The River Suir in County Tipperary flows through the southeast of Ireland, forming the basis of the Suir Blueway, one of Ireland's four officially accredited blueways. The paddling trail runs 53 km from Cahir to Carrick-on-Suir, passing through Clonmel along the way. The river is accessible roughly two hours from Dublin and one hour from Cork via the M8 motorway.

The character of the river changes noticeably along its length. The section near Cahir tends to be calmer and slower-moving, making it suitable for beginners and those looking for a more relaxed outing. Moving downstream through Clonmel, the water becomes livelier with more active stretches. The Kilsheelan to Carrick-on-Suir section is described as predominantly flat and slow-running, again appropriate for less experienced paddlers. The Cahir to Carrick-on-Suir corridor is considered the most scenic stretch of the route, passing through the Suir Valley with views of medieval towns, castle ruins, tower houses, churches, and lush farmland. Notable landmarks along the route include Cahir Castle, Ormond Castle, and the Swiss Cottage.

In Clonmel, a fish ladder feature known as the Fishboxes serves as the primary freestyle and playboating spot in Ireland. Located in the centre of town, it functions from a Clonmel gauge reading of 0.4 and below. The feature is large enough for playboating and hosts the Southeast Freestyle Festival. One noted hazard at this location is the presence of metal bars within the wave that can damage boats.

Paddlers should be aware of a biosecurity concern on the Suir: the river is affected by Crayfish plague, and Canoeing Ireland advises against paddling here unless it is your local river, in order to prevent spreading the disease to other waterways. Washing and drying gear thoroughly before and after paddling is strongly recommended.

The Suir Blueway infrastructure includes access points, equipment hire providers, guided tour operators, and accommodation options along the route. A 21 km walking and cycling trail runs alongside the water trail between Clonmel and Carrick-on-Suir along an old towpath formerly used by horse-drawn barges. Wildlife along the river includes kingfishers, among other species.
