Monavullagh Mountains

Overview

The Monavullagh Mountains sit on the southern edge of the famed Comeragh plateau in County Waterford. Though the name appears on Ordnance Survey maps, locals usually refer to the individual hills or simply call the whole area the Comeraghs. The range is a compact but rugged massif of about 15 km in length, characterised by steep coums (glacial corries), bog‑filled plateaux and a series of striking summits that overlook the Mahon Valley, Dungarvan Bay and the distant Celtic Sea.

A typical weekend walk begins at a small car park on the 400 m contour just off the R676, a short distance north of Lemybrien. From there the trail climbs through a series of “spot heights” – Coumfea (711 m), Seefin (726 m) and the false‑man peak Farbréaga (593 m) – before looping back via the dramatic Barnanmaddra Gap. The whole circuit takes roughly five hours, gains about 900 m of elevation and is best described as a hard‑grade hill‑walk.

Naming and Local Perception

The name Monavullagh (Irish Móin a’ Mhullaigh – “bogland of the summit”) has been on OS maps since the 19th century, covering the southern part of the Comeragh plateau from Milk Hill to Crohaun. Historical records such as the 1650 Down Survey, Charles Smith’s 1774 Ancient & Present State of Waterford, and Rev. Ryland’s 1874 map all use the term. However, long‑time residents rarely use Monavullagh Mountains in everyday conversation; they speak of individual hills or refer to the whole area simply as the Comeraghs. The name persists in official cartography but remains a technical label rather than a locally recognised range.

History & Background

The name Monavullagh derives from the Irish Móin a’ Mhullaigh, meaning “the bogland of the summit”. The term is recorded in the 17th‑century Down Survey and on Charles Smith’s 18th‑century maps, where the whole southern ridge is labelled “Monevullagh Mountains”.

Local folklore links the highest point, Seefin, to the legendary hero Fionn Mac Cumhaill, who is said to have rested there while pursuing Diarmuid and Gráinne. A triangulation station on Seefin bears the name “Mullach See Finn” (the hill of the fairy hill), reinforcing the mythic aura of the ridge.

Geology & Landscape

The Monavullagh range is a product of the last glaciation. Ice carved deep‑walled coums such as Coumshingaun and Coumtay, leaving sheer cliffs and classic corrie lakes. The bedrock is mainly green, thick‑bedded conglomerate of the Treanearla Formation, the same rock that underlies much of the Comeragh Mountains (see Britannica). This geology creates the dramatic “eyes of an alien” – the deep‑blue Coumfea Lakes that sit in a steep‑sided corrie.

Flora & Fauna

The upland moorland supports a mix of heather, blaeberry and bog cotton, while the crag edges host alpine‑type plants such as mountain avens. Birdlife is a highlight: red grouse, hen harrier, wheatear, siskin and crossbill are regulars, with occasional sightings of white‑tailed eagle, hobby and nightjar. Early‑morning visits in spring or autumn give the best chance of hearing the harrier’s distinctive call.

Walking Routes & Variations

Classic 15 km Loop (hard grade)

1. Start – Main car park (grid ref 313 075) on the 400 m contour.
2. Coumfea Lakes – A short 2 km spur to the lakes, ideal for photos.
3. Seefin – Ascend to the summit, explore the Bronze‑Age cairn, the concrete TV hut and the fallen trig pillar.
4. Barnanmaddra Gap – Descend into the “Stone Man” gap, view the painted standing stone.
5. Farbréaga – Climb the “False Man” peak for views over Crohaun and Helvick Head.
6. Descent – Follow the well‑marked spur back to the car park, avoiding the long plateau return.

Alternative Short Loop (10 km)

For those short on time, the route can be cut after Barnanmaddra Gap and return via the lower road track, reducing the walk to about 3 hours and 600 m ascent.

East Munster Way Connection

The long‑distance East Munster Way passes close to Mahon Falls. Ambitious walkers can link the Monavullagh loop with a section of the East Munster Way for a full‑day trek of over 20 km.

Seasonal & Weather Advice

The ridge is prone to fog and sudden cloud cover, especially in late autumn and winter. Summer offers the most reliable footing, but the boggy plateaux can become water‑logged after rain. Early spring brings vivid wildflower displays, while autumn provides spectacular golden heather. Always check the mountain‑forecast before setting out and carry waterproof clothing.

Practical Information

Access & Parking – The primary car park holds exactly 12 vehicles; a second, smaller car park half a kilometre further up the road is preferred for the Mahon Falls route. There are no known seasonal restrictions, but spaces fill quickly in the May–September peak season, so arrive early. Dogs are permitted on leash.

Route Details

Getting There – From Dungarvan take the N25 east for 12 km, then turn left at the Lemybrien fork onto the R676 towards Carrick‑on‑Suir. Follow the signposts for Mahon Falls; the upper car park is reached after passing the main falls car park and continuing another 0.5 km.

Navigation – The area is sparsely marked. An OS Discovery Series map (Sheet 75) is strongly recommended, as is a compass. The grid reference for the summit of Seefin is S274 068.

Safety Note – The ridge includes several sheer drops and loose scree, particularly around Coumtay and Barnanmaddra Gap. The route is not suitable for children or those unfamiliar with mountain navigation.
