Overview
The Owencarrow River is the principal outflow from the shimmering Lough Veagh, coursing through the heart of Glenveagh National Park in County Donegal. Though only a few kilometres long, the river packs a punch of natural drama: clear, fast‑moving water that supports a surprisingly diverse aquatic community, and a recently built bridge that has become a focal point for walkers, runners and anglers alike. Whether you are tracing the river’s path on the Glenveagh Lakeside Walk or casting a barbless fly in its deeper pools, the Owencarrow offers a slice of Irish wilderness that feels both intimate and grand.
History & Heritage
Owencarrow Viaduct
The river is spanned by the historic Owencarrow Viaduct, a 400‑metre railway bridge constructed in 1903 as part of the narrow‑gauge Burtonport extension of the Londonderry & Lough Swilly Railway. Built with granite blocks, oak piles and even sheep’s fleeces driven into the bog, the viaduct was an engineering marvel of its time, assembled entirely by hand and horse‑power. A temporary steam‑driven pile driver was used to push oak trunks into the bottomless bog, and dynamite blasted the massive cuttings that form the valley today.
1908 Derailment
A lesser‑known incident occurred in 1908 when a train derailed on the viaduct. No lives were lost, but the event highlighted the challenges of operating on the exposed, wind‑swept valley.
1925 Disaster
On the night of 30 January 1925, a fierce storm with gusts up to 125 mph caused a passenger railcar to overturn on the viaduct. Four people lost their lives and many were injured. The tragedy was one of the worst rail disasters in Irish history and left a lasting imprint on the local community.
Centenary Commemoration (2025)
In January 2025 the community marked the 100th anniversary of the disaster. A newly cleared viewing area and memorial were unveiled near the viaduct, with a free shuttle service from the car‑park behind St Michael’s Church in Creeslough. The event featured speeches from the Owencarrow Viaduct Committee, a moment of silence and a family‑run refreshment stall in the Creeslough community hub. Volunteers, led by local volunteers Michael Doyle and the late Ben McFadden, cleared a pathway to bring visitors closer to the structure.
Sustainable Bridge
As part of the Glenveagh Lakeside Walk, park staff installed a new footbridge over the Owencarrow River in 2021. The structure uses seasoned larch timber for the deck supports and a surface made from recycled‑plastic decking, creating a low‑maintenance, environmentally friendly viewpoint. Runners and walkers appreciate the bridge for its solid footing and the panoramic outlook it provides over the fast‑flowing water and surrounding blanket‑bog habitat.
What to See & Do
Walking the Lakeside Trail
The most popular way to experience the Owencarrow is as part of the Glenveagh Lakeside Walk. This 3.5 km linear route (approximately 7 km return) starts at the bus shelter near the Glenveagh Visitor Centre (grid reference C 039231). The path is a mostly flat gravel track that winds through mature Austrian pine stands, native broad‑leaved trees such as holly, rowan and birch, and skirts the shores of Lough Veagh. Mid‑way, walkers cross the Owencarrow on the new sustainable bridge, offering a perfect viewpoint of the river’s clear flow and the surrounding bogland.
Beyond the bridge, the trail opens onto expansive blanket bog and wet heath, habitats that, while seemingly barren, host a wealth of specialised plants and insects. The walk culminates in the meticulously maintained gardens of Glenveagh Castle, a striking contrast to the wildness that precedes it.
Viewing the Viaduct
A short, well‑signposted path leads from the main Lakeside Walk to the historic viaduct. Visitors can park in the lay‑by created by the voluntary Owencarrow Viaduct Committee (off the L1332 near the Drimnaraw crossroads) or use the free shuttle that runs from St Michael’s Church on event days. A modest interpretive panel explains the construction techniques and the 1925 tragedy. The memorial consists of a stone plaque and a seating area that offers panoramic views of the river valley.
Fishing the River
For those with a licence, the Owencarrow presents a rewarding fly‑fishing experience. The river stretches about four miles from Lough Beagh to Glen Lough, with deep, slow‑moving sections that respond well to a stiff breeze and a well‑presented drawn fly. The fishery is managed by Inland Fisheries Ireland (IFI) Ballyshannon and operates under a catch‑and‑release regime for salmon and sea trout over 40 cm during the 2025 season (12 May – 30 September). Anglers must use single or double barbless hooks, and bait or worm fishing is prohibited.
A day permit costs €30 for adults and €17 for juveniles. The fishery rules limit sea trout under 40 cm to three per day and require anglers to fish one rod at a time, maintaining a respectful distance from fellow anglers. Permits, licences, logbooks and tags must be presented before entering the fishery. Should you witness illegal activity, IFI can be contacted on 071 985 1435 (24‑hour line: 0818 347424).
Wildlife Watching & Conservation
The clear waters of the Owencarrow are a haven for breeding salmon, trout, eel, the rare freshwater pearl mussel and playful otters. The surrounding woodlands and bogs attract a variety of birdlife, including meadow pipits, skylarks and occasional golden plovers. Early‑morning strolls are ideal for spotting these species. Conservation work, coordinated by IFI and local volunteers, focuses on protecting the pearl‑mussel habitat and maintaining the health of the blanket‑bog ecosystem.
River’s Course Beyond Glenveagh
After leaving Glenveagh National Park, the Owencarrow continues south‑west, eventually joining the sea at the historic Lackagh Bridge near Doe Castle. This downstream stretch offers additional scenic spots for anglers and walkers.
Events & Community Activities
Owencarrow River Run
Since 2022 a local running club has organised the Owencarrow River Run, a 5 km trail race that follows the Lakeside Walk and finishes at the new sustainable bridge. The event attracts both competitive runners and families, providing a lively way to experience the river’s scenery. Registration details are posted on the Creeslough Community Association website each spring.
2025 Centenary Commemoration (see History section)
The centenary event demonstrated the strong community spirit surrounding the viaduct, with a free shuttle from St Michael’s Church, a newly cleared viewing platform and a memorial ceremony.
Community Involvement & Volunteering
The voluntary Owencarrow Viaduct Committee, working with the Creeslough Community Association, has overseen recent improvements:
- Creation of a lay‑by and parking area at the L1332 junction.
- Clearing of a new viewing platform close to the viaduct, funded in part by local landowner Joe Sweeney.
- Organisation of the free shuttle service for the 2025 centenary (operating every 15 minutes from 11:15 am).
- Ongoing maintenance of interpretive signage and the memorial plaque.
These efforts have turned the site into a well‑visited heritage spot, drawing locals and tourists alike.
Recent Improvements to Angling Access
In June 2019 Minister Sean Canney officially opened a new angling facility funded by Inland Fisheries Ireland and the Creeslough & District Angling Association. The project improved riverbank access, installed safe entry points and added signage along the Owencarrow, Glen Lough and Lough na Tooey, supporting sustainable tourism in North Donegal.
