Inchavore River

Overview

The Inchavore River (Irish: Inse Mhór) is the graceful watercourse that threads the broad, grassy plain of the Inchavore Valley, the head of Lough Dan in County Wicklow. Its sinuous, meandering channel displays textbook‑perfect ox‑bow formations, a legacy of the ancient glacier that carved the deep U‑shaped valley. Flanked by rush‑laden meadows, the river is a living illustration of Ireland’s glacial heritage and a haven for a surprising diversity of birds and mammals.

History & Landscape

The name Inse means “river meadow” in Irish, while Mhór translates as “great” or “large”. Together they give Inse Mhór – the Great Inch – which was anglicised to Inchavore. The term “Inch” appears in many place‑names across the eastern counties, denoting low‑lying river meadows, whereas the western equivalent is srath.

On the far side of the valley, the steep, rocky ground known locally as “The Scoils” or “Scoyles” derives from the Irish scoilt (split), describing the fissured terrain that drops away from the Cloghoge peaks. The valley’s geology, a classic glacial trough, is framed by the surrounding peaks of Knocknacloghoge and Kanturk, and the whole area enjoys protection as a Special Area of Conservation under European law.

What to See & Do

Wildlife Watching

The river and its surrounding wetlands support a rich assemblage of birds. Dippers and grey wagtails breed along the fast‑flowing sections, while herons and cormorants roost near the river mouth. The cliffs above the lake host peregrine falcons, and the broader valley is a refuge for deer, hares, rabbits, otters, red grouse, hen harrier, snipe, pheasant and merlin. Bird‑watchers will find the river’s banks a rewarding spot for spotting both resident and migratory species, especially in the early morning when otters are most active.

Short Hike – Inchavore Valley Loop

A family‑friendly, one‑hour loop starts at the Lough Dan Scout Centre (grid reference 0 156023). Walk 1 km along the paved road (a narrow, single‑file stretch) to the road’s end, gaining about 50 m in elevation. From there, cross the bridge, climb the stile, and follow the access pathway that contours before descending into the valley. The 2 km return trek is largely flat, with a total walking time of roughly 1 hour 15 minutes on the return leg due to the gentle uphill.

The route was kindly established by local landowners; visitors are asked to keep noise to a minimum and practice Leave‑No‑Trace principles. Along the way, the path offers views of the river’s ox‑bow bends, the surrounding rushy meadow, and, on a clear day, the distant peaks of the Wicklow spine.

Picnic & Adventure

At the western end of Lough Dan lies a sandy beach perfect for a lakeside lunch. For the more adventurous, the slopes of Knocknacloghoge Mountain provide informal bouldering opportunities, while the small oak cops further up the river make a rustic overnight spot for scout groups.

Scenic Photography

The river’s meanders, framed by the flat meadow and the dramatic backdrop of the Cloghoge valley, create striking compositions for landscape photography. The contrast between the calm water and the rugged “Scoils” adds visual interest, especially in the soft light of early morning or late afternoon.

Extended Walks & Connections

The Inchavore Valley loop can be used as a launch‑pad for longer walks that explore the wider Wicklow Mountains. The GPS‑routes guide describes a 5.6‑mile (9 km) Lough Dan walk that continues west along the Cloghoge River, skirts the northern shore of Lough Dan and then climbs toward Knocknacloghoge (532 m). From the summit you gain panoramic views over Lough Dan, Lough Tay and the surrounding peaks.

For ambitious walkers, the trail can be linked to the Wicklow Way. Heading north from the valley you reach the historic Pier Gates, a popular entry point to the Wicklow Way, while heading south connects to the Ballinastoe Forest mountain‑bike trails and the J.B. Malone memorial on Djouce Mountain.

Nearby attractions that make excellent add‑ons include:

• Lough Tay – the “Guinness Lake” with its striking turquoise water.
• Luggala – a classic hill‑walking destination a short drive away.
• Vartry Reservoir – accessible via a well‑marked trail from the valley.
• Powerscourt Waterfall – Ireland’s highest waterfall, reachable via the R759.
• Crone Woods – a broad‑leaf woodland ideal for a gentle stroll.

These extensions allow a day‑trip that combines river wildlife, mountain scenery and historic way‑marks.

Seasonal Highlights

• Spring – The rush‑laden meadows burst into colour with wildflowers such as marsh marigold and early purple orchid, attracting butterflies and dragonflies.
• Summer – Long daylight hours make the loop ideal for families; the sandy beach at Lough Dan is popular for picnics and a quick dip.
• Autumn – The surrounding woodlands turn amber and gold, providing dramatic backdrops for photography and a chance to hear the rasp of migrating birds.
• Winter – Snow often coats the “Scoils” cliffs, creating a stark, photogenic landscape. Dippers and otters remain active, offering rewarding wildlife spotting in quieter conditions.

Visitor Resources

• Trail video – A short YouTube guide titled Inchavore River Trail to Lough Dan (2026) gives a visual overview of the route and can help first‑time walkers plan their day.
• GPX file – The Lough Dan walk GPX file is available from the GPS‑routes site for download to a handheld device.
• Maps – OS Map sheet 56 (scale 1:50 000) covers the area in detail. The trail is also marked on the official Wicklow Way way‑marking system.
• Guidelines – As the valley lies within a Special Area of Conservation, stay on the marked path, keep dogs on a leash and take all litter with you.

Practical Information

The Inchavore Valley hike is self‑guided and free of charge. The starting point, Lough Dan Scout Centre, offers a small car park (approximately 15 spaces). During the summer months the car park can fill quickly, so arriving early is advisable. The road to the valley is narrow and single‑track, so drivers should proceed with caution and yield to on‑coming traffic.

The access pathway after the bridge is well‑maintained but may be muddy after rain. No formal facilities (toilets, cafés) exist along the river itself, so plan accordingly.

The area is part of the Wicklow Way network, and the short loop can be combined with longer sections of the Wicklow Way for more ambitious walkers. Because the valley lies within a Special Area of Conservation, dogs should be kept on a leash, and any litter must be taken back to the car.

For detailed maps, refer to OS Map sheet 56 (scale 1:50 000). The hike is suitable for children (Cubs and Beavers) and groups seeking a brief immersion in Wicklow’s wild heart.

Key Details

Getting There The valley is reached most easily from the Roundwood side of Lough Dan via the Pier Gates, or from the Military Road to the west. Public transport to Roundwood is available from Dublin, after which a short drive (≈30 km) brings you to the Scout Centre. Private car access is the most convenient option for families.
