Lough Mohra Loop – A Scenic Mountain Walk in Waterford

Overview

Lough Mohra Loop is the longer of two marked circuits threading through Glenpatrick Woods, a mixed-forest and upland area just outside Rathgormack in County Waterford. The 7 km (4.3 mi) route climbs 460 m (1,510 ft) to a glacially-carved hollow known as a coum, where the still waters of Lough Mohra sit beneath the jagged Knockanaffrin Ridge. Graded as moderate, the walk typically takes around two and a half hours to complete. It is a straightforward, well-maintained day trip that suits families, casual hikers, and anyone looking to experience the rugged interior of the southeast without venturing into remote wilderness.

The Route & What to See

The walk begins on a forestry track that quickly transitions into open upland terrain. After a steady ascent, the trail drops into the marshy basin where the lake rests. On calm days, the water acts as a near-perfect mirror, reflecting the surrounding peaks and creating a striking photographic backdrop. As you follow the ridge line, the landscape opens up to reveal sweeping vistas across the region. Look east to spot the distinctive pyramidal shape of Slievenamon and the historic Kilcash estate on its lower slopes. Further along, the rolling ridges of the Walsh Mountains stretch toward the Kilkenny border.

The route passes notable geological features, including the distinctive Crotty’s Rock formation (locally known as the “Ass’s Ears”) and offers clear sightlines to Croughaun Hill. The transition from mixed woodland – dominated by oak, ash, and birch – to open mountain heath is gradual, supporting a variety of upland birds and seasonal wildflowers. Late spring and early summer bring the heather and grasses into full colour, while autumn fogs often roll into the coum, softening the landscape.

Landscape & Local History

The terrain around Lough Mohra was shaped during the last Ice Age. Retreating glaciers gouged out the shallow basin that now holds the lake, known in Irish as Loch Mór. While the loop itself focuses on natural scenery, the wider Rathgormack area carries quiet traces of early settlement. Ancient ring forts dot the surrounding hills, including An Rath Beag, Waterford’s smallest recorded fort. The shorter Rath Beag Loop diverges briefly to pass it, and walkers on the main circuit can catch glimpses of the stone enclosure on the return leg.

The Glenpatrick Woods area is actively maintained by the Rathgormack North Waterford Community Development CLG, a local group responsible for clearing the path, maintaining waymarks, and preserving the balance between visitor access and ecological conservation.

Practical Information

There are no built facilities, toilets, or refreshment stops along the route. The trailhead car park accommodates a modest number of vehicles, so arriving early on weekends helps secure a spot. Pack out all litter and keep dogs on a lead to protect nesting birds and livestock in adjacent fields.

Getting There & Navigation

From Rathgormack, head towards Clonmel on the R678. After roughly 5 km, the road turns left; shortly after, a four-way junction appears. Turn left onto the forestry track and follow it for about 500 m. The trailhead sits at the entrance to Glenpatrick Woods, marked by a small car park.

The loop is fully waymarked with red arrows. If you prefer a shorter walk, follow the blue arrows from the start for the Rath Beag circuit. Key junctions are clearly signposted, and the route returns to the same parking area, making navigation straightforward even in changing conditions. For those without a car, the nearest bus stop is in Rathgormack on the Waterford–Clonmel route (Bus Éireann 354). From there, a short taxi ride or a 20-minute walk along the R678 reaches the trailhead.

Nearby Walks

If you have time for a second hike, the Comeragh Mountains lie just to the north, offering a network of ridges, waterfalls, and longer mountain routes. For another well-marked circuit with similar glacial scenery, the Coumduala Loop in the same range provides a complementary challenge.

Start early to beat the midday crowds and allow plenty of time for the steady climb. The lake looks best when the wind drops, so check the forecast before heading out.
