The River Fergus is a quiet, rural waterway in County Clare that flows from the northwest end of Inchiquin Lough near the village of Corofin. The river is characterized as a gently meandering stream, making it accessible to paddlers of varying experience levels. A typical route involves launching from Inchiquin Lough and paddling upstream along the Fergus in the direction of Kilnaboy, then returning downstream to the starting point.

The surrounding landscape includes historic castle ruins, remnants of structures abandoned in the 1820s and 1830s when owners removed roofs to avoid property taxes, leaving nature to reclaim the stonework over time. Ivy and vines now cover much of these ruins, which are visible from the water.

Wildlife is a notable feature of paddling on the Fergus. Kingfishers are regularly spotted along the riverbanks, and swans are commonly encountered on the water. Evening paddles have produced murmurations of starlings in the area. The river passes through a rural, largely undeveloped corridor that supports a variety of birdlife.

The Burren Outdoor Education and Training Centre, based in Bell Harbour, County Clare, offers guided kayaking on the River Fergus near Corofin. North Clare Sea Kayaking is another local operator active on this stretch of water. The river also connects to Ballyalla Lake in County Clare and is referenced as part of the broader paddling options along Ireland's Wild Atlantic Way corridor in the region.
