Overview
Kilmacthomas (Irish: Cill Mhic Thómais) is a small but vibrant village on the banks of the River Mahon, midway between Waterford City and Dungarvan. Locally called “Kilmac”, it has a population of just under 1,800 and serves as a natural stopping point for cyclists, walkers and anglers travelling the 46‑km Waterford Greenway. The village’s charm lies in its blend of industrial heritage – the preserved railway viaduct and former workhouse – and spectacular natural assets such as Mahon Falls, the Comeragh foothills and the nearby Copper Coast UNESCO Global Geopark.
History
The story of Kilmacthomas is woven through centuries of Irish history. In December 1649 Oliver Cromwell’s army was forced to bivouac in the field that is now the public park after the Mahon River flooded, an episode recorded in his own diary. The village later hosted Daniel O’Connell on a 1826 campaign trail, who famously wrote about the warm reception he received over breakfast at the local inn. The arrival of the Waterford‑to‑Mallow railway in the early 1870s brought industrial growth; the stone viaduct that spans the Mahon River remains a striking reminder of that era. Although passenger services ceased in the late 1960s, the line lives on as the Waterford Greenway, opened in 2017.
What to See & Do
Waterford Greenway & Kilmacthomas Viaduct
The Greenway is a car‑free, 46‑km trail that follows the old railway corridor. At Kilmacthomas the iconic 19th‑century viaduct arches over the Mahon River, offering panoramic views of the Comeragh Mountains and the river’s gentle bends. The trail is open 24 hours a day, free of charge, and is suitable for walkers, cyclists and wheelchair users. Bike‑hire is available at the former workhouse (see Practical Information).
Mahon Falls
Just a 15‑minute drive south of the village, Mahon Falls drops 80 metres into a U‑shaped valley. A short, well‑marked 20‑minute walk from the car park brings you to the base of the cascade, where the mist‑filled air creates a dramatic backdrop for photos. The site is popular with picnickers, rock climbers and families looking for a quick nature escape.
Kilmacthomas Workhouse (Business Centre)
Originally built during the Great Famine, the workhouse now houses the Kilmacthomas Business Centre. Inside you’ll find Coach House Coffee, Waterford Greenway Bike Hire and Mayfield Birds of Prey. The adaptive reuse of the building provides a tangible link between the village’s somber past and its modern entrepreneurial spirit.
River Mahon Fishing
The Mahon River is renowned for wild brown trout, salmon (running from June onward) and sea trout in late summer. Anglers can cast from the riverbanks in the village or head to Ballyshunnock Reservoir for coarse fishing of brown and rainbow trout.
Farmers Market (Thursday)
Every Thursday from 9.30 am to 2 pm the village square transforms into a bustling market. Stalls showcase seasonal fruit and veg, organic meat, artisan cheeses, homemade cakes and jams – a perfect spot to sample local flavours and meet the producers.
Copper Coast & Bonmahon Beach
Only five miles south, the Copper Coast Geopark stretches along 25 km of dramatic cliffs, coves and sandy beaches. Bunmahon (Bonmahon) Beach offers surf‑friendly waves, while the Geopark Centre explains the area’s 460‑million‑year geological story.
Comeragh Mountains
The foothills rise just west of Kilmacthomas, providing ample opportunities for hill walks, guided hikes and mountain biking. The Cloughlowrish Stone, an Ice‑Age glacial erratic, sits along the Greenway and is steeped in local legend.
