Overview
The River Inny is an 88.5 km waterway in the Shannon River Basin that cuts a steady course through the Irish Midlands. It begins as a small stream on the slopes of Slieve na Calliagh near Oldcastle in County Meath, an area historically associated with the megalithic tombs of Loughcrew. From here, the river – sometimes called the Upper Inny or Ross River in its earliest reaches – flows south before entering Lough Sheelin, where it crosses the meeting point of three counties.
From Lough Sheelin onward, the Inny takes on a more defined character. It passes through Lough Kinale, Lough Derravaragh and Lough Iron, each adding volume and shifting the landscape from limestone bedrock to varied quartzite tributaries. The river frequently doubles as a county boundary, tracing the edges of Meath, Cavan, Westmeath and Longford before finally emptying into Lough Ree at Inny Bay. The result is a waterway that feels both rural and deeply connected to the region’s transport and agricultural history.
History & Local Legend
The Inny has shaped local life for centuries. Its reliable flow once powered a series of water mills, most notably the pair at Tenelick near Abbeyshrule. By the 1960s, however, land drainage works removed the weir at Newcastle, which had fed a generator and sawmill for the nearby estate. The change also closed the millrace at Ballymahon, silencing a waterfall that had roared for roughly a century. Today, the river’s calmer profile suits recreation rather than industry.
The name Inny comes from the Irish Abhainn Eithne, meaning Eithne’s River. According to local tradition, Princess Eithne drowned in the rapids near Tenelick, and the waterway was named in her memory. The river’s cultural footprint extends to engineering as well: at Abbeyshrule, the Whitworth Aqueduct carries the Royal Canal across the Inny. Built in the 19th century, it still functions as a water supply point for the canal, making it one of the most photographed intersections of river and man-made waterway in the Midlands.
What to See & Do
Coarse Fishing
The Inny is widely regarded as a top-class coarse fishery. The water is consistently clean and well-oxygenated, supporting healthy populations of roach, bream, perch, tench and pike. Anglers favour the stretch below Newcastle bridge, where the river deepens to between 1.5 m and over 3 m under normal conditions. The mix of shallow riffles and deeper pools creates ideal holding water for bottom-feeding species, while the slower sections near the lakes offer good opportunities for float fishing. A valid Irish Rod Licence is required, and local angling clubs often manage specific stretches.
Kayaking & Canoeing
Below Newcastle bridge, the Inny’s gradient increases, producing a series of gentle rapids that attract paddlers from across the region. The Inny Kayak Club, established in 1993 and based in Ballymahon, operates on a roughly 4 km run that features pour-overs, stoppers, standing waves and technical holes. It is the only stretch of this type in the midlands, making it a valuable training ground for beginners and a reliable thrill for experienced paddlers. The club follows Canoeing Ireland safety guidelines and can advise on launch points and water levels.
Summer Tubing
Further downstream, near Ballymahon, the river’s flow slows enough for a popular summer activity: white-water tubing. Families and groups often drift downstream on inflatable tubes, enjoying a low-cost, relaxed way to experience the water. The route is informal, so participants should wear life jackets, check current conditions and stay close to the bank.
Wildlife & Walking
Because the Inny ranks among Ireland’s cleanest rivers, it supports a steady presence of wildlife. Kingfishers are a regular sight along the gravel banks, while herons, grebes and migratory waterfowl use the lake sections for feeding. Otters have been spotted in quieter reaches, particularly near Ballymahon and Abbeyshrule.
Walkers can follow the river through several heritage points, including the Whitworth Aqueduct and the ruins of the old Ballymahon mill. For a longer route, the Royal Canal Greenway runs parallel to parts of the Inny and connects easily to the Old Rail Trail Greenway, offering flat, off-road paths that link towns, locks and harbours. Cycling and walking access is straightforward, with public paths and greenway entry points providing safe routes away from main roads.

Combine a day on the Inny with a stop at the nearby Corlea Trackway Visitor Centre or a walk along the Greenway to stretch your visit into a full midland itinerary. Check the Inny Kayak Club’s seasonal schedule before paddling, as water levels and launch availability shift with rainfall and upstream conditions.
