Barrow Way Walking Holiday — 6 Days (Moderate)
Athy to St. Mullins — four flat, unhurried days following the Barrow downstream
6 Days on the Barrow — Athy to St. Mullins, the Whole Lower River
Six days is the sensible Barrow trip. Four walking days, two travel days, and the entire lower half of the river to walk down at your own pace. You start in Athy — a 13th-century Anglo-Norman heritage town where the Grand Canal meets the Barrow — and finish at St. Mullins where the river meets the tide.
From Athy you walk south to Carlow, then on to Bagenalstown, then Borris, and finally to St. Mullins itself. The towpath is flat the whole way, the distances are evenly paced (16–20 km a day), and the four villages you sleep in are some of the prettiest in the South-East. You'll know the rhythm of the river by the second morning.
What this trip gives you that the 5-day doesn't is the Athy-to-Carlow section — a beautiful, slow opening where the canal towpath gives way to the riverbank and the character of the walk really shifts. You pass old mills, lifting bridges, lock-keeper's cottages with washing on the line, and arrive on foot into Carlow town the way travellers have for centuries — riverside, unhurried, by the back door rather than the motorway.
The middle section, Carlow to Borris, is the heart of it: woodland-flanked towpath, working locks at Clashganny, the elegant three-bridge crossing at Milford, the quiet Georgian streets of Bagenalstown. And the finish at St. Mullins — where you stand in a churchyard that's been in continuous use since the 600s — is one of those Irish moments that genuinely stays with you.
This is a walking holiday for people who want depth, not just box-ticking. Same long-distance trail, same flat ground, but with the breathing room to enjoy each town properly. I've been sending guests down this river for years, and the feedback I get from the 6-day more than any other is that it felt like their trip — not a package. By the end of six days here, you'll feel like the Barrow is partly yours.
Highlights
The Whole Lower Barrow
Athy in the morning, St. Mullins on the fourth walking day. Four full days of riverside walking through every town that matters on the lower river — no rushing, no skipping the best parts.
Heritage Town Starts and Finishes
Begin in 13th-century Athy with its Norman castle and Dominican church. End in 7th-century St. Mullins with its monastic ruins and round tower stump. A thousand years of Irish history under your feet.
Four Genuine Country Villages
Athy, Carlow, Bagenalstown, Borris — each with its own pub, bakery, character. We''ve picked the B&Bs personally and dinner is always within five minutes'' walk.
Flat, Forgiving Walking
Four days at 16–20 km on a level towpath. No climbs, no scrambling, no descent damage. The route is welcoming to anyone with reasonable fitness, regardless of age.
Who Is This For?
Walkers who want a full long-distance trail experience without the longer commitment.
Six days, four walking days, the whole lower Barrow from Athy to St. Mullins. It's long enough to feel properly immersed in the river — you'll know the names of the bridges by the third day — but short enough to leave the rest of your week intact.
Couples and friends looking for a gentle, sociable walk.
The pace is forgiving and the towns along the way have good pubs, good food, and pleasantly walkable centres for the evenings. Many guests come as twos or fours; the towpath is wide enough to walk side-by-side and chat the whole way.
People who don't love climbs.
If your knees object to descents, or you're just past your hill-walking years, this is the route. Flat the whole way, predictable underfoot, and you'll finish each day with energy left in the tank.
Tour Itinerary
Day
1
Arrival in Athy
expand_more
Arrival in Athy
Make your way to Athy, where your Barrow Way holiday begins. Athy is a fine Anglo-Norman heritage town established in the 13th century to control the river crossing — its castle, Dominican church and excellent heritage centre tell that story well.
Settle in to your accommodation, take a stroll down to the riverside, and enjoy a relaxed dinner. Tomorrow you start walking.
Day
2
Athy to Carlow
expand_more
Athy to Carlow
Your first full day on the trail. Leaving Athy you join the river properly — the canal towpath gives way to the riverbank, and the character of the walk shifts. The Barrow widens and slows here, flanked by reeds and willows, the occasional fisherman''s tent on the far bank.
You''ll pass old mills and traditional lifting bridges, each a small piece of industrial history. Carlow is the largest town on the Barrow, and arriving on foot along the riverside feels like the right way to come in. Carlow Castle is remarkably intact considering its age, and the cathedral is well worth a visit before dinner.
Day
3
Carlow to Bagenalstown
expand_more
Carlow to Bagenalstown
Out of Carlow on the towpath and back into the rhythm of the river. About 7 km south of town you reach Milford — three elegant bridges over the Barrow beside the shell of an old mill, surrounded by woodland. One of the most photographed spots on the whole route, and a perfect place to stop for lunch.
The walking continues south through pastoral country to Bagenalstown — locally Muinebheag — a quiet Georgian village with good food and a warm welcome.
Day
4
Bagenalstown to Borris
expand_more
Bagenalstown to Borris
A slightly shorter day, which means time to linger. The towpath here briefly joins the Leinster Way, Ireland''s second-longest waymarked trail. Near Ballytiglea Bridge you turn off the river for the final 2 km into Borris.
Borris is a village to savour — a wide stone-built main street, the grand gates of Borris House at the far end, rolling Carlow hills rising behind. It has a quietness that feels deliberate rather than sleepy.
Day
5
Borris to St. Mullins
expand_more
Borris to St. Mullins
Your final walking day, and one of the loveliest. South of Borris the valley narrows and the wooded hillsides close in on both sides of the river — this is the section guests remember most clearly.
You finish at St. Mullins, one of Ireland''s oldest and most atmospheric ecclesiastical settlements. Founded by St Moling in the 7th century, it sits where the Barrow meets the Duiske, surrounded by monastic ruins, a round tower stump and a graveyard in continuous use for over 1,400 years. The peace here is real.
Tonight you stay just upstream in Graiguenamanagh — a handsome stone-built town where Duiske Abbey still stands complete on the main street, one of the finest Cistercian abbey churches in Ireland. A good final evening: river, abbey, a proper meal, and the satisfaction of the miles behind you.

Departure

Departure
A leisurely morning. A last full Irish breakfast. A last look at the river.
Make your way onward — Dublin Airport is around 1 hour 45 minutes by road, and Kilkenny is just 40 minutes away if you fancy adding a night in one of Ireland''s prettiest medieval cities before heading home.
Route & Map
Accommodation
Five nights in carefully chosen B&Bs and small guesthouses along the route — Athy, Carlow, Bagenalstown, Borris, and Graiguenamanagh or St. Mullins. Every room is en-suite, every breakfast is the full Irish, every host is someone we've worked with for years.
Your main luggage is transferred door-to-door each walking day, so you carry only a light daypack — water, layers, lunch, your camera. You arrive each evening to find your bag already waiting in your room.
The houses we use are family-run for the most part, several of them by people who started hosting walkers when we sent our very first guests down this trail. You'll find warm welcomes, dinner recommendations, and the kind of casual local knowledge that makes a holiday feel like more than just a hotel stay. If something isn't right, I hear about it the same day.

Best Time to Visit
May, June and September are ideal.
May offers long bright evenings, fresh wildflowers and bright green foliage.
June provides the longest daylight hours.
July and August are busiest; book three to four months ahead.
September is the finest: bracken turns gold and rust, light on the water is clear and beautiful, wildflowers remain, and accommodation books more easily.
October brings autumn colours and is very walkable.
The trail is accessible year-round, but winter sections can be muddy with shorter daylight.
Time your visit with a festival. Many trails host walking festivals throughout the season — see our complete 2026 walking festivals calendar to plan around one.
