Overview
The Avonmore River (Irish: An Abhainn Mhór, meaning “the big river”) is one of County Wicklow’s most culturally significant waterways. Rising in the Wicklow Mountains, it flows roughly 30 km south-west through forested valleys, past historic estates, and into the heart of East Wicklow. The river is best known for its confluence with the Avonbeg, a site immortalised in Irish literature and now a protected interpretive park. Whether you are planning a gentle woodland walk, a day of literary history, or a quiet picnic by the water, the Avonmore corridor offers a well-connected route through some of the county’s most accessible natural landscapes.
From Source to Confluence
Near Rathdrum, the Avonmore passes through the grounds of Avondale House, once the family seat of Irish nationalist Charles Stewart Parnell. A few kilometres further south, the river meets the Avonbeg at the Meeting of the Waters (Irish: Cumar an dá Uisce). The combined flow becomes the River Avoca, which travels east through the Vale of Avoca and empties into the Irish Sea at Arklow. The entire course remains within County Wicklow, making it a self-contained catchment that reflects the county’s varied geology and land use.
Literary Legacy at the Meeting of the Waters
The confluence gained international fame in 1808 when poet Thomas Moore published The Meeting of the Waters, set to the traditional air “The Old Head of Dennis”. Moore visited the valley in the summer of 1807 and was struck by the visual contrast between the two streams as they merged:
There is not in the wide world a valley so sweet / As that vale in whose bosom the bright waters meet…
The poem quickly entered the Irish songbook and remains one of Moore’s most performed “Irish Melodies”. Today, the interpretive park at the confluence features bronze tablets displaying the verses line by line, alongside a bust of Moore and panels explaining the local geology. The site is open year-round, free of charge, and includes wheelchair-accessible paths and a viewing platform positioned to catch the morning light across the water.
Walking the Avonmore Way
The Avonmore Way is a 12 km linear trail that links Laragh and Rathdrum, following the river through some of the county’s finest native woodland. Waymarked with the official yellow “walking man” symbol, the route is graded easy with an elevation gain of 200–350 m. Most walkers complete it in two to four hours, depending on their chosen start and finish points.
Key trail features include:
- Clara Vale Nature Reserve – County Wicklow’s largest semi-natural woodland, featuring raised boardwalks, ancient oaks, and seasonal wildflowers.
- Samuel Hayes Bridge – An 18th-century single-span pedestrian bridge designed by the Avondale MP and noted arborist. It connects the trail directly into Rathdrum.
- Nolan’s Bridge – An early stone crossing near the northern trailhead.
- Suspension bridge – A lightweight footbridge offering a slight thrill near the village end.
The trail is well-surfaced in sections but includes forest tracks and uneven ground, meaning it is not suitable for wheelchairs. Dogs are welcome on the wider route but must be kept on a lead through Clara Vale and near nesting areas, particularly where Red Kites are being monitored. Public toilets and a café are available at Hidden Valley Resort near Rathdrum, while free parking is provided at both the Trooperstown and Laragh trailheads.
Historic Estates & Conservation
Water quality is a key focus of the Waters of LIFE project, an EU-funded Integrated Project running through March 2028. The Avonmore catchment, covering approximately 141 km², is one of the project’s six designated national demonstration catchments. Instead of traditional policing, the initiative works collaboratively with local landowners and foresters, trialing a voluntary Results-Based Agri-Environmental Scheme (RBAPS) that pays incentives for habitat improvement to help protect and restore high-status water bodies in the area.
For visitors interested in the estate heritage, Avondale House offers guided tours of period rooms and Parnell memorabilia during the May–September season. The adjacent Beyond the Trees nature resort adds a modern layer to the landscape, featuring the UK and Ireland’s longest treetop walk and a 90-metre spiral slide, both overlooking the Avonmore corridor.
Practical Information
- Getting there: The R755 connects Laragh and Rathdrum to the N11. Bus Éireann routes 133 and 133A stop in both villages. The nearest rail station is Rathdrum, with direct services from Dublin Heuston.
- Parking: Free car parks are available at the Trooperstown and Laragh trailheads, and at the Meeting of the Waters interpretive park. Spaces fill quickly on summer weekends.
- Facilities: Picnic tables and public toilets are located at the Meeting of the Waters park and Hidden Valley Resort. Rathdrum and Laragh have multiple cafés, pubs and convenience stores.
- Best time to visit: Late spring to early autumn offers the clearest water, full woodland colour, and longer daylight. Early morning visits to the confluence provide the best conditions for photography and wildlife observation.
- Accessibility: The Meeting of the Waters park is fully accessible. The Avonmore Way involves uneven forest tracks and steps, making it unsuitable for wheelchairs. Sturdy footwear is recommended for the trail, especially after rain.
Plan your arrival at the Meeting of the Waters car park before 9:00 am to avoid peak summer traffic, and allow extra time to walk the boardwalks in Clara Vale where the river runs closest to the trail.
