingaun Loop
The loop starts at Kilclooney Bridge (grid reference 348115) on the R676. After crossing a gate and a small stream, the trail ascends through mixed woodland before opening onto the corrie basin. The lake’s surface reflects the surrounding cliffs, which are home to a variety of birdlife, including red grouse, hen harrier and occasional white‑tailed eagles. The route includes a short scramble to the cairn marking the highest point of the range (Fauscoum). The walk is popular with both hikers and climbers; winter brings opportunities for ice climbing on the north‑facing cliffs.
Nire Valley Loop
Encircling the Nire Valley, this 18‑km circuit showcases the gentle river landscape, historic stone walls and the dramatic backdrop of the Comeragh peaks. The walk is dog‑free to protect livestock and sensitive wildlife habitats. Along the way you’ll pass the Nire Valley Pottery, the historic Nire Valley Pub, and several small lakes that are ideal for a quiet break.
The Magic Road
A quirky roadside attraction near Mahon Falls, the “Magic Road” appears to make a car roll uphill in reverse without any engine power. The phenomenon is a popular stop for photographers and curious travellers. The road also offers several pull‑outs with panoramic views over the Mahon and Tay valleys.
Outdoor Activities Beyond Walking
- Rock climbing – The sheer faces around Coumshingaun and the Carraig an Fhiolair route provide sport and trad climbs ranging from Diff. 5 to 7.
- Ice climbing – In winter, frozen waterfalls and north‑facing cliffs attract experienced ice climbers.
- Birdwatching – The moorland and woodland support red grouse, wheatear, siskin, crossbill and, on rare occasions, white‑tailed eagles.
- Cycling – The Waterford Greenway (46 km) links Dungarvan to the Comeragh foothills, offering a traffic‑free ride with frequent rest stops at Kilmacthomas and Kilmeaden.
- Guided tours – Local operators such as Dungarvan Tourism and Muddy Boots provide guided walks ranging from easy valley strolls to full‑day mountain treks.
Practical Information
Getting there – The range is most easily accessed from Dungarvan (via the N25) or from the R676 at Lemybrien. Parking is available at the Mahon Falls car park, at Kilclooney Bridge (for the Coumshingaun Loop) and at several lay‑bys along the Comeragh Drive. The Dungarvan Tourist Information Office (Main Street, Parnell Street, Dungarvan) can provide detailed maps; the OS Discovery Series Map 75 covers the area in depth.
Access rules – Dogs are not permitted on upland walks such as the Nire Valley Loop to protect livestock and wildlife. Visitors are asked to stay on marked paths, avoid damaging fences and walls, and take all litter with them.
Facilities – Picnic areas are provided at the base of Mahon Falls and near the Coumshingaun car park. Public toilets are available at the Mahon Falls visitor area and in Dungarvan town centre. No admission fee is charged for the walks or the falls; parking is free at the designated sites.
Seasonal considerations – The higher corries can be snow‑covered in winter, making some sections icy and suitable only for experienced walkers or climbers. Spring and early summer bring lush green valleys and the best chance to see the waterfalls at full flow.
Contact – For up‑to‑date information, route maps and any temporary closures, contact the Dungarvan Tourist Information Office at +353 (58) 41741 or email via the Dungarvan Tourism website.
Accommodation – Options range from glamping pods at Comeragh Pods to B&Bs in nearby villages such as Kilrossanty and Ballymacarbry. For a more luxurious stay, Waterford city offers hotels like the Granville Hotel, while the Waterford Greenway provides easy access to both the mountains and the coast.
Events – The annual Comeragh Mountains Walking Festival in October showcases guided walks, local food stalls and cultural performances, making it an ideal time to experience the range’s hospitality and natural beauty.
Whether you are seeking a gentle waterfall stroll, a challenging corrie loop, or simply a scenic drive through rolling Irish hills, the Comeragh Mountains deliver a memorable outdoor experience steeped in geological wonder and local folklore.
