Barrow Way

📍 Kildare, Kildare

🏛️ Attraction

Last updated: 4 June 2026

Overview

The Barrow Way is a National Waymarked Trail that stretches 117 km from Lowtown in County Kildare to St Mullins in County Carlow. Managed by Waterways Ireland, the route follows the historic towpaths of the Barrow Navigation, beginning along the Barrow Line Canal before joining the River Barrow at Athy. Graded as easy, the trail features a virtually flat profile with minimal elevation gain, making it an accessible option for casual walkers, families, and cyclists exploring the same corridor.

The path is clearly marked with a yellow arrow on a black background. Dogs are welcome provided they are kept on a lead. While the full route is typically completed over four days, most visitors break it into shorter out-and-back sections, using the numerous towns and villages along the way as convenient base camps.

Trail Sections & Highlights

The Barrow Way passes through four counties, but its character remains consistently rural and water-focused. Each stage offers distinct scenery and points of interest:

  • Lowtown to Monasterevin (23 km): The opening section follows the Grand Canal and Barrow Line Canal. Walkers get sweeping views toward the Hill of Allen and the Wicklow Mountains, with the dramatic ruins of Dúnamase Fortress standing out near Monasterevin.
  • Monasterevin to Athy (23 km): This stretch transitions to the river proper, passing historic stone bridges, well-preserved lock-keeper cottages, and quiet canal-side villages.
  • Athy to Carlow (19 km): You’ll encounter engineered landmarks like lifting bridges and old watermills before reaching the county town. Athy makes a natural halfway stop, with a train station, heritage centre, and plenty of cafes.
  • Carlow to Bagenalstown (16 km): The route crosses the famous three bridges at Milford, a favourite spot for birdwatchers, before reaching Leighlinbridge and its Black Castle.
  • Bagenalstown to Graiguenamanagh (26 km): The longest stage takes you past Goresbridge and the quiet village of Borris, finishing at Duiske Abbey, founded in 1204.
  • Graiguenamanagh to St Mullins (6 km): A short, wooded finale leads to the medieval monastic settlement at St Mullins, where a round-tower base and heritage centre mark the official trail end.

History & Heritage

The Barrow Way traces a waterway that has shaped the region for centuries. The River Barrow, Ireland’s second-longest river, was made navigable in the 18th century through a series of short canal cuts and locks. The trail’s early section follows the Barrow Line Canal, a branch of the Grand Canal engineered to connect inland waterways to the River Barrow at Athy.

Walking the towpath feels like moving through a living archive. The corridor holds evidence of Neolithic farming communities, Anglo-Norman fortifications, and medieval monastic foundations. Key heritage stops include Carlow Castle and the Cathedral of St Carthage in Carlow town, the 13th-century ruins at Dúnamase, and the abbey church at Duiske. Many of the villages retain their original street layouts and stone-fronted shops, reflecting centuries of trade and river traffic.

Wildlife & Nature

The flat, grassy towpath and slow-moving river create ideal conditions for wildlife. Spring and early summer bring the riverbanks to life with flag iris, meadowsweet, ragged robin, and purple loosestrife. The area around Milford, often called the “aquatic triangle,” is particularly rich in birdlife. Walkers frequently spot herons, kingfishers, and moorhens, while otters are occasionally seen along quieter stretches.

The trail’s gentle pace makes it easy to pause for observation. Waterways Ireland recommends keeping a respectful distance from nesting birds, especially between April and July. Cyclists and walkers should also note that the mixed surface – grassy towpath, compacted clay, and gravel – can become soft after heavy rain, so sturdy footwear is advisable.

Practical Information

Waymarking & Surface: Look for the yellow arrow on a black background. The surface is predominantly grassy, with sections of compacted clay and gravel. Temporary fencing or gravel upgrades occasionally appear during maintenance; these are clearly signposted with alternative side-road diversions.

Maps & Audio Guide: Free PDF stage maps are available from the official Sport Ireland page, covering each section from Lowtown to St Mullins. A complimentary audio guide, split into 35 short tracks, can be downloaded via the GuidiGO app through Ingenious Ireland. The guide works offline and provides historical context, navigation tips, and local stories.

Best Time to Visit: The trail is open year-round. April through September offers the longest daylight hours and the most reliable footing, though the flat profile means the route remains walkable in winter provided you dress for the weather.

Getting There & Staying

Public transport reaches several key points along the route. Bus Éireann services stop at Lowtown and Robertstown, while the Dublin–Waterford rail line serves Athy and Carlow. St Mullins does not have regular public transport, so walkers finishing the trail typically arrange a private transfer or drive back from Carlow.

Accommodation is straightforward to arrange. Most towns display the Walkers-Welcome B&B symbol, indicating drying racks, secure storage, and local route advice. Many providers also offer luggage transfer between stages, which is useful for multi-day walkers. If you prefer a shorter commitment, the Athy to Bert Bridge route (3.7 km) or the Rathangan to Monasterevin stretch (7 km) are well-signposted, take about an hour, and have parking and refreshments at both ends.

Book B&Bs ahead in peak summer months, and check local lock operation schedules if you plan to cycle the towpath, as some sections close temporarily for maintenance. The Barrow Way rewards a steady pace, with history and river views unfolding with every kilometre.
