The traffic-free Dublin walk that follows an 18th-century canal all the way to the countryside

Sharing is caring!

Dublin’s most loved walks tend to involve the coast or the parks. But the Royal Canal towpath — a traffic-free greenway that runs from the heart of the Docklands all the way to County Kildare — is something Dubliners have quietly treasured for years. This is the walk that gets you out of the city without catching a bus, train, or cab. It’s calmer than the quays, greener than the streets, and almost entirely free of other tourists.

A canal built out of spite

The Royal Canal was dug between 1790 and 1817, and it owes its existence largely to a dispute. A director of the Grand Canal Company fell out with his colleagues and left to establish a rival waterway running further north across the country. The result: two parallel canals threading across Ireland, both eventually reaching the River Shannon, more than 140 kilometres inland. For most of the 20th century, the Royal Canal fell into neglect — commercial traffic ended, locks silted up, and the towpath disappeared under weeds. Then a restoration project began in the 1990s, and today the entire route is walkable again.

Where to begin: Spencer Dock

The Dublin stretch begins at Spencer Dock in the Docklands, a short walk from the 3Arena. From here, the towpath heads west through North Strand and Drumcondra, passing beneath low stone bridges and into Phibsborough. It’s signposted throughout, largely paved on the city section, and wide enough for walkers and cyclists side by side.

The pace here is different to the city streets. People are walking dogs, pushing buggies, cycling slowly. Occasionally a narrowboat is moored against the bank, curtains drawn, smoke rising from a small chimney. The canal has its own unhurried rhythm, and it pulls you into it.

Broombridge: where mathematics met the canal

One of the walk’s unexpected highlights is Broombridge. In 1843, the mathematician William Rowan Hamilton was walking along this very canal bank when the formula for quaternions came to him — a mathematical system that underpins modern computing and robotics. He carved the equation into the bridge stonework on the spot. A plaque marks the place today. James Joyce later referenced Broombridge in Ulysses, and the bridge now has a DART station, making it a natural start or end point for a shorter section of the walk.

Lock-keeper’s cottages and canal wildlife

The Royal Canal passes through 46 locks on its full journey. The Dublin section includes several well-preserved examples, with Waterways Ireland staff still managing them in summer. The lock-keeper’s cottages — small, whitewashed, with trim gardens — stand at regular intervals along the bank. Many are still occupied. Grey herons patrol the shallows without moving for what feels like hours. Coots and moorhens nest in the reeds close to the path. On a quiet weekday morning, it can feel genuinely rural, despite being barely 3 kilometres from the city centre.

The best half-day walk: Spencer Dock to Ashtown

The 7-kilometre section from Spencer Dock to Ashtown is the most popular Dublin stretch — about two hours at a relaxed pace. At Ashtown, you can walk straight into Phoenix Park through the western gate. The herd of 600 fallow deer is often visible near the path, particularly in the early morning. From Ashtown, buses and the DART offer an easy route back into town.

The northside Dublin that tourists rarely see

Unlike the Grand Canal to the south — which passes through the polished Georgian terraces of Portobello and Ranelagh — the Royal Canal runs through working northside neighbourhoods: Phibsborough, Cabra, the Glasnevin fringes. These are parts of Dublin that haven’t been glossed up for visitors. Community allotments back onto the towpath. Old pubs like The Cat and Cage in Drumcondra serve a lunchtime crowd of regulars who’ve been coming for decades. It feels like the Dublin that Dubliners actually live in.

Wildflower meadows have been planted along sections of the bank in recent years — a project by local community groups that has brought colour and pollinators to what was once an industrial corridor. In May and June, the towpath edges bloom with oxeye daisies, meadow cranesbill, and red campion.

Practical tips before you set off

The full Royal Canal Greenway runs from Spencer Dock to Clondra in County Longford — around 130 kilometres in total. The Dublin section to Maynooth (about 25 kilometres) is the most accessible, with DART and suburban rail stations at Broombridge, Drumcondra, and further along the line.

The towpath is well-maintained but can be muddy after heavy rain on the less urban sections. Trainers are fine for the city stretch; proper walking shoes are better once you head beyond Blanchardstown. Bring water — there are few shops along the way once you leave the city.

The walk is completely free, open year-round, and has no formal opening hours. Spring and early summer are the best seasons: the light is soft, the wildflowers are out, and the canal carries a particular stillness in the early morning.

Frequently asked questions

How long is the Royal Canal walk in Dublin?

The most popular section — Spencer Dock to Ashtown — is roughly 7 kilometres and takes about two hours at a comfortable pace. Those wanting a longer outing can continue to Blanchardstown (about 14 kilometres) or all the way to Maynooth (approximately 25 kilometres).

Where is the best starting point for the Royal Canal walk?

Spencer Dock in the Docklands is the most convenient start, with easy access from the city centre by foot, DART, or Luas. If you’d prefer to skip the early urban stretch, Broombridge Station on the DART is a good alternative starting point.

Is the Royal Canal walk free?

Yes, completely. The entire greenway is publicly accessible, with no admission fee, no booking required, and no formal opening hours. It’s one of the best free things you can do in Dublin.

Can I cycle the Royal Canal towpath?

Yes. The greenway is shared by walkers and cyclists throughout its length. The Dublin city section is paved and smooth, making it perfectly suited to a relaxed cycle. Hire bikes are available through Dublin cycling tours if you’d prefer a guided outing.

The Royal Canal walk won’t feature on many bucket lists. It has no dramatic clifftop view, no famous monument at its peak. What it has is something rarer: the feeling of a city slowing down, of water doing what water has always done in Dublin — taking you somewhere, quietly, if you’re willing to follow.
