Overview
The River Inny is a 88.5 km (55 mi) tributary of the Shannon River Basin, celebrated for its clear waters, varied habitats and rich cultural landscape. Originating on the slopes of Slieve na Calliagh near Oldcastle in County Meath, the river traverses a patchwork of counties – Meath, Cavan, Westmeath and Longford – before emptying into Lough Ree at Inny Bay. Along its course the Inny feeds a string of lakes, including Lough Sheelin, Lough Kinale, Lough Derravaragh, Lough Iron and finally the expansive Lough Ree, each offering distinct scenery and wildlife.
History & Background
The upper reaches of the Inny, sometimes called the Upper Inny or Ross River, flow through a landscape dotted with megalithic tombs at Loughcrew, underscoring the river’s ancient significance. Historically the river formed natural county boundaries – first between Meath and Cavan, later between Westmeath and Cavan, and finally between Longford and Westmeath. At Abbeyshrule the Whitworth Aqueduct carries the Royal Canal over the Inny, a striking piece of 19th‑century engineering that still supplies water to the canal.
Mythology also runs deep: near Tenelick the tragic tale of Princess Eithne drowning in the rapids gave the river its name. The rapids once powered two mills at Tenelick, and later a sawmill and generator at Newcastle bridge in the 1960s, though the original weir was removed, silencing a century‑old waterfall.
What to See & Do
Fishing
The Inny is a top‑class coarse fishery. Anglers report excellent catches of roach, bream, perch, tench and pike along its length, especially below Newcastle bridge where the river deepens to 3 m in places. The river’s clean, oxygen‑rich waters support healthy fish stocks, making it a favourite for both local and visiting anglers.
Paddling & Kayaking
The river’s gentle rapids make it a popular venue for canoeing and kayaking. The Inny Kayak Club, founded in 1993, operates from the stretch downstream of Ballymahon and offers information on launch points, safety guidelines and local events. More details are available on their website: Inny Kayak Club.
Tubing & Family Fun
Further downstream, near Ballymahon, the river provides a natural white‑water tubing experience. Local Facebook posts highlight the fun of drifting downstream on inflatable tubes, a low‑cost activity that families enjoy during the summer months.
Wildlife Watching
Because the Inny is one of Ireland’s cleanest rivers, it supports a diverse array of wildlife. Birdwatchers can spot kingfishers, herons and occasional otters along the banks, while the surrounding lakes host migratory waterfowl. The river’s limestone and quartzite tributaries create varied micro‑habitats that enrich the ecological tapestry.
Heritage Walks
Walkers can follow the river’s course through historic sites such as the Whitworth Aqueduct, the ruins of the old mill at Ballymahon, and the scenic Lough Derravaragh – famed for the legend of the Children of Lir. The nearby Royal Canal Greenway offers a flat, off‑road trail that runs parallel to parts of the Inny, providing easy access for cyclists and walkers who wish to combine river scenery with canal heritage.
Practical Information
The River Inny is free to access; there are no admission fees or formal opening hours. Most access points are public, often located at village bridges, car parks or designated greenway entry points. Parking is generally available at nearby towns such as Ballymahon, Abbeyshrule and Mullingar (via the Royal Canal Greenway car‑park map).
For anglers, a Rod Licence is required in Ireland, and local angling clubs may issue day permits for specific stretches. The river’s depth varies from about 1.5 m to over 3 m under normal water levels, so boaters should check local conditions before launching.
The Longford County Council provides a concise visitor page with additional details and a map of the river’s route: River Inny – Longford County Council. For kayaking enquiries, the Inny Kayak Club website offers contact information and event listings.
If you plan to combine a river visit with a longer outdoor adventure, consider linking the Inny to the Royal Canal Greenway (130 km) or the Old Rail Trail Greenway (42 km) for extended cycling or walking routes that showcase the Midlands’ waterways.
The River Inny offers a rare blend of pristine nature, sport fishing, paddling thrills and mythic history – all within easy reach of Ireland’s central counties.
