The Lough Derg Way: Walking the Shannon from Limerick City to the Lake
Most Irish long-distance trails start in the middle of nowhere. The Lough Derg Way starts on a city quay, in Limerick, about four minutes' walk from a coffee. Within an hour you are on a canal bank with herons for company, and by the end of the third day you are standing on the shore of the biggest lake on the Shannon looking at sailing boats. It is one of the gentlest introductions to waymarked walking that Ireland has.
It is also, we have to say plainly, a trail with problems. More than half of it is on public road, and the final stretch into Dromineer has been reported as badly overgrown for several summers running. That does not mean you should skip it. It means you should know which parts to walk, and that is what this guide is for.
What the Lough Derg Way actually is
The Lough Derg Way is a National Waymarked Way of roughly 68 km running from Limerick City to Dromineer in County Tipperary, on the eastern shore of Lough Derg. Sport Ireland lists it at 68.9 km with 527 m of total ascent and grades it Moderate. It is a linear route, walked in three days by most people, and it is waymarked throughout with the standard yellow arrow on a black background.
The official start is at Arthur's Quay in Limerick, by the tourist office behind the Hunt Museum. From there the trail follows the River Shannon and its canal system north-east through Clonlara, O'Briensbridge and Killaloe, then climbs into the Arra Mountains above the lake before dropping to Garrykennedy and running north to Dromineer.
It was reconfigured and relaunched in 2011, with about €115,000 of investment under the Comhairle na Tuaithe Walks Scheme taking several sections off the road and onto private land with landowners' agreement. That work made a real difference to the middle of the route. It did not solve the road problem at either end.
The route, day by day
Day one: Limerick City to Killaloe, about 26 km
This is the best day, and if you only have one day to give the Lough Derg Way, give it this one. You leave the city along the Park Canal, pass through the University of Limerick campus with its footbridges over the Shannon, and then join the headrace canal that feeds the Ardnacrusha power station.
It is flat, it is easy underfoot, and it is far more interesting than "canal walk" makes it sound. This is engineering history you are walking through — the Errina Canal has rope grooves worn into the stonework of its bridge by generations of horse-drawn barges, and the whole Shannon navigation was reshaped in the 1920s when Ardnacrusha was built. Read half an hour about it before you go and the day doubles in value.
Two warnings. There is a stretch of fast road shortly after you leave the headrace canal at Parteen Weir where you need to walk with real care. And works on the UL campus have closed or diverted the trail there in the past, so check the current status with Sport Ireland Outdoors before you set out.
From O'Briensbridge onward it is quiet country road all the way to Killaloe, and pleasant enough.
Day two: Killaloe to Garrykennedy, about 19 km
The short day and the one with the climbing. You cross the bridge from Killaloe into Ballina in Tipperary and start up into the Arra Mountains, and this is where the route earns its Moderate grade.
The high ground around Tountinna — 457 m, the highest of the Arras — gives you the whole Shannon basin at once: Lough Derg laid out below, the Clare hills across the water, and on a clear day a genuinely huge view. Just below the summit is the Graves of the Leinstermen, a standing stone marking a burial site from around 1500 BC. Local legend ties it to a quarrel between Brian Boru's men and visiting Leinster nobles, which is a much better story than the truth, but the monument is prehistoric and predates Brian by two thousand years.
Past the viewpoint known as The Lookout the climbing is finished and the trail drops through forestry to Garrykennedy, a small stone harbour on the lake with a couple of pubs. It is a lovely place to finish a day.
Day three: Garrykennedy to Dromineer, about 23 km
This is the section to think hard about. It begins with roughly ten minutes on a busy main road with only a short stretch of footpath, then moves onto field paths across low ground near the lake — the Callows, around Youghalarra.
Walkers have reported this stretch as badly overgrown in high summer for several years now: waist-high nettles and brambles, stiles buried in growth, electric fences strung across access points, and cattle in the fields. Sport Ireland's own trail reviews carry these reports year after year. Some walkers have turned back.
Our honest advice: if you are walking between May and September, treat the last 20 km as unreliable. Walk Limerick to Garrykennedy — which is genuinely good — and arrange a lift for the rest, or walk this section in early spring or late autumn when the growth has died back.
How hard is it, really?
Physically, not very. There is one hill day and two flat ones, and 527 m of ascent spread over 68 km is modest by Irish standards. If you can walk 25 km on level ground you can walk this trail.
The difficulty is logistical rather than physical. Accommodation along the route is thin, which forces the awkward three-day split; several walkers report having to do 30 km days simply because there was nowhere to stop in between. Public transport beyond Limerick is close to non-existent. And on the road sections, traffic is a genuine hazard rather than an inconvenience.
