Clashganny Forest lies on the gentle hillsides beside the River Barrow in County Carlow. The area is free to enter and is served by two on‑site car parks – the Clashganny Lock car park and the Viewing Point car park – with basic visitor facilities. Two well‑marked loops criss‑cross the ancient 19th‑century woodland, offering walkers, cyclists and families a blend of river scenery, mature deciduous trees and quiet riverbank paths.

History & Background

The River Barrow formed a vital part of the Barrow Navigation from the late 1700s until the 1960s, linking inland farms and towns to Dublin’s breweries. Clashganny Lock is a fine example of Victorian engineering; stone chambers and wooden gates once regulated the flow of barges carrying grain, timber and even Guinness. After commercial traffic ceased, volunteers from the Inland Waterways Association restored the lock to working order, and it is occasionally opened for public demonstration.

The surrounding forest was originally planted in the 1800s for timber production and has since become a haven for native flora such as ferns, bluebells and primroses. Hidden among the trees is a mass rock, a granite slab used for clandestine Catholic services during Penal times, adding a poignant historical layer to the natural setting.

Wildlife Highlights

The mature deciduous wood supports a variety of wildlife. Birdwatchers can spot willow warbler, great spotted woodpecker, and occasional kingfisher along the river. In spring the forest floor is carpeted with bluebells and primroses, while autumn brings a display of amber‑coloured leaves. The river itself holds brown trout, making it a quiet spot for anglers.

What to See & Do

  • Clashganny Lock Loop – 3.6 km (≈1½ hours). Marked with green‑and‑yellow arrows, the moderate loop starts at the lock car park, follows a gentle forest road downhill, then joins the riverside towpath. Walkers pass Clashganny Lock, the nearby Ballykeenan Lock (see Barrow Way Locks: Ballyellen and Ballykeenan), small waterfalls and a uniquely crooked old tree, with continual river vistas.
  • Clashganny Viewing Point Loop – 5.5 km (≈2 hours). Signposted with purple arrows, this slightly longer circuit begins at the Viewing Point car park, descends to the towpath, then climbs back through deeper woodland, revisiting the mass rock before reaching a panoramic viewpoint.
  • Flora & Fauna – The forest hosts ferns, bluebells, primroses and a chorus of native birds such as willow warbler and great spotted woodpecker, making it ideal for quiet nature observation.
  • Recreation – The lock basin is popular for canoeing and kayaking; in summer it is lifeguarded for swimming. The Barrow Line – a 25 km tow‑path trail – runs close by, inviting longer walks or bike rides that connect Clashganny with other river towns.
  • Food & Refreshments – After a walk, the Clashganny House Restaurant offers a well‑known Sunday lunch and other Irish dishes, perfect for a post‑trek meal.
  • Nearby Attractions – The historic Borris House (6.4 km) and the village of Borris provide cafés, pubs and accommodation. The charming town of Graiguenamanagh, a short drive away, adds further cultural sites and eateries.

Nearby Walks & Connections

The Barrow Way, a long‑distance walking route that follows the River Barrow from its source to the sea, passes close to Clashganny Forest. Sections of the Barrow Line tow‑path are well‑signposted and can be combined with the forest loops for a longer day out. Cyclists can also link onto the Barrow Way cycle route, which runs parallel to the tow‑path.
