Overview
The Owenmore River cuts a quiet path through the agricultural heartland of County Sligo. Rising near the village of Gurteen, it meanders past the historic Templehouse Lake, flows through the market town of Collooney, and eventually joins the Unshin River. From that confluence, it becomes the Ballysadare River, feeding into the wider Shannon-Ballysadare waterway. Despite its Irish name, Abhainn Mhór (literally “big river”), the Owenmore is a modest, low-gradient stream. That gentle character is exactly what makes it appealing: there’s no rush here, just steady water and unspoilt banks ideal for a relaxed day out.
History & Landscape
The river’s valley is a classic example of Sligo’s drumlin countryside – low, rolling hills draped in pasture and bordered by native woodland. The most notable historic feature along its course is the Templehouse estate. Founded in the 17th century, the estate once controlled the fertile floodplains downstream. Today, only weathered stone walls and the outline of the old demesne remain, blending quietly into the trees and hedgerows.
Historically, the Owenmore’s downstream connection to the Shannon-Ballysadare system made it part of a vital commercial route. Before railroads and modern roads, this waterway carried timber, grain and livestock from the midlands to the coast. While commercial traffic vanished decades ago, the riverbed still bears the wider, deeper cuts made by old canalisation works, which now create calm pools perfect for wildlife and recreation.
What to Do
Angling
The Owenmore is a favourite among local coarse fishermen and trout anglers. The river supports steady populations of bream, perch, pike, rudd and brown trout. The most productive stretch sits around the old Templehouse bridge, where the current slows and deepens. No fishing permit is required for this section, so you can simply arrive with your rod, bait and a stool. Bank fishing is the standard approach here; the water is too shallow for boat fishing, and the gentle gradient means fish tend to hold in deeper eddies behind rocks or fallen timber. Early morning and late evening tend to yield the best results, especially when the light filters through the overhanging willows.
Kayaking & Paddling
For those with a kayak or canoe, the Owenmore offers a straightforward Grade 1 run. The current is predictable and slow, making it a solid choice for beginners, families teaching children to paddle, or anyone looking to escape faster-moving rivers. The main route typically starts near Templehouse Lake and continues downstream toward Collooney. Paddlers should keep an eye out for submerged branches and overhanging vegetation, particularly after wet weather. A dry bag for essentials and a basic whistle are sensible precautions, but the stretch is generally hazard-free and easy to portage if needed.
Riverside Walks & Wildlife
You don’t need gear to enjoy the Owenmore. The banks are threaded with informal footpaths and farm tracks that make for peaceful walks. The surrounding copses and wet meadows attract a reliable cast of wildlife. Kingfishers are frequently spotted flashing over the shallower runs, while the quieter, reed-lined margins provide cover for otters and badgers. If you’re visiting between March and May, the river valley is an excellent spot for spotting migrating waders and songbirds. The stone bridge at Templehouse and the reflective waters of the adjacent lake create a consistent backdrop for photography, regardless of the season.
Getting There & Practical Information
The most direct access is via the R293 road from Gurteen. Signage is minimal, so following the road as it approaches the Templehouse area is the best guide. A small, unstaffed car park sits near Templehouse Lake, offering free parking for anglers, paddlers and walkers. The space is modest and fills quickly on dry weekends, so arriving before midday is advisable. The ground around the car park and along the riverbank can be soft and uneven; waterproof boots or sturdy walking shoes are strongly recommended.
Public transport to the river is limited. The nearest regular bus stop is in Collooney, roughly five kilometres away. From there, a local taxi or a brisk walk along the rural roads will get you to the river. Train travellers can alight at Sligo town station and connect via bus or taxi.
There are no entry fees, ticket booths or formal opening hours. The river is open year-round, but water levels respond quickly to rainfall. During prolonged wet spells, the current can strengthen and visibility can drop, so checking the Met Éireann forecast before heading out is wise. For guided fishing sessions or introductory kayaking lessons, several local outdoor providers based in Collooney and Sligo town run seasonal packages. Booking in advance is recommended during the summer months.
Nearby Attractions
A short drive inland brings you to Collooney, a working market town with independent shops, traditional pubs and the preserved ruins of Collooney Railway Station. Heading west, the dramatic flat-topped peak of Benbulben dominates the horizon and anchors the surrounding forest walks and coastal trails. To the south, the historic port of Sligo town offers museums, literary heritage sites and ferry connections to the west coast. The Owenmore River makes a quiet counterpoint to these busier destinations, offering a steady rhythm of water, woodland and open sky for those who prefer to travel at a slower pace.