Killaloe and Ballina are the one place on the route with a proper choice of beds and food, which is another reason the Limerick-to-Killaloe day works so well as a standalone walk.
Killaloe is worth a day of its own
If you take nothing else from this guide, take this. Killaloe is a heritage town and it deserves more than a bed for the night. St Flannan's Cathedral has an early Christian oratory and an Ogham-and-runic inscribed stone in the same building. Brian Boru, High King of Ireland, had his seat at Kincora here in the eleventh century. The lake begins immediately upstream and the town sits on the narrow neck where it drains into the Shannon.
The East Clare Way also meets the Lough Derg Way at Killaloe, so if you want to make a longer trip of it, the connections are there. For how this trail fits alongside the rest of the network, see our guide to Ireland's National Waymarked Ways.
Practical planning
Best time to walk: April to early June, or September to October. High summer is when the overgrowth on the northern section is at its worst. Winter is walkable on the canal sections but the road walking gets unpleasant in poor light.
Maps: OSI Discovery sheets 58, 59 and 65. Sport Ireland Outdoors publishes five downloadable section maps covering Limerick to Clonlara, Clonlara to O'Briensbridge, O'Briensbridge to Killaloe, Killaloe to Castletown and Castletown to Dromineer.
Navigation: waymarking is good on most of the route and poor to absent in the fields on the final section. Carry a GPS route on your phone regardless.
Dogs: not permitted. The route crosses working farmland with livestock throughout.
Getting there and back: Limerick is easy — trains and buses from Dublin, Cork and Galway, and Shannon Airport is twenty minutes away. Dromineer is not. Plan your return transport before you start walking, not after.
Who this trail suits
It suits the walker who wants water, history and easy ground rather than mountains — someone who would enjoy the engineering of the Shannon navigation as much as the view from Tountinna. It suits a day walker based in Limerick perfectly. It suits a first-time long-distance walker less well than it should, purely because of the accommodation gaps and the road.
We do not run a walking holiday on the Lough Derg Way, and the reason is the same one that makes it awkward to walk independently: there simply are not enough places to stay in the right spots to build a proper self-guided itinerary with luggage transfers.
If it is the flat, riverside, watching-the-water kind of walking that appeals to you, our Barrow Way walking holiday gives you exactly that character over five to eight days, with beds and bag transfers arranged along the whole route — we have written a full Barrow Way trail guide if you want to read about it first. If it is County Clare you want, our Burren Way walking holiday takes you through the limestone country an hour west of Killaloe. Either way, we are always happy to talk it through — get in touch and tell us what you are after.
Frequently Asked Questions
How long is the Lough Derg Way?
About 68 km from Limerick City to Dromineer, County Tipperary. Sport Ireland lists it precisely at 68.9 km with 527 m of ascent. You will see 64 km quoted in some places, which reflects an older configuration of the route.
How many days does the Lough Derg Way take?
Three days is the standard split, but the stages are uneven and accommodation is scarce, so many walkers end up doing 30 km days. Four days is more comfortable if you can find beds in the right places.
Is the Lough Derg Way difficult?
Physically it is one of the easier National Waymarked Ways — one hill day above Killaloe and two mostly flat days. Sport Ireland grades it Moderate. The real difficulties are the road walking and the sparse accommodation, not the terrain.
How much of the Lough Derg Way is on roads?
About 38 km, or roughly 55% of the route, follows local roads. Some of those are quiet country lanes and pleasant enough. A short stretch after Parteen Weir and another leaving Garrykennedy carry fast traffic and need care.
What is the best section of the Lough Derg Way to walk in a day?
Limerick City to Killaloe, about 26 km along the Park Canal, the University of Limerick campus, the Ardnacrusha headrace and the Errina Canal. It is flat, well surfaced, historically fascinating, and Killaloe is a good place to finish.
Is the Lough Derg Way well maintained?
The southern half is in good condition. The final section from Garrykennedy to Dromineer, particularly around Youghalarra and the Callows, has been reported as heavily overgrown in summer for several years, with buried stiles and electric fences across access points. Check recent trail reviews before committing to that stretch.
Can you bring a dog on the Lough Derg Way?
No. Dogs are not permitted. The route crosses working farmland with cattle throughout, and access depends on landowners' goodwill.
Does Walking Holiday Ireland offer the Lough Derg Way?
We do not. There is not enough accommodation in the right places along the route to build a self-guided walking holiday with luggage transfers. For similar riverside walking we would point you to the Barrow Way, and for County Clare to the Burren Way.
