There are long-distance trails and then there is the Waterford Greenway. Stretching 46 km from Waterford City to Dungarvan along the route of the old Waterford–Dungarvan railway line, it is consistently ranked as one of the finest off-road cycling and walking trails in all of Ireland — and once you’ve done it, you understand exactly why.
The Route
The trail begins at Waterford city quays and winds westward through the Suir Valley, past the market town of Kilmacthomas, through a 400-metre tunnel at Kilmacthomas, across the spectacular Durrow and Ballyvoile viaducts, and down to the coast at Dungarvan Bay. Along the way it crosses eleven railway viaducts and two tunnels — engineering feats that were extraordinary when they were built in the 1870s and are spectacular to experience from the saddle of a bike today.
The surface is tarmac for the most part, with a compacted gravel section near Waterford city. It’s almost entirely flat, making it accessible to families with young children, older cyclists and anyone who hasn’t been on a bike in a while. You don’t need to be fit. You don’t need expensive equipment. You just need to show up.
Highlights Along the Way
The Kilmacthomas Viaduct is the most photographed structure on the route — a graceful 10-arch stone bridge that carries the trail 22 metres above the Mahon River. Kilmacthomas town itself has good coffee and is a popular turnaround point for a half-day trip. The Durrow Viaduct near the coast offers views down to the sea that stop most cyclists dead in their tracks. And the arrival into Dungarvan — sweeping down toward the bay with the Comeragh Mountains behind you — is a genuinely triumphant feeling even if you’ve only come 10 km from the nearest bike hire.
Practical Information
Bike hire is available in Waterford City, Kilmacthomas and Dungarvan — many operators offer one-way hire with return shuttle, which makes the logistics simple. Allow a full day for the complete route at a relaxed pace; most people take five to seven hours. The trail is open year-round and free of charge. Dogs on leads are welcome. There are toilets and refreshment stops at Kilmacthomas, Dunhill and Dungarvan. Pack waterproofs regardless of the forecast — this is Ireland.
The Greenway is at its best in May and September when the crowds thin out and the light is extraordinary. July and August are busiest; book bike hire well in advance if you’re travelling in summer.

Frequently Asked Questions
How long is the Waterford Greenway?
The Waterford Greenway is 46 kilometres long, running from Waterford City to Dungarvan along a disused Victorian railway line. The trail is entirely off-road and almost completely flat, passing through eleven railway viaducts and two tunnels. You do not need to complete the full route — most visitors choose a shorter section between one of the towns or villages along the way.
How long does it take to cycle the full Waterford Greenway?
Cycling the full 46 km at a relaxed pace takes approximately three to four hours without stops. With stops for scenery, food and the viaducts, allow five to six hours for the full route. Most cyclists complete it as a one-way trip, using an operator’s shuttle service to return to their starting point. Walking the full route is a two-day undertaking.
Where can I hire a bike on the Waterford Greenway?
Bike hire is available at multiple points along the route including Waterford City, Kilmacthomas and Dungarvan. Most operators offer one-way hire with a return shuttle, so you can cycle the trail from end to end without retracing your route. Book in advance during July and August when hire stock fills quickly.
Is the Waterford Greenway suitable for children and beginners?
Yes. The Waterford Greenway is one of the most accessible long-distance trails in Ireland. The surface is tarmac for most of its length, the gradient is minimal throughout, and there is no road traffic. Families with young children on tag-alongs regularly complete sections of the route. Beginners should start with the Kilmacthomas to Dungarvan section (approximately 18 km) which includes the most dramatic scenery.
Are dogs allowed on the Waterford Greenway?
Yes, dogs are welcome on the Waterford Greenway but must be kept on a lead throughout. The trail passes through farmland and nature areas where livestock may be present. Be mindful of other users — cyclists, families with children and walkers all share the path and the surface can be busy at peak times.
